The tv's green light comes on but there is no picture and no sound. When I push any buttons on the remote the only thing that shows up is the volume thing. It doesn't respond to pushing the channel buttons...


your main board has gone bad. Can be fixed, in my shop it would cost about $250. It is a real shame on the industry that these things last about 2 years or less. Hope you held on to your old crt style tv.

My tv stopped showing picture but still apperears


If the whole screen is just white light, the the LCD controller (t-con) board may have gone out. Your TV can have more than one version of the boards inside.

I have sound but no picture


There is either one of two things,
1) your florescent lamp power supply has gone bad or
2) part of your power supply has gone bad
The only last thing is that one of the florecent back light tubes has taken out all the rest of the tubes.
Can you still see some type of image when you depress the menu button?

My 40 inch toshiba 525u lcd shows a black picture when turned on. therer is voice but no picture


Look in the venting grills to see if you can see any white lights inside, if you do not, then the backlight inverter board may have gone out or the power supply feeding the inverter board may ahve gone out.
If you do see the lights inside, then the problem can be in the video processor section on the main board.

Have 42 inch LG flat screen...for about 3 years...


Take the back off with no power connected..You should have 2 invertor pcbs..one on the left and one on the right..well the side of the picture you cant see is the same side of the faulty invertor..replace this and this should solve the problem.it is the cheapest option..if not..im afraid is is a new LCD screen unless you are prepared to take it appart and replace backlight bulbs :)

Audio O/K no picture . Model Sharp LC-32SH12U. Thanks "Larry"


Check for a backlight failure by holding a flashlight on the screen at about a 30-degree angle, a couple of inches from the screen. Look at the area around the flashlight beam. If you see video, either your backlight fluorescent tubes are burned out or the inverter has gone bad. If you need tubes, search for "CCFL replacement" (CCFL = cold cathode fluorescent lamp").
