I have a 24PW6006 which I bought from Tesco and it's been back to Endeva twice with the same problem. The TV started to switch itself off after a few seconds. The first time they said it was a dry joint, and the second time they fitted a new painter chip. Although, it's working, they've done something to the picture. Basically it looks like the contrast is cocked up. I have the setting at 50%, but I can never get a proper black - blacks look like washed out greys. It's not that noticeable in daylight when watching news or soaps, but at night when watching movies containing any sort of night-type scenes, it's very noticeable. Also, I can see green lines which are in a zig-zag pattern on the screen. I tried to take a photo, but I couldn't get it to show what I mean, so I did a mock-up which is attached. The black bars are black on the TV, but the black areas of the scene are not black on the TV - they look washed-out as shown in the attachment. Also, the green lines are not quite as prominent as in the attachment, but are very noticeable on the darker areas of the scene. I really don't want Endeva to come out again, as it's difficult to show the problem in daylight, so I was wondering if there was a way to adjust it using the service menu etc. Thanks in advance for any advice.
