Westinghouse 30" tv has no sound, no picture. green light is on.

TV was working fine for 4 1/2 years, then all of a sudden no picture, no sound. I unplug the power from the wall, then from the tv. wait 2 minutes. nothing. Then I remove the actual AC unit from the tv for about a minute, disconnect the power supply, then replug the AC unit to the tv then the power supply. TV works for about 3-4 minutes, then again no sound, no picture, green light.

Same as above

If it has sound but no raster or no picture it might be a back light problem, this could be worth the repair, check with your local repair shop and see what a repair of this type could run.

I have a 32" TV/DVD combo westinghouse LCD TV. When I turn the TV on I get no picture. There is sound. DVD player does not show picture either, I have sound but no picture.

This is a backlight or inverter Problem. Based on the model you have, I am guessing the inverter is defective.

Inverter is defined as the board in the TV that supplies power for the flourescent lights inside the LCD TV that provide backlighting for the TV's Display

You can also try a hard reset: Unplug TV from AC mains and remove all cables from TV. Wait about 30 minutes and replug to AC power and redo the cabling. Switch on the TV and see if it works..
