Question about Toshiba 42H81 42" Rear Projection Television

Wavey Picture I have had my Toshiba for about 5 years, when I turn it on the screen is all wavey and it takes about 15 minutes to get a clear picture. I am just wondering if anyone has had this problem, is it worth trying to get it repaired and is it a costly repair?

My tv showed wavy tight lines til it warmed up, then became more and more clear. Over 3 mos. it took longer and longer. Today after 2 hours, It is still jumpy, w/ small sharp waves. Any ideas? If it will cost 3-400. I feel like getting a flat plasma.???

The hyper or scan converter module is bad in this set. You can certainly have this set repaired and will run about 275 to 350 depending on where and who does the repair. Good Luck

I have a toshiba big screen with three bulbs and the picture has wavey lines on the screen. Does this mean tubes are going out?

Most of these Toshiba sets have a "hyper board" that processes all the signal and a lot of them are going bad---lots of surface mounted filter caps on the board dry out and usually it begins that lines in the picture and after several minutes the problem slowly clears up and or goes away---as time goes on it takes longer and longer for it to go away----For most of these sets the only way to repair is remove the board and send it out for rebuild--rebuild of the board and labor may be more then the TV set is worth.

Wavey lines

Sounds like your set has dried caps in the Power Supply, take it to a decent tech, its not something you should try to do yourself as dangerous voltages can still be present evn if the set is unplugged.

Toshiba 57HX81 is all wiggly and distorted (youtube video attached)

I don't know about that. Someone probably was rough with it and messed them up. You should have a technician look at it.

Wavey picture

Zebra19. This problem is a common occurance in these sets. So common that there is a service bulliteen to service centers on it. Fixing it is not easy though. It ivolves 11 very very small micro capacitors. on what is known as the hypermodule. In an ideal world replacing the hypermodule is the best course of action. but.. these are almost impossible to find. if you are very good at soldering and have a lighted magnifer and very small twezzers it can be fixed. but if you damage the board....... i have done this repair about 6 times.. replacing them is what need to happen. 11 10 microfard surface caps

this is the hypermodule ... it is a board in a sheilded can that plugs in behind the input termals in the back. kind hard to get too. the caps are the small circular components that you see with the red and black marks on it.
