Hello. I got a D-34 that cannot regconize the cd, i got services manual and put the device in to Services mode and used skipp button to check and confirm that lazer cannot move. I already check the mechanism of optical part and everything works fine, so problem is in the mainboard. I checked caps around IC504 and IC 502 and everything is fine, i checked the connection from S+/- to pin 7-9 of IC 504 to make sure it connected. I dont know how to move on from now. Can anyone deal with this situation please help me?
Pls apply 3V to laser slide motor to test whether laser moves back and forth smoothly? If yes, means mobo issues. Check power supply for MPU1715 motor driver pin 4/30 and pin 36 of CXA1272 according to service manual. If repair service is needed, pls contact kaosuncd@gmail.com, thanks!
