The picture on my new JVC AV27D203 is too dark for my taste even after much fiddling with the standard controls for picture,brightness, etc. The "factory" settings (middle of the scale) out of the box were very dark. I can get a better (brighter) picture with the brightness setting 3/4 or higher on the scale, but there still seems to be a darker than normal cast to the picture- black areas are really black and little detail is seen. From what I understand, having the brightness way up isn't great for the tube either. I'd appreciate feedback on things I could do to try to improve the set's picture. I really like the set's picture sharpness and features so I'd like to try to do what I can with it before getting another set. I assume getting a calibration DVD like AVIA would be a first step? And how about getting into the service menu (Does anybody know the code to access it please?) & making further adjustments there? Would I need a JVC service manual? Thanks for your help!
