Occasionally my TV will decide to put flashing red lines on certain colours. For example I was watching a program with a blue background on it, the presenters didn't have any lines, but the show's set did. When I turn my TV off and on it fixes, but it's a pain to be turning it off and on all the time.
I have made sure that the HDMI cables (from the satellite TV box) are correctly plugged in, which they are.
