Thinking of recapping a old TV

Just because I work on CRT TV's does not mean you should. I took a electrician course for working on everything from CRT's to transformers and have both the skills and tools to work on something like this. A CRT TV can and will kill you if you don't know what you’re doing.


Now that we got that out of the way.
I have an Über high end TV from 1982 that I fixed up to play old games on.
But there are a few things I have not done to it yet. One is replace/recharge the tube and the other is to replace all the capacitors.
Right now I have it (most likely) at 90ish% of its original picture quality in B&W and about 80% in color.
I'm not all too knowledgeable with older CRT TV like this one. If it was a later CRT monitor or arcade monitor I would have it working like new.

SHORT VERSION:
The color red is over driven and the TV is from 1982. Would you replace all the capacitors on the IC board?






LONG VERSION:

The color red is over driven and I have to lower the color to keep in line. I believe this would mean that red it being over driven (too high of voltage) not knowing what voltage it needs I can't do much to fix it.:bang head That or a bad tube witch I can't see do to its already amazing picture quality. I do not have a tube tester so I can't test it right now. (Last one broke) The picture is also a tick fuzzy.
I rebuilt the neck board which helped a lot. I have also tuned everything I can tune. Now my thoughts are to replace the caps seeing as the tv is from 1982 :shock:

Safety 110% aside (I have worked a quite a few CRT monitors) would recapping it be worth the trouble?
The TV's IC board has quite a few caps on it. My only problems are all the wires on the board. There is like 100 wires and I would have to remove and label all of them :escape:

I have never dealt with a TV with so many caps before or one this old. I mostly work on CRT monitors and arcade monitor which are not quite the same. So I don't really know if replacing the capacitors would be of any help and not having a working tube tester does not help ether.

What would you do? Recap it? Deal with the red being over driven? If I lower the color red gets inline but then I have washed out color. It is not really that bad until there is a lot of red on the screen. For example when I'm playing virtua fighter 2, the level with Jacky has a red hazy overcast and sometime Kage glows red.






This old TV is kind of scary; it's not like anything newer. It even has a warning label on it saying that you need to wear a lead vest when working on it :shock: That would explain the fuzzy feeling I get when working on it :rofl:
Of course I have no problem working on it, I just have to be extra careful. It has a warning on it that say the flyback can hold as much as 200kv at 100amps.

No, but it's built like one. It's all modular and whatnot. Almost no soldered wires and separate boards.
Form what I can find on the TV, it's some sort of special limited edition zenith TV base on the advance system 3 space phone.
It has closed captioning, multiple inputs (all RF) you can save 2 color settings,block channels. Even answer the phone and use the remote as a microphone.
You can even have 6 antennas hooked up to it at once and somehow it can revive a single from all 6 at once. No clue how that works. It might just display the strongest single or something.

Looking forward to were this might go, hopefully not to the hospital, but I want pictures of this monstrosity, it reminds me of my old Mitsubishi 54" projection TV, that thing was a beast, and a great picture I couldn't find anyone that could get tubes for it, had to junk it, took up too much space. Wish I had it still though.

I'm still on the fence for recapping it. I know it needs done, but I could kill the TV and I don't want that. But the bad caps could kill the TV too

that is COOL!!!!!

If you think that is cool wait until you hear this.

The tv has a lot of room inside it, and I put a water cooled 775 system in it :shock: :drool:
Well I sold the system as I never used it. :eh?: It was so cool having a smart TV form 1982 tho. I used the speaker grill as a filtered air intake haha.
I still regret cutting a hole in the back for the rad. But it just a piece of particle board.

I find it odd that you could not get tubes for a Mitsubishi projection TV. Those kind of tv's were everywhere for a wile. In fact you can get that kind of TV for free around were I live.

As for the hospital, not happening. I would end up in the morgue if I made a mistake. If not a pile of black dust.
I did some looking into it and the 200kv at 100amps rating is likely right.

Your probably right about being able to find tubes for it, but the only guy I could find to work on it in town said he couldn't locate them, I probably got tired of waiting for updates from the guy and stopped tryin to get it fixed, was a lot goin on in life at that time. If I only knew then what I know now as they say.
