While the TV was playing today, The picture went black there was still sound. I shut off the TV with the remote and there is now no picture of sound the screen is black.

SOURCE: INSIGNIA TV FLAT PANEL (not LCD) cant play PS3

Check to make sure it is on either the AV 1 or AV 2 channel

SOURCE: TV was playing, then the screen turned black.

If the screen is black and you have sound then lightly press and shine a strong flashlight against the screen. If you see an image around the edge of the flashlight, an image is being 'displayed'. The problem is probably in the Inverter/CCFT or the power going to the Inverter.

SOURCE: Insignia NS-32LCD has sound but no picture -

If an LCD TV has sound but no picture do the following:

Use the source button to ensure that source is not set to the wrong input.

Try unplugging power cord for ten minutes, to ensure it is not a setting problem.

Check all the video cables at the back of TV.

Check Light /Color settings.

If problem persist and does not depend on external receiver or settings, then it is likely an internal fault.

If it has sound but no picture then one of the following parts is faulty, and must be tested and replaced:

Theinverter is the high voltage board that provides variable power to thebacklight lamp. This is the most common. When inverter is faulty youcan get no picture, or a very dim picture that can only be seen bypointing a torch light with a 45 degree angle on the LCD surface fromvery near distance.
The inverter must be tested by reading voltages with a multimeter.

The LCD ribbon cable/LCD display and connectors.
Thisis quite uncommon, but happens. If the TV had been hit or moved the LCDcable may have slipped out, or the LCD connector may be damaged.

The LCD controller board.
Thisis the board that controls the video signal, it is difficult to test,as there is need to read determined values on IC pins. To test thisboard you need to purchase a service manual and follow thetroubleshooting diagrams on service manual.

Input/Output Signal boards.
This are the boards where youconnect the video and audio cables, if a signal board is defective,then you may get no picture on particular inputs located on faultyboard.

If under warranty contact the manufacturer ringing the number on the user manual.

If you want to repair at your own expenses, just locate any good qualified repairer.

If you still have back light, then the T-con is probably defective. If you don't have back light, then you either have a bad power board/inverter or a defective panel
