demo of inverter replacement..
First make sure to hit the menu button on the TV's remote while the screen is black, and if you have sound, and nothing is there then friend while the set is on turn a bright flashlight on and shine at angle into the set push the TV menu button if you can see a image then your back light is not working. You can also check the transformers they are close to were the wires plug into the panel, make sure all transformers read the same amount of resistance if not you have found a bad one. Now you will have to check to see if the power supply is sending 24v to the back light, if not the power supply is bad. Cost back lights around 150.00 and power supplies around 100.00. Well this should help you friend.

It's not black. It begins to scramble until it most of the screen is gone. There is perfect sound during the whole period. I've checked the cables. I've unplugged everyting. sometimes four hours it works perfectly. Then it will begin to scramble consisitently for a long period. It's two months old. A bad tv?
WOW THIS IS VERY NEW,, WELL IF IT DOES THIS WITH A DVD PLAYER GOING TO IT,, THEN IT HAS A BAD t-CONN BOARD,,,YOU SHOULD RETURN BEFORE 90DAYS ARE UP
Please let me know if you want to try this yourself, or if there is anything else I can do for you!
