SOURCE: Plasma Screen not working only sound

It might be one of the power supplies. There are three in this model. One for the sound, one for the video, and one for the computer components. The video power supply is probably shot. They cost about $200 a peice from LG. If there was a "pop" sound when the video stoped, then it might be one of the circuit boards in the back. Yet again, they are three, each costing around $200 from LG.

My 42" hd Sanyo flat


chances are your backlight inverter circuit has failed, repaired one a few months back with the same problem. To verify this, take the tv in a dark room. plug it in and take a bright\ flash light and shine it on the screen. turn the set on, you should see either the screen saver or video from your source. If this is the case, your inverter is at fault. Depending on your model, your backlight inverter is built onto your power supply board so you will have to replace the power supply/inverter board. Not hard to do, you can do it yourself with care.

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.
