Trying to FIX an ATARI JAGUAR with No Display

[@iq300gaming5]

Absolutely love your videos Vince, your so honest with your repairs and happily admit when your struggling. Wife was in the room while watching this video and said you should re-title the video to “Atari Jaguar slowly fixes itself while repair man pokes at it”

[@Mymatevince]

Haha, thank you and what a brilliant comment :-)

[@bradleycarleton8259]

Vince you are the best youtuber in the world I love you so much tysm for your efforts you put into your vids

[@Jeff121456]

The coil in the rf modulator that was misshapen was done at the factory to fine tune the inductance to adjust the output frequency/amplitude. The screw you were messing with is a core to the main coil is the main method to adjust the frequency which is why it affected the reception. Capacitors in digital electronics are mainly used for noise filtering and decoupling. In RF circuits they are also used with inductors (coils) to create tank circuits that amplify the RF signal and to block dc voltages from crossing between stages ( probably why you found a path to ground on both sides of that capacitor).

[@Mymatevince]

Cheers Jeffery :-)

Why on earth would you use RF when you have composite or better still ........RGB Scart. It's so simple plug and play and then you know for sure it's actually working or not. Not to mention the superior sound and picture quality.

Vince, really love your content man. I remember you made a poll a couple of days ago about which videos people prefer to watch, I just want to give you some feedback as an average viewer: I think the best way to describe your videos with regards to why some people prefer watching your videos is simple -- tech porn. It's as simple as that. You have this niche corner that ONLY your videos can provide and that's the analytical/troubleshooting of game systems/electronics. People like myself gravitate to these videos because they are well narrated, people can relate to you because it's not TOO techy and isn't deep enough to where people will get lost in the terminology. Yes there are a lot of "let's fix/try to fix" vids out there on KZbin, but you have this je ne sais quoi about your videos that make them distinct from the rest.

[@terjes7548]

It would be interesting to know if the "overheated" chip is cooler when the console is working vs when it didn't.

[@ChrisArmstrong194]

I suspect the chip is part of the cause, perhaps add some cheap Aluminium gpu ram mini heat sinks on those hot chips?

[@greenaum]

@@ChrisArmstrong194 Pretty sure those are the actual RAM chips. 8 of them, 8 bits each, giving 64 bits. One of the designers said, the machine isn't really 64 bits in any meaningful sense, they did it to get more bandwidth out of cheap consumer RAM chips. 64 bits out of 8 chips is more data at once than 32 bits out of 4 chips. But only a couple of parts in one of it's chips can actually handle 64 bits, mostly the rest of them use 32. The machine has 5 processors, each designed heavily around one or two particular functions. It was apparently an utter mess to program cos you've got these 5 CPUs with no obvious way of getting them to work together to produce a result. The design was apparently compromised from the usual corporate sort of bullshit, but even if it came out as the designer intended, I've no idea what they were going for. It's an odd machine, underpowered compared to the Playstation and Saturn, and what power it had, nobody knew how to use. Bizarre. Most of it's games were ports from the Amiga, which used a 68000 as it's main CPU. In the Jaguar, the 68000 is the *least* powerful chip it has, a designer said "we only put it in there to read the joysticks", it was included to give programmers something they were used to. But sadly it meant that they ported code from the Amiga or Megadrive, and mostly ignored the Jag's other hardware, which made it look pathetic running outdated games that didn't use it's power. But software houses weren't willing to put the full effort into learning it, because it hadn't sold enough to justify the investment.

[@chrisb15151]

I tested 3 jags a couple of weeks ago, none of them were working. I basically cleaned the board a few times with ipa. Still nothing, tried to see if continuity between the board & the pin connector. All fine. I ordered an av out cable & all worked everytime. It puzzled me at the time & still does. I think at the end you mentioning about PAL signal does play into on these boards. The ones I have don't have the same alterations as your board. Superb video btw 👍

[@pds8475]

L is an inductor, coil not capacitors. If it starts playing up again I would suggest you reflow the chips as a dry joint on one of the pins could make it not boot and if you put pressure on the chip say while you were cleaning the game slot. it could make the pin contact.

