I have no picture but have audio. Problem occurs AFTER playing games on a Sony Playstation. After you get done and switch from the Input from the Playstation to Digital TV you get a blank screen. If you do not change inputs and just watch TV the problem does not occur. When this first started happening if you hit the side of the TV the picture would come back. Now its gone for good. TV is only a few years old.

After watching for about 10 to 20 minutes the tv does something weird like your'e pressing the input button. It keeps switching from tv to vidio or whatever else happens when you press the input button. When the screen keeps switching like that it just goes back and forth so your picture keeps coming on for a second and then back off. If you try to press the input button to fix it nothing happens. You just have to turn off your tv. It has its own dvd player on the bottom. I'm wondering if that

I have LG LCD TV Model No: 22LF12R. The problem is the TV fell face down when it was still powered ON. Now when you switch it on the power LED comes on but there is nothing on the screen. When you press the remote control the LED responds or it blinks and when you power off on the remote it goes off and when you power on it comes on. The problem now is there is no display on the screen. There is no voltage in the display unit. Which components shoul I change. Hope u reply soon.

I have a Gateway p46m103 flat screen television that will only turn on after plugging and unplugging the power cord many times. It would eventually turn on each time I tried this. Now, however, the green power light comes on, and I can hear it is on, but the screen is all black. I even tried pressing the Input button on the front of the television, to see if I had accidentally changed it, and even the icon on the screen will not show, to see if I am seeing the cable box, or the dvd player, etc.

My 23pf9966 doesn't recognize the HD cable input (no cable picture). I can change the channels & volume, but all channels are just snow and no sound. There is one channel that is blank, but no volume control comes on. Just a black screen. The channel seems to change, if it's the blank one and I count up 2 channels, then go back, it will be snow again. What is going on??

The tuner - the part that actually selects the channels from the signals on the cable - has failed and it will have to be replaced.\012\012\012This involves careful desoldering of the old part, the purchase of a compatible replacement and its v ... Philips 23PF9966 23 in. HD-Ready LCD Television

Remote sensor on tv not responding I,have to turn on tv manually. change input manually,tv reception is ok.
