Great repair. At one time Gateway had a tool on their service discs to write the splash screen file. I recall reversing the file structure to make humorous splash screens back in the day.

[@vincei4252]

Excellent repair and "never give up" attitude. Also your audio is excellent!

[@bansci]

Great fix as always! You give me confidence to attack complex systems like motherboards, I might have written this off once I realised it wasn't the PSU or the easily swappable components...

[@sjn7220]

Epic troubleshooting and repair!

[@ecurepair]

Thanks for the video. Nice to see some video tear-down on these popping up. I've been wanting to change mine to a sshd but never get the time to sit down and try and get it done. If you do yours, I hope you make it a video.

[@mlefe09]

Great repair! In the models that came after (7054, for example) the bios is a special one: it was good to learn that you didn't had to swap them ;)

[@HarblesTheSkeptial]

A very pragmatic approach to repair. You're the best.

[@homemdosaco2000]

I have one of those. The sata cap is bulged, waiting for the new one in the mail. Congratulations for the repair.

[@TheDefpom]

Nice work, I would fully recap the original motherboard and see if that brings it back to life.

[@jeffcandy2479]

Wow. That was extremely impressive!

[@fabiocattaneo6176]

Great analisys and repair.... As usual!

[@jonnafry]

It put up a fight but tenacity won the day! Great result with ultimately better performance.

Nice, I love saving these old Tek scopes. They are still useful and better than becoming ewaste.

[@lucvanhove9639]

Smart way of trouble shooting. 👍👍👍👍👍

[@brendanbarbour8568]

Great work. And a great addition to the lab.

I always enjoy your videos.

[@bubblehead78]

Another outstanding video. You've been online for over 7.5 years (as of Nov 2021), yet you have only 10.4k subscribers. This is a crime! You deserve many, many more subs and views. What can we do to correct this situation?

[@MOHAMED-qh3px]

Great job thank you 🌹🌹

[@artursmihelsons415]

Nice rising from death.. Good idea to backup hard drive! Intel Desktop board inside was a surprise. For old dead board - I, usually, start with CPU power phase transistors measurement when power supply goes into protection mode.. By symptoms, looks like ground side mosfets is shorted to ground (This is good scenario, because, when positive side blows out, CPU, usually, dies from direct 12V power)..

[@andymouse]

Awesome !

[@AA-en8gw]

Any chance that you may go back to the old motherboard and extensively clean it with alcohol? It does not make sense but it worth a try maybe!

[@astalavistatomi]

Nice, this was actually pc repair :)

[@ashpowell9451]

Great job

[@pgperkos]

Great video! So the fault is on the PC board, I can see it has a buzzer, so if was one of the components the little speaker would indicate if RAM or CPU is bad but the fact that it shuts down instantly resembles a short. These caps close to the Vcore... oh, God I hate these things.

[@RixtronixLAB]

Nice video, thanks :)

[@fjs1111]

Did you run a POST Code test using a card or checking LEDs on that initial board? It might be related to the BIOS rom

[@VintageSupportServices]

Can you desolder the bios on the original motherboard and dump its contents? Id like a copy.

[@fixthetempo7276]

For desoldering huge components with big ground areas like this USB connectors i recommend use the Rose metal. It's melting point about only 95 celsius and using completely reduces overall temperatures and make desoldering much more easier.

[@AnonymousRepair]

Nice repair, Try starting the old motherboard without the p4 plug (4pin connector) closes to the cpu, if it stays on it would indicate a fault on the CPU mosfets, The RAM is DDR 1 not DDR 2, Those boards do have a lot of faulty caps, Old AMD fan should work as an replacement fan they are thinner fans. Great repair video👍👍👍👍 for dual DDR it needs to be in the two white slots

[@feedback-loop]

Yes, DDR (without a number, but often mentioned with frequency like DDR266, DDR333 or DDR400). I don't think I said DDR2. I know about the proper slots for dual channel configuration, thanks.

[@AnonymousRepair]

@@feedback-loop DDR266 DDR 333 DDR400 is all DDR1

[@feedback-loop]

@@AnonymousRepair It is called DDR1 retroactively. At that time, before DDR2, there was no number at all. It was called just DDR or with frequency appended.

[@AnonymousRepair]

@@feedback-loop correct these days everybody calls it DDR1 😂

[@KuntalGhosh]

if the software works with windows 2000 it should work with windows xp as well , so u could have just cut the io shield and upgraded this to a 775 motherboard , those are much cheaper , newer and more reliable than 487 boards. i had so many 487 boards die after 10yrs of use but 775s are going strong even after 13yrs. a core 2 duo or quad would be nice and unnecessary upgrade for this

[@СергейХаритонов-к5й]

Прикольно. У меня плата немного другая. Кондеры по питанию проца вздутые были, но не все. И по питанию рядом с северным мостом один. Видимо производитель этой платы экономил.

