Hi everybody,
I was wondering if anyone could help me with this set,
There is a black and purple spot on the tv, as it warms up it gets worse.

Any idea??

May be a problem with diffuser film behind panel. Is that a dark spot in right hand corner?

Thanks for the answer,

No that
's a bit purple, but now there are more spots on the screen, black in the upper right corner.
After a while they vanish a little bit, but I have no idea as where to look.
Trying to get/buy a diner tv but so far no luck.

could try disconnecting one side of the t-con ribbon cables at a time and seeing if it gives you a clear pic.

weird problem though.
