I've search through the forums and have only found one thread that covers this:
I have a Samsung PS42Q7H which is displaying the dreaded pink bands. Youtube and Google have turned up search results which suggest a new display wil be required, or a voltage adjustment could solve the problem. Does anyone have any experience with repairs of this nature?
Secondly, I am starting to see a lot of "cartooning" in dark scenes. The picture is great when watching a daytime HD picture, but the depth of colour suffers dramatically when watching a night scene. Any ideas?
A appreciate that my TV is old (about 7 years), but I'd rather repair than spend more money.