[@Mymatevince]

Thanks PDS, I really should have recognised that 'L' means inductor and not capacitor. Yes I will keep an eye on it and if it fails again I will revisit and reflow :-)

Yay more retro stuff! I had an Atari Jaguar growing up. Only had one game though: Alien vs. Predator. That start up music with the roar and the little tune is super nostalgic.

[@Asriazh]

With how you went about doing things, turning the Jaguar on and off, leaving it on, leaving it off repeatedly, i think it might have been a bad capacitor after all, reforming itself up to the point where things actually started working again. Capacitors can do that at times when they're powered on for long enough. Apart from that i have no real clue how it's working now when it didn't before *lol* Not my favorite console, but it's always nice to save old hardware ^_^

Interesting fact about the Atari Jaguar: when Atari went bankrupt, they sold the Jaguar molds to a dental camera company. If you look it up, you'll see pictures of the flipped silver Atari Jaguar, it's exactly the same, which is hilarious to me. Also, the AVGN video on it is pretty informative.

Another great vlog from Vince,

[@iain999999999999999]

Bear in mind the technology of televisions back when the Jaguar was designed. Usually tuned by turning mechanical tuning dials of some description, not something run by microcontroller. I imagine it'll work just fine on your old TVs that use manual tuners (eg the boombox TV). Analogue tuners on modern TVs... Not convinced they're a priority. I mean, none of the reviewers will notice it; and few consumers will notice if the analogue tuner isn't great.

[@mikehensley78]

Hell yeah! I've been waiting for another video. Another obscure item also. Nobody is doing board repair on a Jaguar. Very cool video IMO. I recall when jaguars came out. The ads put so much hype on them and they sucked, i guess. I've never seen one in person. It was something to do with saying they were a 64bit console. Again, awesome video.

[@Mymatevince]

Cheers Mike :-)

[@much1276]

I also think it was a dirty cardridge connector. Which also caused a short (maybe with a slightly high resistance or impendance). After cleaning it it was better, the ipa makes a better connection, as it evapuates the connection got bad again. The RF Signal seem to be ok. I live in germany and when I connect a console via RF, I always had (analog TV here is gone) to tune in the Channel by my own. The same with old analog TV Signals. We do not have Channels with fixed RF bandwiths, every channel has the same. To get our TV channels we had to tune in the right frequency. most TV have an automatic Channel finder which goes to all frequencys and stops if the Image is ok.

Consoles and computers that tune in on RF required tuning to a different channel once channel 5 launched. This passed without much fanfare so many people missed it. This is why you're having trouble tuning it on RF.

[@lawrencecavens5760]

Yep I remember those slotted games were a real problem where the receptical would be the issue from corrosion and or Oxidation to soldering joint problems because of the force it takes to insert and remove the cartridge . you've fixed it by cleaning it wayda go there Vince... Also You probably have a NTSC model where you have PAL for tuning the RF is set to NTSC which is why your TV doesn't work on RF out put

[@michaelthomas3646]

my personal guess would be the switch is ground connected, and there is a 5v rail (LED to switch), and a 12v rail leading to the switch. so when the switch was pressed it would light up the LED, but dirt or something stopping the 12v rail from connecting to the switch. hense why the LED came on, but the console didn't fully switch on. and also why it is working all the time at the end of the video.

[@yoloswaggins7611]

Those caps on top of that chip on the right look like tantalums. Those are well known for being terrible. They can sometimes fail open circuit, sometimes they become a dead short and explode. I would suggest replacing them. Not sure if they'll cause intermittent issues like you're experiencing.

[@1337Shockwav3]

[@supermega1]

Good video thanks Here in OZ we have VHF and UHF TV band and I believe in the UK VHF band was discontinued in the 70''s ? Your UK TV is picking up a ghost/harmonic image of the vhf modulator in the unit on UHF.I had the opposite problem once with a UK pong game I purchased in the UK. Changing to Australia on the TV is changing the tuning range to include VHF.The output of the modulator would be between 54 -225 mhz (AU ch 0 to 12) I think the bridged cap would ber for DC blocking on some units.

