Bob: I am trying to get a hold of Samsung Canada to see if they can sort this out. It is defiantly a TXE1790 that has a K1 chassis in it. It uses a I/C 601 ( TDA7056) as the audio out and it has a Q601 (a type TO220 transistor) sitting beside it. I found out today why I had a short, there was at one time a resistor there and the factory took out and put in a jumper wire. I found the transistor that I was missing and am now waiting for I/C. The number of the transistor I don't at this time. But I wanted schematic as I have a couple of runs burned and I want to know what caused them. I will let you know when I get more info on this. Thanks for interest.
