Your friend is probably right. It will either be the Y-sustain brd or the Z-sustain brd. I have seen both bad at one time or another, The part numbers are on the boards.

Green light flashes 6 times then goes to standby no picture or sound


This happened to me with a TOSHIBA Regza 42" flat panel. I spent $180 dollars to have the TV taken off the wall, transported to the authorized TV repair shop to have them tell me it only required a firmware update!

I suggest you go to the LG support page, plug in your model # and instructions on updating firmware to that TV.

Good luck!

NO PICTURE THROUGH THE COMPONANT INPUT ,WHILE PLAING XBOX, ALL SHUT DOWN EXCEPT THE SOUND


The Green connector maybe cracked internally. Wiggle the connector a bit while playing Halo and see if the picture snaps on and off.

Plasma on standby


Unplug the unit and let it sit for a minute. When you plug the unit in and try to power it is there any change in the light? Does it go green and back to red or just stay red?
