I figured out exactly what's wrong with my Toshiba CRT TV (20AF41)

I found this Toshiba CRT 20" TV on the side of the road a few years ago. It's served me well until the other day when it stopped turning on. Let's figure out what failed on this TV and get it working again.

Saving old CRT televisions and monitors has become a mild obsession for me because they aren't making new ones, and any insight into keeping them working is greatly appreciated.

[@JonnyMudMower]

They still make new ones you can order them from China

[@ForTheStyle]

​@@JonnyMudMowerThe plastic case and other components may be newly manufactured but the glass tubes are either from recycled used sets or are new old stock.

[@JonnyMudMower]

@@ForTheStyle whatever lol they have thousands of new old stock tubes and all the components and case are new so who cares , it’s a new tv with a 1 year warranty , there is people making new tubes but they aren’t available to the public or your paying big time for them .

[@kvmoore1]

Chances are these (CRT TVs/monitors) will never be made again. I wonder if any of these that are still fully functional and in good condition 20-30 years from now will be worth a lot of money because of their rarity. Just a thought.

[@rittol2365]

​@@JonnyMudMowerplease tell me where, greatly appreciated if u know

[@mrnmrn1]

While this solved the problem, there's probably still at least one fault. The voltage was sagging about -1.2V- 1V before, now it's sagging about -1V- 0.6V, which is still a lot for a 5V rail. The 5V VCC of the controller is sourced from a simple pass transistor+zener diode regulator, which is not a great performer usually. The raw 8.9V input is filtered by a 470uF 16V (C531) capacitor. I'm almost certain that C531 has high ESR, and probably undersized in capacitance. The same 8.9V rail supplies power to a 7805 as well, which is switched by a transistor, and has an other 470uF capacitor (C529) on its input, and a 1000uF on its output. The voltage sag on the AT+5V VCC rail during power-on is most likely caused by the high inrush current when the switching transistor connects the discharged 470uF capacitor to the same 8.9V rail, and the 1000uF on the output of the 7805 also contributes to the high inrush current on the 8.9V rail during power-up. I would replace C531, C529, and would also probably change the value of C531 from 470uF to at least 680uF or even 1000uF. It does not feel right to switch a completely discharged 470uF capacitor on a live, unregulated rail that is filtered only by an other 470uF. A significant amount of voltage sag is inevitable on the rail, due to the inrush current. *EDIT* correction: the voltage sag is about 0.6V after the repair, and it was like 1V before the repair. I wasn't paying attention that the 5V level is not aligned with the grid. Thanks to @Michael Thomsen for pointing this out. 56:17

[@jwhite5008]

Yes! Exactly! Not sure how Adrian missed it. Well, I'm not 100% sure if it is C531 or something else but 1V sag is most definitely NOT ok, it will likely get into clicky mode after a while. I'd say at least try checking if one of the power switching transistors is marginal as well.

[@c0rpse1]

@@jwhite5008 he was thinking of sissy hypnosis

[@rarbiart]

My bets are on C531 too.

[@russellhltn1396]

Yes, C531 is doing the heavy lifting of being the first stage filter for the switching power supply. Those usually fail first. I would double check it. And I agree the voltage sag is excessive even if the TV is still working (for now).

[@ronnybkk1]

Great vid Adrian!! Thailand was a big CRT manufacturer in this time period. I could still find brand new tubes and chassis at the electronic market back then. Now I come across some FBT and other spares from time to time. Because of the weather conditions CRT are still widely used here. LCD tend to develop issues with the polarizer after a few years, most commonly known as the "vinegar syndrome". Nothing beats a good tube, especially in all its RGB glory :-)

[@chucku00]

When dealing with old magnetic tapes (VCR, tape recorder, reel to reel) this type of problem will be getting more and more common than before : when 20 or 30 years ago (when the tapes were still recent, except for rally bad quality tapes) you have to use the equipment for several dozens of hours to get slightly dirty tapes, it now take only one faulty tape to entirely clog the heads. I think the same kind of problem can happen too with floppy disks too.

[@MicheIIePucca]

I can't get enough of these "troubleshooting" videos. Thank you!

[@paincreatesfame]

I could be studying for uni or doing my job orientation but here I am watching an hour-long video about a CRT lol I love it

[@TheStevesterX]

Holy Crap! I used to own that exact same model. Bought it back in 2000 because I wanted a set with Component Inputs (Y Pb Pr) for my PS2. God, did it make the PS2 look freaking good.

