Put the TV on a table, screen down with a blanket under it. Just remove the back cover to get at the YSUS Board. It's in the left upper corner.

The board looks like this, I removed the Heat-sink to get at the IC under it. But once you remove it you can send it in for repair.

To make a long story short originally bought the LG du-42px12x with a bad ysus board(no picture just sound) replaced the ysus now the picture and sound work great but there are colorful dots all over the...


Sounds like the y sus was blown out but what cause it. Were you careful when you were checking voltages? As long as you didn't short 2 components together, your y sus should be fine. Unless the y buffer up and/or down blew them out. Even the panel could blow it.

Basically you need a scope to adjust the ramps and everything. You can adjust VA and VS with a meter. If you don't have access to a scope, then just start changing the ramps etc by eye. It might take a little bit to get but eventually you'll get it.

How to change lamp in toshiba 42hp66?


This TV is a plasma according to the model number you've posted. It does not use a lamp.
If the plasma does not show any picture, there might be a defective Ysus, Zsus or power suppy board.
There is a high failure rate on the Ysus and Zsus boards.
Search for a Ysus and Zsus board on google and you should find them.
Good Luck.
