From the symptoms mentioned it seems that you have a problem with the LCD back lighting circuit, also called inverter circuit.
One way to confirm is to turn on the TV with the room lights out ( dark room ). From the back ventilation grill on the top of the TV you should be able to see some white light ( like a fluorescent lamp ) coming out from behind the LCD panel. If not its the inverter circuit problem. The inverter circuit provides high voltage to the cold cathode lamp array behind the LCD panel. To get to it one will have to strip the TV. You have to remove the back cover, disconnect the circuit boards and remove them and then remove the metal shield plates before you can get to the inverter board.Then you will have to get the replacement board from the authorized service center. Get professional help if you are not up to it or revert back for further instructions.

Look to see if those inputs in the on screen menu show or not---locked out maybe? Someone using just the other inputs may have disabled them.

42 inch flat screen shows black screen with sound only no picture


That sounds like the backlight system or its powersupply has failed. If you can see an ghost like image when close and at an angle near the dge (depends on the light) then this confirms the backlight being the problem.

Repair cost should be about $100. You should be able to get this fixed under warrenty if you have any. If not get repair estimates before doing anything. It should be worth fixing but it never hurts to know if it is getting close to what a new replacment tv is worth.

42 inch LG Plasma TV - Lost picture


Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.

Check the signal type. It may be set incorrectly. Change the channel. You may be on a blank channel. Check to see if the TV is tuned to channel 3 or 4 if you are watching a videotape. Check the TV/VCR button on the VCR is in the correct mode by pressing the TV/VCR button on your VCR.