[@BADSeCt0R2XP]

Excellent job mate. Now grab your self a copy of tempest 2000 and Rayman (or a jag everdrive and the roms, i don't judge) and enjoy your jag :)

[@adventureridergirl]

The first thing I do when I get an old computer/game console/etc. is take it apart and give any PCBs a good clean with electrical contact cleaner. Then if there are any card slots, edge connectors, RAM slots, etc. I hit those with just a little DeoxIT. I can't tell you how many "defective" components I've brought back to life just by giving them a proper cleaning. After I clean everything up I start checking other components, RTC battery, capacitors, etc. By cleaning the whole board first you rule out any minor shorts due to contamination (liquid, flux, debris, etc.) and DeoxIT is great for making sure you have good contact between any game carts, add on cards, controllers, etc.

[@Mymatevince]

Thanks for the tips :-)

[@howtowithelizabeth7513]

I think the screw thing in the box at 42:00 is an adjustor for the signal

[@antonia4722]

That little screw in the tuner is an intermediate Frequency Transformer. Part of the tuning circuitry.

[@mrbridger5]

You could have saved days of work, just blow into the cartridge, that fixes everything 😄

[@unimportant5122]

Afaik, the UK used PAL-I, whereas most of the rest of western europe used PAL-B, this might explain the compatibility issues. The inductor that's spread apart in the tuner is part of a finely tuned LC tank oscillator. Physically moving the inductor actually changes the oscillation frequency so it's set by hand and then glued/laquered to keep it in place.

[@TheChinasky71]

You're correct, the "screw" should be intended for fine tuning the signal. The c64 had a similar rf-modulator as far as I know. Maybe one of the crystals used to give the rf frequency is out of sync or non working.

[@markholdahl6511]

I know this is an old thread, but I found the set up instructions for the Jaguar, and it said that PAL-B connects to VHF and PAL-I connects to UHF (tho does not say which channel). Of course, if there's only 1 antenna port, it doesn't matter...

FWLIW: To me your frustrating issues smell of cheapness on Atari's part - cut a corner here and there to save pennies on components and this can often be the result. A particular problem with analogue TV - I bet a replacement RF box would work better, if made by somebody more reputable.

[@michaelprice3031]

I wish I had as much patience as you. It's definitely frustrating to fix something without knowing what you did to fix it.

[@welliben]

Going from memory the Jaguar was released prior to the holiday season in America only (well specifically a New York 'test' market). Europe was meant to get it before the Christmas period as well, but due to manufacture issues it didn't happen. As the Jag was the hottest new hardware at the time (believe it or not!) quite a few places were importing them at astronomic mark ups so it could well in theory be that this console is an import. In theory if you had a another working Jag you could probably turn that pot on the modulator to tune it to the same signal as the good Jag. Cybermorph is the cheapest game because it was the pack in launch game and most consoles came with it (although a few later issues came with no game or Alien vs Predator). The Cartridge slot on the Jag is a bit finicky to say the least, and will often red screen at the best of times, usually it is just dirt. It could be that just inserting the cart enough times and the cleaning you did, did enough to clean it out.

[@h4x0rm1k35]

The Jaguar was released in the UK, I remember as my mate had 1 and was able to buy games for it because I brought it off of him when he'd done with it. he wasn't the kind for importing stuff, just buying the latest and greatest at the time and then flogging them off cheap when he'd done with them!

[@welliben]

@@h4x0rm1k35 Ah yep it did come eventually a few months later (I have two PAL consoles and the CD add on!), a shame really as I think the uptake in Europe would have been a lot better than the sales it eventually received with America as the launch market, given Atari's success with the Atari ST and is relatively low base in the US. When I got it I was actually blown away by Cybermorph believe or not, the whole goraud shaded 3D world space shooter was a bit unusual in those days... although I had come from an ST and a SNES.

Hi vince which multimeter do you use in your video would you recomend it or witch would you recomend for a beginner

[@paulkeith6358]

The Atari Jaguar if I remember rightly actually came with Cybermorph. It was a particularly crap game and no wonder that it was so cheap. If you can you should track down a copy of Tempest 2000. Tempest 2000 was a real psychedelic showcase for the system in both sound and visuals. However it is quite rare and expensive,but in my opinion one of the few games that can be considered really worthwhile getting.

[@StuartZiane]

[@jbuurk]

Using a scope (as you mentioned you have one) instead of prodding and re-soldering is a much better way of finding the underlying fault(s) and repairing it properly. Much more educational too.

