Hello, I have a Beogram CD3300 that does not play the CD’s.
It’s behavior is as follows for all CD’s. It spins for a while and does not read the TOC and displays the symbol ?
I have the service manual and test equipment available but it does not tell me how to get access to the component side of the PCB’s. I guess the problem is related to laser focus or power. Could anyone shed some light?.
I have replaced the gearwheel and belt on the glass plate drive and wonder what the correct sequence of events shall be.
When i push eject the plate is lifted about 15mm and then the drive starts slipping due to some light obstruction at the eject switch mechanism which is easily overcome by my finger assistance. The glass plate will raise to a near vertical position to allow me to insert the CD. Pressing “play” lowers the glass plate to close and bounces about 4mm up when touching the deck and settles in the normal closed position after which the CD starts to turn a very little bit in the wrong direction after a second it will turn correctly sometimes for a few seconds, sometimes for a lengthy period of time but no display of the TOC. When the disc spins I can step the tracknumbers as indicated on the display but no sound and finally it stops displaying the dreadly ?
I noted this model has a built-in test routine by applying a ground to pin 4 of the IC6078 on the control panel pcb and simultaneously applying mainpower to start the routine. Question shall pin 4 remain at ground during all tests?
