SOLD - Battlestar Galactica Blu-Ray Discs, The Complete Series. I bought this to watch while recovering from total knee replacement so it has been watched once. Still in AS-New condition. This is the official US release.
Without picture I doubt anyone could help. You really need to just watch the unit and see what is happening. These M-series and the other CD changers are problematic. They either work or not worth repairing.
You have to feel under the front left of the tray and find the wheel and manually turn it. One direction loads the LD and the other opens the tray. There is a 50/50 chance Pioneer still has stock of boards. It is normally cheaper to buy another player than buy parts. If you can solder wires to bridge the break that would be the cheaper way to go.
First, you need to make sure you have selected component for the output format from the main menu with no disc installed to get component color for DVD's. The selection I believe is either S-Video or Component.
