Are there mobile phones and other suchlike devices that can receive or broadcast as I had the same problem and it turned out to be my neighbour connected to my television via S - beam or dans. .This is a problem all over this site and others but if you can check whether the television has an open connection with another device Or if it sometimes goes away then comes back then I believe that you should be able to get it working correctly.

Tries tv unplug,replug it back like about an hour later.Go into tv menu goto PICTURE go down to do resetting.To resetting the tv Tuner signal board back to factory setting,now it should be working a gain.If still have the same result.Than the manual control PCB board like power,volume - + so on.. is short and the causes.Tries wwebsites like Shopjimmy.com,Ebay.com to buy a furbish Manual control PCB bosard for the replacement.
