You need to check the back light is still on when the screen is blank (check through the back).

If the back light is on, need to change the Powwer Board.
but,
no back light, need to change the inverter.

My lg plasma tv is cutting off the edges of the shows we are watching. I cant find a setting that will take care of it. Can you help


hmm normally these settings are found in the picture settings of the set top box or just a setting in the tv's picture settings now there might be an option to say fill screen that may work best for some or leave the tv in 16:9 some broadcasts may only be in 4:3 at times this is normal broadcasting and not much can be done unless the setting on the picture option is set to fill screen

I have sound but no picture on my tv


This is a popular question. Most of the time you either need to make sure all connections are not loose or just need to turn off your tv and receiver and unplug. Wait for 1 minute then reboot.
I recommend this short video as it walks you through some diagnostics for other possible problems.
