Most projects in life are "easy",if you know how.Chassis will have to be pulled,convergence IC's replaced w/top quality parts to prevent recall.Some excellant soldering will be needed for prevent maintenance,for instance,the steel jumper wires feedig b+ to convergence IC's.

SOURCE: My toshiba 42h83 tv has sound but no picture

of course check different inputs etc to make sure something did not get disconnected.

This rear projection set uses 3 picture tubes and the set will protect them if there is a problem in the vertical or horizontal sweep circuits that might burn the screens or the damage the tubes.

No simple answer as a lot of different parts are possible for this problem.

My Toshiba 42H83 has a scrambled screen for about 5 minutes when it is turned on, if it has been off for a while. Once it warms up, it works fine. I have replaced the satellite receiver but this did not...


ok, you are talking about lines in the picture, it started where it would clear up after a few minutes but now it will slowly take longer?

I know what is wrong.

The picture is all waves ,I get sound and color but the picture is all lines and waves,what part should I get??


To fix the shaky picture on the toshiba rear projection tv model number 42h83. You need to either replace the 13 capictors on the hyper module or simply replace the hyper module itself. It's cheaper to replace the caps, but you'll need decent soldering skills to do this. You can replace the entire hyper module with less soldering skills, but I believe the module costs about $100, maybe alittle more. You can find the entire fix by googleing "hyper module". Good luck and I hope this helps