[@HoudiniFontmeister]

I have repaired NES, SNES, Genesis, etc. I have fixed a lot of these old consoles. Never had a Jaguar. But I can 100% Confirm that sometimes a thorough deep cleaning is enough to fix a console (Resoldering the pins is also a good idea as well) I don't believe it was so much the corrosion preventing the pins from connecting though. I believe that something was shorting out underneath the slot. This would explain why it was messing up so often and not booting even when you shorted those two pins. The short could have been small enough to let it begin to boot then error out at the red screen as well. When you cleaned it you removed all kinds of dirt that had built up over the years. Also The system likely started working after it had a good while to dry out. Maybe it would be a fun idea to create a way to keep dust out to prevent this from happening again. Many of these die out and no one really takes the time to just deep clean them. I have a feeling that most of the Retro systems that get tossed out as defective or fried just need a deep clean. I say that because I have only ever had 1 NES that was Legit dead in 12 years of repairing them and I'd say half of them just need cleaning and soldering. Great video mate! Also The UK and Ireland use a higher frequency than The rest of Europe. Most of the older consoles are just spec'd to have the higher frequency and generally work but several are not compatible. Newer tv's just kind of work with whatever you put in (A lot of them can detect the frequency and tune in which is why the TV you tried last looked cleaner I'd guess).

[@KorAllRBare]

[@JustinPR34]

Hello love your vids keep up the good work

[@10p6]

The Jaguar did have an issue, a very dirty cart slot. This is why the 74AC244 Octal Buffer chip was getting very hot. The Jaguar cart slot can show many issues, from no screen, to red screen, to corrupt graphics and more. The RF Modulator issue is strange as the C100186 I believe is a PAL modulator for the XEGS game system and not the Jaguar, so I am guessing that could have been swapped out by someone. I am wondering now is this started out as a French system with no modulator, and someone added the C100186 to give it an RF signal. That could also be related why the capacitor was missing.

[@michaeladams9807]

Nice fix 👍👍

[@hi-friaudioman]

Two things... it's cheaper for a company to bodge a couple wires to fix an issue than remanufacture a whole new board hence the factory "mod" as you said. Secondly DSP stands for Digital Signal Processing otherwise known as "digital signaling" which can be a number of things, access for peripherals to the cpu/components of the devices logic. It could be a digital video output from the devices DSP "Digital Signal Processor", it could also be a means for the factory to test the unit and its various functions.

[@BrainHurricanes]

26:42 Are you sure your modern TV doesn't go searching for another input when you shut down the console ? Probably.

[@nightstah]

Your Logik TV panel came from Australia, yet the rest of the TV originated in the UK. I would think the mainboard or logic board would be the determining factor on whether it would display UK or Aussie frequencies (yes, both PAL). This makes me think maybe not. Considering your other TV displays it...

[@michaelmcdonald2348]

I used to get customers who brought their TV's over from continental Europe and wanted them converted. In all cases the picture would tune in perfectly but no audio. The conversion was fairly easy, just replacing some ceramic filters and a slight tuning. Have a look if you can what it's actually tuned to on the TV. I'm thinking this might be a VHF modulator. Your test TV may disable this when set to UK which would explain why it tunes in when you change country. UK only used VHF for 405 line transmissions and abandoned it for TV use in 1985 when they closed down 405. Other countries (including the Republic of Ireland with PAL-I) continued to use VHF for analogue transmissions. I suspect this console isn't a UK model. By the way the coils and parallel capacitors form a tuned circuit so you will always read a short on that capacitor because of the coil in parallel. The separated turns is how they fine tune that circuit and disturbing that would have a negative effect, which is why they stuck that glue there.

[@robtitheridge9708]

Hi vince two possible explanations for the fix 1> a capacitor in the reset circuit has reformed its self 2> the on off switch has a set of reset contacts that were dirty. As others have said the modulator is not for the UK.

[@Mymatevince]

Cheers Rob, a lot have mentioned the power switch in the comments, maybe it was just dirty contacts!!!! If only I had thought of that I could have saved a wasted day :-)

375/5000 Maybe it was a combination of different problems. Cold joints, dirty contacts in the cartridge or a dirty power button (and you "cleaned" it by turning the console on and off 200 times), sometimes it happens that they get dirty and do not conduct the proper current. You could try to lightly tap the console or better yet, the pcb with a pencil to see if it has any false contact

Without schematic, how do you know which voltage should be where?

