I have LC37D40U for 1.5 years.
Yesterday white and blue colored lines(composed from small squares) appeared all over the screen.Initially they formed stair like patterns from both sides of screen(when there is no signal) but when there is channel with video signal it is covering all the screen.
It still showing the colorful picture but covered with flickering lines
It doesn't have this problem on setup screens - no lines everything clear.
Could you please tell me what could be the reason of this problem and how expensive it will be to repair it

My 32D40U would turn on for 5-10 seconds (Please Wait would appear) and the screen would go black. Sound Normal. It would also sometimes do this after running 5-10 minutes. I read somewhere that the inverter board would come loose and lose proper ground. I took the set apart, removed the board, and cleaned up the grounding points. I reassembled using some copper paste on the ground points and LockTite on the screws. I used some contact cleaner on all the connectors going to the board. I noticed two cables that are covered with copper shield tape where too tight at their connectors and repositioned the tape to give them some slack. The problem hasn't occurred since the fix.

You must contact a svc co. This is a upper or lower buffer board problem and possibly a control board. Nothing you have done wrong, it just happened.

Sometimes when I turn the tv on there are white and blue lines on the entire screen.. The buttons on both the tv itself and the remote won't work, you have to physically unplug it for a minute or so and then turn it back on and it is fine. Sometimes the show is beneath the lines and sometimes it is just the lines. Makes me nervous as we have had this tv for only about 1.5 years.
