Hi all,
Since couple of days, at start-up, image is very bad : Dark color with Picture distortion (similar to a very bad Divx)
That appears suddenly, after a 3.5 years very good job.
what is strange, after several minutes (when TV is warm), picture go back with a good quality.
I have checked image settings (contrast, ....), looks OK.

Regarding the high selling price of this TV, it is a pity to have defect after less than 4 years!!!

I saw same concern inside the following (closed) topic, but without any feedbacks.
I have exactly same defects as seen on these pictures snapshot


Some idea?
