Hi Guys
A friend has got one of these teles and every now and then the bottom half of the screen starts flickering and u cant see the bottom half of the picture, then it will go black.

This only happens for a minute or so and then goes away, then it could be days before it happens again, or it can happen again the next day, its very intermittent, ive searched round google but not really found anything.

has anyone got a clue guys

any thoughts really appreciated

Cheers
