Suddenly no picture and no sound all three lights flashing


First make sure to hit the menu button on the TV's remote and if nothing is there then 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.
Cost of backlights is around 150.00 and power supplies around 100.00.

No picture but sound


First make sure to hit the menu button on the TV's remote and if 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 backlight, if not the power supply is bad. Cost backlights around 150.00 and power supplies around 100.00. Well this should help you friend.