I LOVE your videos. Find myself shouting at my mobile saying do this and do that, even though I know only a quarter of what you do. My wife laughs at me. 😂 😂 😂 😂 I'm half way through this one. Gonna watch the rest now! 😊

I found an adapter that lets you use atari jag controllers on pc via usb. I think you have a pal jaguar... you have a ntsc tv?

[@KorAllRBare]

***Addendum*** If you find out what channel and what Format the RF Box outputs you could set another Device to the same channel and then Tune the TV to it, then plug in the Jaguar and tune the "IF Pot" "the one that you screwed" Not stuffed up mind you - Just TUNED to another channel" So it displays also at that channel.. Just bare in mind that "StillCloser" Below is correct about the various formats and having said that it may be easy to actually change some components to your Jaguars RF Box to output your regions Pal.. of course you will need to open up an RF box with your region to copy from..

Cheers for the tips Koala :-)

I've never heard of this console. Anyway, intermittent errors makes me think of bad joints, dirty contacts and/or heat problems. The cartridge connector looked suspicious indeed. There might be a lifted trace or something there, or some flux residue, as discussed. The seller also wrote something about flux residue, I think. Flux and liquid residue can be conductive, so when I see that I'm thinking it's always a good idea to clean it off straight away. The hot chip is also suspicious. Even if it's supposed to get warm, adding a heat sink could prolong its life. Oh, and it's probably best not to put solder on connector pins since you can never get it off again.

Thank you mentioned my home country man ;) Belgium is awesome :p

[@PlanetRuncorn]

Why do you call the Circuit Board Tracks "Viers" i have heard you say it a few times and and i need to know ! ...

[@Mymatevince]

Vias are the holes that go from one side of the board to the other, so a track (trace) will end on a via, travel through the via to the other side (or another layer in the board) and then continue onwards :-)

[@PlanetRuncorn]

@@Mymatevince , thanks Vince, i know know what you mean, the holes that just go from one side to the other we call it through hole plating, . cheers and keep up the good work #

Makes me want to try out at fixing mine again after sitting in with my old school consoles for 20 years. Someone put a wrong power supply in it, blowing the internals around the port

[@custardo]

UK is PAL I, Mainland Europe (excl. France) and Australia are PAL B/G. This is indeed probably an European machine. If you connect this jaguar to a TV that only supports PAL I, then even if you'd get an picture you wouldn't get audio.

The problem was the dirty/corroded cartridge connector. Had same problem with my n64. Sometimes game works perfectly when you have the pins lined, if not its black screen.

[@CJ-rf9jm]

For the 1st couple years the jaguar did come with that game included. Forgot exactly when but they did eventually sell the system without it at a discount. Got my jaguar new n still have it, even played that game a fair bit. the keypad had notches on the edges for a plastic overlay for selecting weapons n such ingame. You can probably look them up online.

[@brianpack2332]

Wow! Reeeeeeeeeeeeeeeeeeeally felt your pain on this video

[@VioletDragonsProjects]

Had the exact same thing years ago with VHS recorders. Try manual tuning instead of automatic tuning.

[@JuicyJakeRepairs]

haha i love how it decided to just start working for a bit

[@GORF_EMPIRE]

The Jaguar controller will work in the Atari Falcon030 if you are lucky enough to have one of those. That is one of the first units made..... I can see you even have the analog to digital chips but they were never used so unless you write your own game that uses them... those caps across the RAM chips could indeed be original bodge connections. Keep in mind you are dealing with a multi layer PCB and whomever was in there could have damaged the board layers. The problem is certainly with the cart connections. They are not self cleaning either. Just so you understand that. definitely replace those logic chips that were overheating. I'm sure they are damaged at this point. Use the edge of a defunct credit card with an old clean t-shirt dipped in contact cleaner. Shove it in and out carefully. Cut a strip of that old card to fit in the smaller area of the keyed connector and do the same. Make sure you clean the cartridge edge connector thoughly. I'm typing these as I watch so if you solved it already, at least keep this in mind for future reference. IPA is never the best thing to use to clean any metal surfaces. It's corrosive.... De-ox spray is the best.
