Panasonic SA-HT75 "no disk"
Player would display "no disk". I replaced the spindle motor (which was
bad), but got the same "no disk" display. Figuring I had mis-adjusted the deck screws I kept adjusting, then got the "F61" display. I replaced the voltage reg. IC and this fixed this problem. Now,,,,the laser (visible light) has stopped working, along with the motor that drives the laser sled. The laser itself can be seen moving up and down when a disk is inserted. I have triple checked all connections. Is there a common component likely at fault here? Is it possible I somehow corrupted the start-up protocol software? I do not have the schematics. Thanks for any info and help. |
