Question about LG 42LG70 42 in. LCD HDTV
I've been having this problem for a while now. Sometimes I will turn on the tV and the led comes on red then it changes to blue and all the picture disappears. The only solution is to turn it off and back on again.
Sometimes I get no picture but get audio.
You will have to do some detective work here. If you are getting audio but no video then
the next time this happens take a strong flashlight and hold it against the LCD screen.
Look closely around the edge of the flashlight and see if you can see an image.
If you see an image then the problem will probably be in the inverter board or the power supply board to it.
