LG TV (model #: LG 47LW6500-UA) stopped working one night, since then no audio and no picture, just black screen, however the blue light on the bottom right corner turns on when the TV is powered on.

No audio, no picture, just black screen with blue light located on the right bottom of the TV turns on when the TV is turned on. Do you think it may be because of the bad pcb (power control board) or it could be some other issues?

I have the same issue on an LG TV. The TV Guide is completely black with a small picture in the corner. It's as if the software is no longer working.

Unplug the unit and remove the board cover. The fuses are soldered in but can be changed with a soldering iron. They are glass and easily spotted on the board.

For the cheap guy like me who will probably do more harm than good:
Also check for the F3 Fuse on that same main input board. It is located in the upper right corner. Hard wired fuses; very small. You will see F1-F4 (F4 is empty). You can solder a replacement fuse right over it. I would recommend piggybacking the fuse with a fuse you can replace. Will need the holder and a new fuse. 6 bucks.
Doesn't solve problem, but I can go another 2 1/2 years and the wife won't blame me for screwing up the TV in the first place.

Ive got a LG 55" LED tv model #55LA6200 it will turn on and show the LG screen then goes black after a few seconds. Audio works and i can see the screen with flashlight which part do i need.

This could be the power supply at 55 dollars or the LED back light strips that are about 80. Unless you know how to test them, it is a toss up. Most of the time it is the led strips though. http://www.shopjimmy.com/lg/55la6200-ua
