Try pulling the plug and return it after 1 minute. TVs may have different sound-out methods, say to external home theater that you may not have, and it may have been set to this by some error.

Side buttons not working


Hard to say, but the simplest would be the "button board" upon which all the buttons are attached. It's a small board about 7" long and 1" wide if my memory is correct. However, finding it is a major problem. I doubt it can be bought.

Another thing is it could be the controller board that is bad. that would be even harder to change, more expensive, and harder to find. I'd take it to a good dealer and let them try to fix it.

The picture on my lg tv has gone dark. Every button on the remote is working except the menu button.The button on the side for menu is not working either.


Check and repair the remote control. It sounds that it need cleaning. But lack of brightness to a Plasma screen might be to a faulty Z Sustain board. Check this for more details about the TV fualts, and to how to repair and clean a remote control.

My hyundai plasma turns on, but has no sound or picture. It's a 2006, Model E420D.


Power supply is likely but if master power and not just the regular on off has to be used set is having a control problem. Power supply would be first place to look---even if green light remains no sound might mean control (main board) or power supply issue.

My t.v. cannot regulate the sound. all the buttons on the right side of the set do not work at all, but my cable control can only adjust sound but the sound, at its maximum, is barely audible. HELP ME!!


Try with your remote control. If the TV control buttons not
pushed for a long time the switches develop this problem.

Try operating the buttons. Some times it may function.
