I just acquired a KV-4000 that needs attention in the following 2 areas. Any assistance that you can provide is very much appreciated - thanks in advance.

I am getting dark horizontal banding wherever there is a light area on the screen - for example, if there is a line of 1/2" white text on a light blue background in the center of the screen, then the whole 1/2" horizontal area will be a darker blue band there - the text is not smearing, and it is razor sharp. When watching a DVD through the video input, there will be numerous occurrences on the screen as the scene changes. I am not using the built in tuner, I am only using the monitor inputs. Not sure what this is, but adjusting brightness and contrast do not affect it.


There are markings for horizontal centering and vertical centering on the board, but I do not see any adjustments on either side of the board - no VR pots, no switches, no plug in pin - the horizontal centering is way off to the left. How would I adjust this?
