I have a DMR-EH75V that has stopped reading discs. It is not making the usual noises ("FOUR "chugs" followed by lower-pitched chugs"), but just quietly searches. I have replaced the laser assy. once (approximately a year ago with near zero post-replacement use), and it recently has started this problem. I am hesitant to try another laser on a trial and error basis since I am wondering if it could be a pcb controller (?), ribbon cable/connector connection or in fact the laser.
Here is what I have tried:
Service mode routine 4,1, Laser used time: about 1600 (was not reset when laser assy. was replaced)
Service mode routine 4,2, Last RAM drive error: No error (I think F00)
Service mode routine 4,4, Laser power: Nothing reported (because it can't find a disc?)
No error messages on the front display, (U** etc...)
I have cleaned the spindle and laser
released and reseated ribbon cable at the laser
Any insight would be appreciated.

Following through with this, I had AVS member mickinct do a repair on this, and it was great service! It was the laser (again) and power supply capacitor(s) was replaced as preventative maintenance. Thanks again!
