Hi all, I'm looking for some help here. I've had this older magnavox cdb650 (same as philips cd650) cd player for a couple years now. The cd player did not work when I got it, and was shelved for a couple weeks. Then one day I powered it up to tinker with it, and all of the sudden it was working. I listened to it for a couple weeks until it spopped working again. Last night I got it back out and popped the hood, fiddled with the tray and transport and it started to work and is working now. I don't now what I did to make it work or if it just coincidentally started working on it's own. I've read good things about this cd player and it's mod potential which is the reason I'd like to hang on to it and get it working. I was looking at the large board under there and noticed some solder blobs that look like someone was up to something. The PO was an electrical engineer and audiophile , so it wouldn't surprise me if he repaired or modded this unit. I'm attaching some pics hoping someone can tell me what they think. As far as symptoms, when the player works, it works 100%. When it doesn't work, the motor and spindle just spins away as long as the unit is powered up. If you load a cd, it will go in and spin, but the player will not recognize it and shows some sort of error on the display. If you eject the cd it comes out spinning full speed in the tray. If anyone can guide me through some troubleshooting, I'd really appreciate it. I know my way somewhat around vintage tube gear, but cd players are absolutely foreign to me. Thanks.
