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.

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. RE-align in servicer mode==final step.

You will need to trouble shoot the start up and shutdown circuits. Often this is a minor component failing causing the set to not power up or go into protective shutdown. Do you have the service manual for this TV?

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

NO picture most offten means HIGH VOLTAGE circuits are not functioning correctly.

which can be caused any myriad of factors.

such as the relay to the high voltage side.
