I am having problems with the horizontal bars on my set when in widescreen mode. Basically their not straight, the top bar bends slightly in the middle and the far right is 2mm lower than the far left. What makes it worse is the bottom far left is slightly higher than the bottom far right which means 2.35:1 transfers look like their slopping inwards at the far right. I know theres ways to get into the service menu but Im not sure if I want to touch that and Im not sure if it will even work. Any ideas ?.
