I have a Sharp LCD TV and just recently when I switch the TV on, no picture comes up, only sound, the screen is completely blank. I have found that if I switch the TV off at the mains and leave it for a few seconds, when I turn the TV back on, the TV picture is there, but now it is gradually getting worse and it takes more than 2 or 3 attempts at doing this to finally get a picture on the TV.
Does anyone know what might be the problem here? Please help!
