That's why we want the pictures.

Check the controls on the back of the flyback. Focus and screen. I never heard of that make. Maybe TMK or XAM. LOL.

The CRT is not failing that I can tell without a tester. After adjusting everything I could think of and getting nothing I adjusted the red color and I accedently touched a wire and instant color and brightness. I thought maybe it was a ground issue and nope. Just got spark and a blank screen until I pulled it. When I let it go, right back to bad color and real dark. The more people who have the couarage to touch me while I'm touching this wire the brighter it gets. Never seen this before. I can even feel a little tingle when someone touches.

This isn't it but it is really close. Not the same "brand" .



If anyone has a schematic so I can trace this down I would really appreciate it.

Edit: Turned it back on to try it again, It bites now. could'nt get any kind of voltage reading on it either. But if I place a test lead on it and the other end on something metal it kind of brightens. Bad cap perhaps? When it would come up when I touched it, The color and brightness was great. Just needed adjusting.

Heres the pictures. Whole album.

I'm still working on it and taking pictures, She ain't done yet. It uploaded in reverse order, Begining is at the end.

Yes, this is a Toshiba. The chassis looks like a literal snapshot of my 1976 Toshiba/XAM...which is a superb set.

Your photos show loss of luminance which could be a lot of things in a set of its condition. Amazing it still functions partially. I'd at least clean out those modular connections; & reflowing the solder on them. mine's newer and cleaner and it needed this done, as well as some lytics.

[Cruiseomatic]

Modular connections? I have never seen a set like this one where it is all litteraly plug and play. If I touch that red wire next to the blue control then everything is fine. When I was touching it, It ran superb but couldnt take a pic because I was creating the "ground" for the CRT to function. What lytics should I replace? I also noticed on the underside of the PCB there was some brown crust on the edge of the solder contacts. Could that be causeing this?


Thought the wrong color. It is the blue control. Not red.

[zenith2134]

Yes, modular. Those stand-up boards mount into the bottom, mainboard. The protective cover on top needs to come off. I scrubbed them after reflowing and replacing parts, then 'defluxed' with special CRC non residue cleaner. Yes, the crustiness areas need attention.

[zenith2134]

Also, the set you linked to isn't as similar to yours, my 13" one is. There are pics here someplace.

To be clear, the actual year of your set will be somewhere around 1976 or so. This is way too modern for '68. It probably has a notice which references a law that passed in '68 which governed all sets that came after; that throws people off sometimes. I suspect this was a store brand.

[Cruiseomatic]

I've uploaded a video and two comparison pictures when I hold that wire and when I don't the difference.

Edit:'76? Thats It? Wow. Not what I was expecting. It was a trash rescue and looked like Hell when I got it. Still does to me. Has a picture problem I cant figure out, Electrically burned me number of times today, and is a 70's model. I already have a '79 Zenith with picture problems, One side is dark, other bright and letters have shaddows. I hope it is just one cap that will fix that one.

Does anyone know what I can try to fix this set?

Zenith2134, Do you know where I can get replacement knobs for this or what model or even brand this one I have is? I'm missing the power/volume knob and one of the fine tuning. Also, are the tuning knobs supposed to stick out some from the face? Mines does some. What kind of cleaner did you use on yours exactly? I've already cleaned most if not all the contacts but doesn't hurt to try something else.
Thanks.

[zenith2134]

My tuner shafts don't protrude fom the front plate at all. Theyre recessed and the knobs have a hollow post.

I'm not sure but I may have some smaller knobs (color, bright, etc) from a Sanyo metal case 1983 that might just work.

And yes, I don't think this could be from '68 and not have a tube hv rectifier.

The chassis in this TV is made by the General Corporation of Japan (later on they became Fujitsu-General). They sold TV's here in Australia under the General brand with a near identical chassis. This set was made around the 1976-78 period as the earlier chassis from 1975 was a delta gun CRT set.

From the description of the problems, I'd do what several people has said to do already and clean the module connectors. They will be dirty and corroded just like the chassis metal was and it is amazing it is working at all considering how rusty it was. Don't go worrying about what parts MIGHT be faulty until all the electrical connections have been cleaned.

[Cruiseomatic]

I have all the fine adjustment knobs. Still can't figure out the picture brightness issue. This thing is a headache now. It is'nt even fun anymore.

Edit: I pulled the boards and cleaned the contacts, problem still there. It is amazing it still worked with the condition it was in. Doing what I can to clean it up though. I didn't think I would get it as clean as it is now siting on the bench. Once I get the picture solved she'll be done with the exception of the knobs and face. Should make for a nice shop television. It isn't to special to me. Just a mid 70's Japanese set. But I still had fun with it. Someone here might like it. I have a '79 Zenith I like which is why I'm not to crazy about the set I'm currently restoring. Like having two identical cars that are the same. Kind of pointless. Not to mention I don't like the steel cabinet. Just good for being solid but electrical hazard.

[Cruiseomatic]

Got it finished. Found the brightness problem. It was a bad solder joint. Now shes nice and clean. (Internally). Still working on the face. Next is my '79 Zenith. I just hope it has as good a picture as this Japanese set does.

[zenith2134]

So it only had Toshiba CRT, tuner, and snap in modules..mine said 'TV-2' on the boards.

Either way, these are great IMO. Glad you got yours sorted out!
