LG 42LC7D Flat Screen

Oct 28, 2008

-   TV worked great from March when it was bought till the end of September, then one day screen died, green light was still on but could not get any image. Sent it to the authorized repair shop, they replaced main board. Just came home and plugged it in...not even 20 minutes and it's out again...so back to the shop.

-   We have the same problem with this TV. This is the second one we've had, the first one was taken back and replaced but the new one has developed the same problem. The TV works for a few weeks then one day when I turn it on the LED on the front turns green and the backlight comes on but there's no picture or sound. I am unable to access any of the menus or switch between inputs, it's just a blank screen. Have already tried the following:
Removing all cables and reconnecting power only 10 minutes later.
Attempting to switch between inputs, but there's no display to confirm what's happening.
Power and ariel attached only.
Nothing has helped so far. It's still under warranty so I'll be trying to get a refund on this. Is there something I'm missing, perhaps a way to reset the system?-   IgorUK
