Very common problem with these set. toshiba issued a repair instruction for this. the bad news is its not an easy fix. what is happing is falure of what is called the hypermodule. ideally it wouldbe best to replace this curciut board ....BUT this is not available. the next thing is what we do at our shop. we repair the board very difficult) it involves replaceing 11 micro caps. very difficult soldering and you can damage the booard.. it can be done just get sombody good who done it beforemy shop charges about 200 because of the labor involved
