Question about Televison & Video
Tv has sound but no picture, tried dvd cumes up but very faint and red but no sound
First check its main power supply regualtor board's output voltages. If any of these multiple voltages become low than normal, this type of fault can occur. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electric shock. Instead, contact any experienced service technician, or the nearest service center.

SOURCE: No picture, sound ok
I have a similar issue. Sometimes the entire screen goes black and sometimes only one-half - either the top or bottom half goes black. The only solution we have found is to gently tap the TV (usually the front side) and the picture will come back for awhile. It almost seems heat related as it only goes out after the first 10 minutes of use. There must be a fix to this.

When you tune to a station and get sound I presume the screen is black so do the following.
Place a bright flashlight against the screen. Look for an image around the edge of the flashlight.
If you see an image the problem is probably one of three causes.
1) Power to the inverter board is bad.
2) Inverter board has failed.
3) The CCFT(cold cathode fluorescent light) are dead.
Someone knowledgeable in electronics can diagnosis it.

Unfortunately, what you're describing is a repair issue. You won't be able to address the problem with troubleshooting. There is a part inside the TV that needs to be replaced. If you're under warranty, this will cost you nothing. If you're not under warranty the cost will likely be a minimum of $200 parts and labor. However, be warned that the cost could be considerably higher.

1* Select any channel on the TV.
2* Point your Sky+ remote control away from the TV and press the tv button.
3* Press and hold down the Select and red buttons simultaneously on the Sky+ remote control until the red light at the top of the Sky+ remote control flashes twice.
4. Input the 3 digit number from the Sky+ remote control codes then press the Select button. The red light at the top of the Sky+ remote control should flash twice.
5* Point the Sky+ remote control at the TV and try the volume button.
If this works try the other TV functions.
If these work then the correct code has been selected.
It's important to note that not all TV functions will be supported by the Sky+ remote control e.g. Picture in Picture.
If all functions do not work correctly, then repeat steps 1 - 3 and work through all the relevant 3 digit numbers from the Sky+ remote control codes, until you find the code which supports all or as many of the TV functions as possible.
