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.

Vizio VT470M no picture, no sound, no backlight. Power supply board looks good all voltages appear correct (24V, 5V, and 3.7V) and no "bulged" capacitors . When I unplug unit for two hours, the screen comes on normally backlight comes back up and picture is normal, but changing the channel causes it to go dead again. Bringing up menu with remote is really sluggish and when attempting factory reset, it goes black. Vizio light on the front of the TV comes on and off when pressing power button,

After pressing the power button the red standby light comes on, but when i try to operate the tv the standby light turns green and blinks about every second and nothing happens. I can hear a small click in the unit a few seconds after trying to turn it on. any suggestions

I have a Sanyo LCD-32E3 using analog, not digital. I have two remotes. The Sanyo remote turns the TV on and off. The Rogers remote changes the channels. If the Rogers is used to turn off, when the Sanyo is later used to turn on, nothing happens. This has happened before and somehow by pressing every key on both remotes, I have managed to get a picture. Not so this time. What should I do? I would be very grateful for your help. Thank you.

Wharfedale DMP82 mini hi-fi unit. It's stuck in standby. When the standby switch is pressed, the display lights up then goes back to standby. LCD display is on as the 5v line is still present. The 2 x 14v lines are at 4v and rise momentarily as does the 12v line. The standby line is 0v then rises to 2.5v when the switch is pressed. Not an easy unit to take apart and I've only managed to get the back (PSU) off. Any ideas?

My TV in question is a Magnavox, model 15MF 605T/17 LCD TV. It' was purchased new in July 2006, so it's our of warranty. All of a sudden it will not start either from the remote (the batteries are new) or when pressing the "ON " button on the front of the unit.

This unit is practically brand new, has no dust nor dings nor damage on the unit anywhere, not even a scratch, but I haven't been able to get the unit to power on. Power cord is connected.

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
