Hello..Toshiba 51HC85, 2005 model. Turn on TV and verticle wavy lines appear until TV is warmed up completely. After warm up the picture is great again. Any ideas?


I've had the same problem for about the last 6 months. My workaround which was to leave the tv on 24 7 and just turn off the TWC service box. But now the symptoms are vertical dark lines going all the way across screen. My guess is that it will cost more to fix than worth it. I paid @$2000 for it new in 2004. Technology has gotten better so I may just go out and get a Samsumg for considerably less and be way better off. None of Toshiba's products had done well for me. 2 laptops, 3 tvs, etc. have taught me this.

Lines on my toshiba model 46h84 projection tv has lines on screen until it warms up What could be causing thi. Once it warms up the picture is fine. which takes about 10 minutes


I have the same issue with mine which started a couple of months ago and has only gotten worse. I've been googling this and found that it could be the convergence module(s), apparently there are 1-3 of them and ALL of them should be replaced. I'm not sure on a cost, but I'm guessing it won't be cheap. I think we are just going to get a new tv, with the prices for LCD's coming down this will probably be a cheaper option. Good Luck :)

Possible bad solder connections in convergence circuit or vertical deflection circuit. This happens in alot of equipment. After warm up, expansion of joint pulls connections loose. Recommend not running like this, could cause component failure.

Very wavy picture- gets worse when show has fast-cuts


First thing Do not beleive peeps about a bad card. Modules are not used in TV sets any more unles your talking about a complete board change out for a Zenith TV set. Toshiba sets do not have a card or board changeout!.. These peeps are crooks! A Toshiba set is repaired to componet level. It sounds like you may have a convergence problem or a problem inj the power supply involving the filter or couping capacitors. Seek out a pro whos an authorized servicer for Toshiba.

Wavy picture


this is caused by a bad convergence module, and there are probably some dried out electrolytic caps in the circuit as well. i have one in the shop right now that came in with the same problem. if you have it serviced, make sure they replace all of the convergence modules (there are usually 2, but sometimes 3 of them), because if one went bad the other(s) is likely to go out soon as well.
