Re: Sanyo DP46841-00 No power, no lights, no picture
There's voltage regulators on the back of the analog main. On mine, one of them was getting real hot and I wasn't able to get a voltage reading from it. But then I removed a jumper, disconnecting the regulator's output from the digital main, and was then able to get a reading of 3.3v. As I'd said earlier, the CPU was shorted between 3.3v, 1.5v, and ground. The service manual for this TV is very good. I would see if any of those regulators are getting hot.
