Hi Everyone, I have a Pioneer DVD Player/Receiver which produces an error mesage at the top left hand side of the TV screen. The DVD player works fine but I cannot get rid of this error code. The model # is XV-HTD510. I tried resetting the unit and unplugging the AV cables and plugging them back in, as well as trying different settings on the menu, but I cannot get rid of this message. I would appreciate any thoughts! I called Pioneer and they were basically useless!!! The error code is ER (AV) followed by a series of numbers and the letters 'OK'.
