So I found my old Pioneer PD-206. I put in a CD and with a little help closing the tray (as the belt is stretched, ...nothing happened
I entered service mode and checked that the laser was firing, and the motor was spinning.
Then, I sprayed some contact cleaner on all trim pots and moved them end to end, and re-set them to their original position. After this it started doing "something".
I got the manual and started the calibration procedure. I fudged with the RF level pot and the focus gain until I was able to track focus (i think): the CD started spinning clockwise and i could hear the focusing. Scoping the test point showed me some waveforms close to what the manual says.
But when I turn the unit off and on, it tries reading the disc and "crashes": it won't turn off, or respond to anything.
I don't remember if this player was already not working when I put it away (in the early 2000s I was using a Sony player after this Pioneer). So i'm not sure if it could be a bad pick up unit (new ones are out of the question - $150 each, and a new player costs less).
Any ideas?
Edit: now that I think about it, this wasn't MY old cd player. I must have got this one for free at some point. My old CD player was a pioneer too, but it was a dual deck. So maybe this one is just dead. Again i'm not sure if it could be a bad pick-up or something else. Do these pick ups fail as often as late 90s pick ups? I remember, at my dad's shop we changed hundreds of KSS-213s. these failed a lot.
