Been a while since I posted here (thanks to the advice I received, mainly Very Happy ) and my old Toshiba's been behaving well on the whole, (model 2939DB) vertical I/C resoldered & no more horizontal band.

However, over the last few months it's developed a vertical foldover at the top of the screen. It started as just being less than an inch & better as the set warmed up so I'm guessing a dried up electrolytic somewhere.

The problem has progressed to the point now where its a good 3" of foldover which is pretty annoying to say the least so I thought I'd better fix it haha.

Just wondering if anyone has an idea if it will be a bad cap, or what else it could be. And whereabouts on the board should I be looking for it?

Many thanks in advance. Dan.

My thoughts yeh, thanks. It seems from my online searching that not many people have this model (or at least don't post any problems with it) so Im guessing it'll be more a case of tracing up the circuit tracks from said vert. IC & checking/replacing all the electrolytics I can find with a connection to it's tracks.

Was just looking for a "lazy" solution if someone had already traced which cap numbers, but seems not with this model...

I'll post back when I get round to fixing it with the results, which ones I replaced & how effective it was/if I get away without replacing the IC too.

Saw a mate with another problem TV earlier so I'll make another post about that if I can't find anything already about it (I have my suspicions what the problem is but we'll see

Thanks Cool
