LG 47LX6500 backlight off after a sec. no video

[storexxm]

Hello folks.
I have another patient.
LG TV lx6500. When i turn it on the status led goes normally from red to white.
the backlight turns on for a sec then off again... after a few seconds i can hear a high pitch sound, backlight turns on and off for another sec and thats it.
No video with flashlight.. sound is working. no optical problems on the boards.
any suggestions?

Seems this patient have shorted Led ,have tried removing the LED connection from the main board and observe if the sound occurs?open circuit or connections from the power board can also cause such intermittent behaviour.

Hello storexxm
It looks like you already have added to a thread regarding this set that Budm is assisting you with. Two threads will become very confusing to anyone helping.
