Pioneer PD-T503 CD Player - Power?
Hello,
I was wondering if I might get some advice. I'm not a repair technician, but thought it would be nice if I could fix a CD player I've acquired in a broken state. I've read through the FAQ and the newsgroup. I have some electronics knowledge, but not much. The unit is a PD-T503 twin tray CD player (Pioneer). When plugged in, the display lights up and stays on with all the track lights on for both trays and the disk 1 & II indicator lights, but none of the other lights for other features are lit. The sled motor seems to be getting power because the tray moves out and in about 1 inch when power is on (possibly another problem?). Pressing the power switch does nothing (ie. the display stays lit and nothing else happens). None of the buttons do anything when depressed when the power is on. Any ideas here? The unit has the typical test pins so I could try jumping those and testing that way but is it going to help or is there an obvious fix here? Any help for a newbie would be greatly appreciated. Thanks! |

Pioneer PD-T503 CD Player - Power?
These are real prone to mechanical timing problems, and chewed gears.
Most DIY types, and even many techs, would be out of their element on these, at least without a service manual, including the separate manual for the mechanical adjustments. Mark Z.
