I have an LG 60PA5500-UG with no picture, and no sound (most of the time, I'll explain).
I've removed the back cover, and checked the three fuses in the power supply. I've also visually inspected for blown caps, but don't see any.
In line with other advice here, I've powered the unit down and restarted with only the zsus disconnected, then again with only the ysus disconnected. No change in state fit either.
Before the unit died (I think it's dead) the USB ports failed one by one. I'm down to one working (if I can ever make the tv work again). I'm thinking this is a problem with the input board. When it's plugged in, a single red led lights up on the board marked LD500 C500. Is this an error code?
Same said for powering up. It clicks on right after I apply power, and the red stand by light next to the power button comes on. However, if I press the power button, there is no click, the red standby light blinks twice, and nothing else happens. Repeated pushing of the power button does nothing.
Where do I go next?
