TV sometimes turns on, other times it only has a blue LED, if it turns on and after it heats up it doesn't turn on until it cools down. I removed the power supply and sometimes it didn't arm after switching from 5v to power on. It stayed at 5v and none of the other voltages appeared... | Check r609, r623 and the others in this pfc line. Mine was changed from 750k to 780k, I changed it and it was back to normal. | J&M | |
