Lg plasma t.v. has sound, but no picture


That usually indicates that the power section driver board (one of them) has failed on you.There are three boards each of which can fail and cause this. Usually it is the Y or Z board.

Bad news is to know which one you need to be able to test inside the tv. Good news is the boards are fairly cheap around $35. So you probably will have to take it to a repair shop to get it fixed. Unless they really try to do a number on you as far as prices it is worth fixing. However be a bit cautious here and get and estimate and find the price of a new tv. If the markup on the parts and the labor gets close to the new tv cost then you will need to decide if it is worth fxing or replacing. Ie used tv or new tv with warrenty.

42 inch flat screen shows black screen with sound only no picture


That sounds like the backlight system or its powersupply has failed. If you can see an ghost like image when close and at an angle near the dge (depends on the light) then this confirms the backlight being the problem.

Repair cost should be about $100. You should be able to get this fixed under warrenty if you have any. If not get repair estimates before doing anything. It should be worth fixing but it never hurts to know if it is getting close to what a new replacment tv is worth.