[@jastervoid]

Same, but I still have the set (and the PS2)

[@fattomandeibu]

The composite/component thing is kinda alien to me. Every TV I owned was either RF only or RF and RGB, sometimes S-Video and I've been using RGB since the Sega Mega Drive(SNES doesn't support RGB out, sadly) and Amiga days. I couldn't imagine playing PS1 or PS2 through RF(or composite, which doesn't look much better), unless you had a TV from like 1982, or a VERY(I mean like sub-£100 new) cheap portable which was RF only.

[@JaneTheDoe-id2vx]

Does it really make a huge difference compared to composite???

[@BH4x0r]

i think most analog inputs were awful on tv (like the cinch ones) because if i used a audio+tv signal to scart adapter (passive) it always looked way better for some reason

[@Jody_VE5SAR]

The VCR issue was just the icing on an excellent cake, Adrian!

[@The-truth-is-valuable.]

Reading some of the comments below, it seems that the "fix", was just a temp plaster on a problem still lingering. However, many aspects of this repair were still a valuable learning experience. Thanx Adrian.

[@BlueXonar]

Fun fact, worldwide sale of CRT televisions actually PEAKED in 2005, despite some markets being in heavy decline in favour of LCD by that time! You could still buy them in some countries past 2010. There are actually still one or two CRT manufacturers in existence, but they make equipment exclusively for airline and military purposes.

[@bitelaserkhalif]

You can still buy them "new" here New board, reconditioned tubes from monitors etc. Some even has dvb t2!

For head cleaning, we used Kim wipes (Kimtech). For everything, the Sony D2, Beta SP, and all of the random S-VHS and VHS decks. The 4x8" ones. Fold in to quarters. Perfect finger width size. Beware that you never want to move your finger up/down when cleaning heads. Modern decks have a piezo adjustment for head tracking and that can be broken by vertical movement. What I do is rotate the drum to between the heads, place my finger there, keep constant pressure, then rotate the drum a couple times. One nice thing about pro decks is that most have an RF meter or even an RF test point that you can scope to see the signal from the heads. Low signal, clogged heads or bad tracking.

[@MaCroCosmHD]

I'm having crazy flashbacks watching you work over a Micron mousepad, Adrian! I worked Tech Support at Micron in the late 90's. that mousepad was everywhere! They published many different 800 numbers so they could track where calls were coming from. When we got a call to that number, the phone display would say "Mousepad"! BTW loved your unboxing of that era Micron PC you did years ago, I've been watching ever since!

[@JeffBreyer]

I had a Sanyo of about the same vintage but it did support 480p. Component looked incredible. It really was handy to have all those inputs.

[@MarianoLu]

Those Toshiba TV's where really nice back in the day.

[@honich-eriker]

Orion only used Nichicon and Rubycon capacitors in their TV sets, VCRs and DVD players until the company went bancrupt in around 2015. So the capacitor brands weren’t Toshiba’s choice here. Although Orion was known for cheap products, their hardware quality was decent. However, I didn’t like the build quality of their remote controls and the plastics paintwork. Orion’s cases often came with scratches and impurities right out of the factories. In my Orion TV VCR combo from April 2001, some PCBs had the Matsushita [M] logo on it. Some - if not most - Orion-branded CRTs were actually built by Chunghwa in China.

[@SonicBoone56]

Orion was the 2000s equivalent of a TCL product today tbh, except way older and Japanese and making a wider variety of products.

[@SLeslie]

@@SonicBoone56 I am not sure if there was only one Orion or more. But the Orion I know is (was) a Hungarian brand founded in 1913. As far as I know they made decent quality products. After the collapse of the Soviet union, as a lot of companies, it went bankrupt in 1997 and the brand was bought by a Singaporean company group. Now the sell rebranded chinisium garbage.

[@Cherijo78]

One of the lessons I am taking from this is to always put CRTs like this on a power strip and physically switch it off. Simply being plugged in and unused is clearly creating stress on the components even though they're not doing a whole lot per se. Over time that will cause them to wear out more.

[@m1geo]

Doing this probably puts more stress on the parts, as they have to survive the inrush current into all of the caps every time...

[@jordan9610]

​@@m1geoI have a Samsung GX CRT that flickered on and off due to a brief power outage. And let me tell you guys; the noises that it made when turning off and back on were NOT pleasant! 🤣 Always use the TV's power button!

