I am hoping someone here can give me a bit of advice on the P/S from my LG rear projection TV.
A friend gave me a 60" LCD rear projection TV that did not work. He said it did work but once in a while it turned off by itself.
When I plug it in the power LED turns red and the fan comes on. When I try to turn it on, the power LED turns orange and flashes a
few times and then turns off. I hear a click in the back when the TV turns on and again when it turns off.
I had the lamp tested at a TV repair shop and it is OK. I took the TV apart to get better access to the inner workings and started looking
around for a problem.
The P/S has no bad caps on it or any burn marks. I tested the input voltage on the ballast and it has 1.9vdc coming in (from what I have
read on the net, it should be 240vdc).
How can I test the power supply properly to see if it is the problem?
Thanks,
Ian
