Hello to all in the group, I recently have taken on repairing a Beogram CDX, after doing some research on the common faults. Upon inserting a CD and pressing play, the disc spins for a short time, stop, then tries again to spin, then the disc stops. A very faint electronic sound is heard, then the question mark '?' symbol appears.
My first thought was to repair the vias on the decoder board. So I re-soldered/drilled all the vias, as well as all the 22uf caps, and one 1uf cap replaced.
Same problem exists.
As a side note, the laser is seen moving up and down 3 times, but the laser does not track at all. So a few questions, based on these observations:
- Is the spindle motor faulty and need replacing?
- Service manual says if the laser bobs up and down aprox 3 times, check around 4IC6202. How? No scope here.
- There are some overheating marks on the power board (see photo) Would replacing caps on the power board help?
- Does any work need to be done to the servo board? Are there known faulty caps on this board also?
