My 46inch sanyo lcd 46XR10F has half a screen with pitcure and the other half all black or coloured lines. I have sound.how to fix ?

SOURCE: vision 42 inches plasma tv

It sounds like there is a problem with the tuner inside the television. Your best bet is to send it in for service.

I have this fault listed in our database on this exact model, we put it down to an LCD screen fault, the TV was returned unrepaired.

New screen's are too expensive.

Sorry I'm the harbinger of doom.

I hope this helps.

The problem is that the panel has failed. Apparently this is a common problem with LCD TV's between 18 mths and 3 yrs old. If it survives over 3 yrs it is likely to last for a few years longer. The cost of replacing the panel is more than a replacement TV!

Hi there! The panel may be in protection mode. The Inverter board is the most logical area to start after checking power supply Voltages.(5,6,24 and 13Volts). There may be coils on the Inverter Board which have bad soldering or faulty. Other than this it may be main board which controls switch on or off. If all else fails, refer to a repairer. Beware of High Current!!! Best Wishes and Good Luck, Jus004

You may ahev failing T-CON board, try having a small fan blowing at the vent on the back of the TV. If you can post pictures it will help a lot.