[@Tedybear315]

On the arcade games that I used to service (and still sorta do as a phone support tech for an arcade company) CRT monitor on older games does nothing but "click" or "Tick". Usually we trace that back down to a fried H.O.T. (Horizontal Output Transistor). And normally while we're in there replacing the driver transistor along with the H.O.T.- I'll recap the board at the same time. Amazing how much cleaner the picture looks afterwards.

[@michaelthomsen8771]

[@jaystephens3115]

Excellent repair, Adrian. Be aware that these Orion-made Toshibas commonly experience vertical foldover from a couple of caps close to the vertical IC/heatsink that are prone to early failure.

A great teaching of a repair video! X 2 for the VCR

[@georgecarlinismytribe]

If I remember correctly, the sharpening trick some TVs use relies on the detection of the transition from a lighter area to darker area during the image scan, and blanking the pixels in-between the transition boundary. It basically puts a fine black outline between areas of contrasting brightness and/or color.

[@andygozzo72]

? doubt it? that'd require a hell of a lot of signal processing, maybe a high frequency emphasising/boosting circuit ... that'll have the effect of sharpening edges

[@georgecarlinismytribe]

@@andygozzo72 You could be right. Wikipedia entry for 'Edge enhancement' does describe something similar to what I meant, though. There's likely several ways to achieve a similar effect.

[@button-puncher]

UGH, yeah the "cartoon" effect. I can't believe that they made a set where you couldn't turn it off. Good on Adrian for figuring out a way.

[@Wyatt_James]

What it does on this TV is finely adjusts the horizontal position of the beam, slowing it down during sharp brightness transitions. This compensates for poor bandwidth in the amplification circuitry, but tends to cause overshoot and geometry issues, especially on these Orion sets.

[@SonicBoone56]

Was this on ALL late model CRTs? I don't remember seeing it on any of the ones we had in the early 2000s.

Just because, I was also looking at the service manual and see you can press "VOL (-)MIN" (presumably the button on the front) and the #"6" key on the remote control and it should display the hours the display has been on.

[@ChasLarge]

Nice one Adrian. Re the "broken VCR", the most likely cause of the failure was due to the tape being rewound after it was last used. I suspect that machine keeps the tape laced up in FF & REW so it's always in contact with the head drum. If you played the tape then rewound it, this is effectively dragging the tape backwards across the heads which can cause oxide shedding. It was never a problem with earlier VCRs that always unlaced the tape before FF or REW modes. Some engineers I knew back when always laced up mechs were introduced, said that this was not only to keep the tape against the control track head, so the tape counter could use the pulses to count the tape position in real time, but it was suggested that this was so the heads would wear more quickly causing the customer to buy a new machine earlier - in other words, the first steps towards built in obsolescence. I think they was just paranoid myself but then cheap video recorders rang the death knell of the TV & Video repair trade.

[@Greenchrysopsaro]

[@69Dartman]

I have that exact same set I bought new back in the day. It still works and looks decent and it has low hours too. It's my last CRT TV left. Panasonic had the first semi flst screen called the GAO tube, excellent looking sets, then Sony came out with the actual flat tubes and everyone made similar sets. I live in deep outer SE Portland so I'm local to you and I have fixed TVs for years but no longer. I have a Beltron CRT rejuvinator and all kinds of tubes and tube testors stashed in my shed. I also had the Toshiba 34hfx84 crt HD sets from 2005 to about 2019. Excellent looking set and it just continued to work.

[@mrnmrn1]

Here in Europe, Thomson was very early in making almost fully flat CRT TVs. The earliest I saw was from 1990-1992. They called it Thomson Planar, came first with the ICC5 chassis that was developed at around 1986-1988. The chassis needed an add-on board with a ton of correction coils and capacitors, because the flat CRT needed quite some trickery on the deflection for proper geometry (I think it wasn't just flat, it had a deflection angle greater than 110°, maybe it was 130°). They are as flat as most late "flat" CRTs on the inside. Because most "flat" CRTs are only fully flat on the outside, the inside still has some curve. Even lower-end flat Trinitrons, they are still cylindrical on the inside. I smashed some dead flat Trinitron tubes, and the aperture grille (so the screen, too) is actually curved. Probably the Bravia / XBR Trinitrons are fully flat on the inside as well, at least that is what they claim. But my cheap KV-29FX20 from 2001 definitely had a flat Trinitron tube that is curved inside. I smashed the dead tube that came out of it after 39k hours of operation without any failure (the TV might still work, I replaced the tube in it and gave it to my neighbour in around 2010).

