I have a Hitachi 57F710E Rear Projection TV that was working great until 3 or 4 days ago. I came in and tried to turn it on and it was just dead. So, I unplugged it and plugged it back in. Nothing, not even the slight click that it makes when you plug it in. So, I removed the power supply board (It's a vertically mounted board, I believe model HA01312) and inspected it visually for bulged caps or burnt or overheated components, anything that didn't look right and couldn't find anything.
I noticed on the bottom of the board there was a row of solder joints with voltages printed next to them(10.5v, Gnd, Gnd, 5.6v, 5.6v, Gnd, 16.5v (not used), Audio Gnd, Audio), which are coming from the large transformer on top. I checked all of these voltages and they're all reading between 12.5 - 12.7 volts AC. I assume this isn't right.
I would really appreciate any help anyone could give me in fixing this issue. It's an old TV but it still has a great picture and I would prefer to fix it if I can.
Thanks
