Question about LG 42LG70 42 in. LCD HDTV

1 Answer

Picture goes off within seconds once turned on

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.

Sony bravia kdl55hx729 3d led tv turns on 3 seconds shows picture than four red flashes


Hello,
the error light sequence that you are seeing is indicating a "backlight error". Most likely you have a bad inverter board -the board that powers up the back-lights behind the display panel. They might be available via ebay if you are a DIYer, or you need to call for sony service.
Good Luck!

No Picture no sound on a Hitachi Rear Projection


if the 120v never comes up, check e994 as it is probably open, and either the blue horizontal retrace cap infront of the h-out transistor is burnt/shorted or transistor could be.