[@mariodistefano2973]

Uau! what a repair! congratulations!!!! Another example that a bit of luck is always needed in any activity and even in life!!! If I were you, I would have been TERRIFIED at the moment the system was asking for drivers... Cloning the HDD is A MUST to recover this simply fantastic machine in case of another fault in the future. Do you think an SSD could do a better job?

[@owenaero]

what kind of motherboard did you get

[@feedback-loop]

it is marked Intel D865GLC / D865PESO / D865PCD / D865PCK

[@geirendre]

To bad these old oscilloscopes depends on an old outdated OS to work. Will it Even accept to boot from SATA without additional drivers?

[@AALONSO1962]

Thanks In Advance...!!! ;)

[@amirb715]

on the original board, replace the ADP chip. I repaired the Intel board in my Lecroy Wavepro (it was a very similar board to this with a very similar 4 phase VRM chip but different part number) and the chip was dead as in yours. I had to buy it on ebay from china but it worked.

[@feedback-loop]

I have already placed an order

[@SoddingaboutSi]

Great recovery for a nice old scope. Not keen on Microsoft run test equipment.

[@muratdagc6230]

Is the shure slx there for repair? :)

[@feedback-loop]

And this one about a handheld transmitter as well. It says PGX, but it uses the same board as SLX (just LCD display is not installed) kzbin.info/www/bejne/Y3Kzk3yVnbiZoqM

[@worroSfOretsevraH]

How does the scope communicate with the PC? Through a PCI card?

[@stevelupton2533]

PCI - have a look at 3:28. It's not a card as such - the whole main board of the scope mates directly with the PCI socket on the motherboard.

[@SidneyCritic]

Coincidently I've got 4 dead motherboards here I'm trying to repair - lol -. If it's SATA 1 it's only going to be 150, not much faster than PATA 133, and most vids I've seen don't show much improvement with a SSD. If you see a difference I would like to know, because I would like to SSD my old 478 Pentium - I think it also needs caps because it doesn't start sometimes. lol =

[@RambozoClown]

I have seen night and day differences by changing to SSD in a bunch of really old machines. Even if the throughput is not much different, the seek time or lack thereof makes a huge difference in booting up the OS where you are reading hundreds of small files. Most of the machines I've done this on are industrial computers for CNC machines, so once loaded the disc is not used much.

[@SidneyCritic]

@@RambozoClown Are these PATA IDE or SATA1, or something better. It's hard to find actual results of before and after, but I remember Defpom doing one and he said it wasn't much better. I guess I can get a SATA2 to PCI card and SSD it.

[@RambozoClown]

@@SidneyCritic I've used a mixture of PATA and SATA1 even some slow SATA to IDE converter boards. While the data transfer speeds have been the same or worse when moving large files, the time to boot Windows NT or 2000 is often cut in half or better. It all depends on what your workload is.

[@davidstech1445]

It all comes down to file size and latency for the HDD -> SSD conversions. Just about all of my computers (and some test equipment, looking at you, 16702B) have been converted over to SSD, and the speed difference is incredible. Loading an OS, especially an old NT-based one has many small files scattered across the disk that the head in the HDD has to seek and read. SSDs do not have this problem, and that is arguably the biggest speed increase. I've never really run a benchmark across the different storage mediums and data transfer speeds, but I would say everything is better overall, with the most gains seen in random read/writes, which is very common, and lesser gains in sequential read/writes as the head does not have to move very far in the HDD.

[@SidneyCritic]

@@davidstech1445 I don't really need the exact numbers, just that it feels considerably quicker, ie, faster boot, more responsive. I've done SATA2 SSD and it's a massive improvement, but no SATA1, so I'll have to defer to your experience with PATA SATA1.

[@heinrichhein2605]

If you can make a video about the cloning would be amazing, i could not find any satisfactory help online, of cloning bootable HDD. Thanks for the amazing Video! Love your attitude. I would have probably drilled out the rivets of the bracket ;)

[@feedback-loop]

I prefer less invasive approach if possible.

[@heinrichhein2605]

@@feedback-loop true, but changing the motherboard is also ;)

[@t1d100]

Nice repair. "Any testing is better than no testing." Agreed. Yep, always recap, as maintenance, since you have the device open.

[@soulrobotics]

yeah clone it! great job!

[@pa4tim]

You can buy an assortment of 5 different size desoldertips for the Sx100. They are all very usable sizes and for 99% of the time they cover everything you need

[@feedback-loop]

I have a few, but not that large

[@gordonwedman3179]

Very interesting repair. Re-capping that unit will keep you busy for a while. Expensive scope with Chinese power supply. I think I would complain to Tektronix. They should be including their own supply.

[@douro20]

Artesyn is of the world's top producers of power supplies. They would had not used them if they didn't make a good supply.

[@xConundrumx]

Might as wel change the CR2032 battery, it will go eventually :)

[@pav9978]

Hey, could you please tell me which driver you had to reinstall for the front pannel? my wont work and i am not sure wich driver i need

[@rvmeushaw]

was the battery in the original board any good? I have had instances in the past where a bad battery prevented the motherboard from booting.
