First check for any loose and bad connections, check the wire.

Try first unplugging the unit from main for ten finutes.

If problem persist check cable connections, it may be a dislogged lcd ribbon cable or a defective lcd controller board.

It is very likely that the backlight bulb that provides light for the LCD is burned out, it can be replaced, it is called the LCD BACKLIGHT BULB.

This could be a solder break on the input section of the main logic board. check to see if the input socket is lose when touched. if so, it will have to be re soldered in place.

47" plasma 1080p ... screen went black , sound


Plasma TV's have a shelf life. By that I mean the screen is only good for so many hours depending on the model. Most likely, you have burnt out the screen and the set will need to be replaced. The good news is, plasma TV's used to be better than LCD but that is no longer the case. You can get a very high quality LCD TV for a very low price now. Also they use a fraction of the power and don't generate all of the heat of a plasma.I'm sure this is not what you wanted to hear but the reality is that ALL plasma TV's do this eventually, and it is something that most salesmen back in the day didn't bother to tell customers. If you have an extended warranty, you may be able to get it replaced.

LG 50PG20 Plasma,, nothing shows on screen its all black


This model was known for issues with the Y-sustain, Y-drives, and the Z-sustain boards. These boards help process the picture image to the screen.

When one or more of these boards fail, the screen stays black, and you only have audio & on/off.

You could call LG and try to get your TV repaired at a discount if you can convince LG to honor this known issue.

Another issue could be the actual panel has gone bad. The plasma panel in your TV has a two warranty and LG would fix that for free. Well…it would be free as long as it’s not past two years of your date of purchase.

What zip code are you in?

Sounds like main board failure and or power board failure. You need to contact manufacturer and describe problem for tech support. Some of the parts in Samsung TVs have lifetime warranties. Change out of two board is about an hour job and service call is usually comped. Hope this helps. J

42 inch LG Plasma TV - Lost picture


Our LG 50" plasma tv screen went black after a popping noise but still had sound, after great diliberations decided to take the back off and have a peek!
We unplugged the tv and tested the fuses (there were three we could see) one had blown, the one on the left as you look at the back of the tv it also has one above it. We wrote the code/seriel number down and took the fuse to the electrical wholesalers Maplin and bought a pack of 10 fuses for £1.29 replaced the fuse in the tv and everything now fine!!!!!!
Hope this might be of use to anyone whose lost the picture after a loud popping/snacking noise but still has sound.
