Hello guys, I purchased this week this CD changer to add to my old Pioneer Hifi, well, just lasted 1 CD playing, tried to open the tray to change it and add a full set of three, but got stuck, no opening tray and no response from any button, power but was not responsive and finally unplugged it. Plugged again and no standby led and nothing works.
Opened the case and there is almost one zenner diode that gets quite hot, enough to evaporate quickly the alcohol.
If I remove from the power supply the CD system, the display blinks, also the temperature of the zenner decreases.
But no sure from where to start, if it's a main cd changer circuit problem or a power supply issue.
Here is the service manual, and one image of the power supply and audio board.
If some one could give a hand would appreciate
