This is the set that uses the STR3035 IC for regulation, and I have basically determined that the chip's output (pin 4) is basically shorted to ground, i.e. it has only 0.79V to ground. I know the short isn't coming from the STR3035 because I actually snipped the pin 4 lead going to the pcb, and there is still a short (about 1 ohm to ground) from the pcb.
It would be a nightmare to trace all the connections, and I was wondering if anyone out there can send me a schematic to speed up my troubleshooting. So basically, if I plug into mains, the relay fires up, and then nothing happens except after about 10 seconds, you smell the very hot 220 ohm, 20W resistors heating up rapidly. My suspicion is that some transistor is toast, but I don't have a clue which one. There is no sign of burnt marks anywhere. According to the previous owner, the TV just decided to shut itself down one day.....
Schematic or any ideas, anyone?
Thanks, Richard
