I have encountered technical problems with my TV. Its an Hitachi widescreen 28 inch bought in 2000 for £500. The picture is still fine. However the functions have started to go weird. The sound goes to full blast all by its own and doesn't respond to the mute being pressed. The other functions such as brightness, colour and sharpness all go to full when depressed on the remote. Does anyone know what the problem is as television repair outlets haven't seemed to heard of such problems. I posted a similar thred yesterday but it has since disappeared so iapologies if you had responded to that.
