My Hitachi 32UDX10S has PIP. When I use it, and hit the pip channel button, the channels for both pictures come up with the one controlling showing green on a gray background. Very difficult to read. Hitachi national could not tell me how to change this to something readable. Neither does the TV manual. I figure there's gotta be a parameter I can change somewhere in the service menu to fix this. However, Hitachi won't sell me a service manual nor will they tell me what parameter to change. Anyone have an idea what I need to do to be able to play around with the foreground/background colors used for channel display when you have the PIP engaged?