[@manytrickpony695]

Excellent troubleshooting skills... an oscilloscope is a tremendously useful tool.

[@zebo-the-fat]

[@drumcorpshistory]

My mom for many years owned a black flatscreen CRT that I swear was an Orion brand although i can't exactly remember because she also owned a much older Orion branded VCR and that VCR took *years* of almost daily use recording playing rewinding and both of them were super reliable, I wasn't too shocked to see the tube being Orion brand but that also means even though its towards the end of the CRT era it should be reliable for a good long time, seeing as how it didn't really get used when you found it. Great stuff as always Adrian!

[@paulstubbs7678]

Good job, as mentioned elsewhere, I'd also check/swap other caps that are feeding the regulator that supplies that 5V rail, maybe even the pass transistor is a tad low in gain.

I recently salvaged an old EMac from mid-90's from an old lady who was about to toss it. Now I am not so interested in the Mac components but it does have a really nice nearly flat shadow mask CRT. She also said it had not been used for a long time and when new it was not used much either. The machine has seen at most 100 hours of operation. I have yet to disassemble the machine, but I am expecting the CRT's Cathode to be nearly pristine. Keeping it for eternity or until it breaks, because these things are becoming exceedingly rare. If only I'd realized BEFORE I tossed a beautiful trinitron CRT (approx 10 yrs ago) with ultra fine aperture grille, how valuable they'd become. I love LCDs but CRT's gives the retro stuff a pure look like nothing else. I am hoping there's some genius little guy sitting in a little office somewhere in China or Japan working on a way to make flexible OLED displays with a bulge so they resemble CRTs in appearance.

One of the biggest problems with old tube TVs is that the line frequency oscillator breaks down the solder so first thing is always to resolder the ground tabs around the frame of the case. It uses the metal frame to give other parts of the TV a chassis ground 👍

As far as CRT TVs I think I had a simple diode problem failure but I added to the problem by cracking my bottom power board as the TV maker confused me as to extra set of screws that needed to be removed hidden at the bottom holding that board in place when trying to remove the back on a 2005 RCA CRT TV with those same number of accessory ports also for inputs and outputs to the TV.

The clogged-head syndrome reminds me of those cheap no-name VHS cassettes, where if you left it on pause for a few seconds, you could watch the picture deteriorate into snow requiring another head cleaning operation. The opposite of course being those Memo-wrecks tapes which kept the heads perfectly clean by virtue of sanding them down, including the upper (and sometimes lower) drum. I tended to use thin card on its smooth side rather than paper though and gently rock the heads back and forth to dislodge the crud from the heads without stressing them. Mind you, back then König had pretty decent "pattern" replacement video heads for around a tenner trade, which seemed just as good as the originals and lasted well. Those were the days!

Looks like the AT is having fun in the background :) I have one of these TV's.. It was a thrift store rescue. I imagine its about 20 years old. It has some of the same issues this one does. I used to play the video from my digital camera which has video output.

Adrian, Adrian, Adrian... With these old TVs, you need to wait for them to warm up before they turn on!! 😅

Nope, 2000's era TV sets turn on in less than five seconds, if they don't something has gone wrong. These TVs dont hava any other tube than the fast response CRT. BTW, if this an attempt at sarcasm, it never adjusts well in written form.

Well done ! If I still had a shop I would hire you ! LFOD !

As an European, my symathy to all US tech enthusiasts for not having scart, it makes life so much easier, scart wasn't just audio/video with everything from composit to rgb on it, it also had control bus, so componets could control each other, synchro start, channel change etc. Connector was relatively big with 2 rows of well spaced easy to solder pins, so making custom cables was pretty easy.

the YUV (component) input is quite nice to have

CRT TV sets ftw, I also still game on a crt, in fact I have 2 identical units from Bang & Olufsen (a design electronics company in Denmark) one is from 2004 and the other is from 2006… yes 2006!, the model is: BeoVision MX4200, to bad they didn’t release this tv in the USA 😢 the design is excellent.. glad you fixed yours Adrian 👍

if i'm not mistaken the last to close down the picture tube manufacturing division was the china chunghwa company.

Since the late 90s. Orion was building full chassis, not just the CRT. Almost everyone was outsourcing to Oriion to design and build their chassis for them.

[@8-bitcentral31]

Yeah with my VCR I find that sometimes a bad tape will do that. I just run a clean new self recorded tape in it for about an hour and gradually the picture comes back until it is bright and vibrant again.

If you had a tape of the episode already, why didn’t you just fast forward to the solution? 😂
