Please help!! I bought this TV last month from homecinematv.co.uk and i love it. However, on Sunday I was watching a film on Sky and noticed loads of red dots on the picture, just flashing all over the screen. Turned it on yesterday and watched a dvd - no problems until 1/2 hour then the dots all over the place. What could it be? and have I got a bad TV? Will I be able to send it back? I am extremely concerned and any help on what these dots could be woud be very welcomed.
