I have a few Sony cx-995v units one of them has started failing to read some disc that I put in the unit. Doesn't matter if they are new or backups. The unit only had 2800 hours according the the usage log found by entering the "Start Testing Mode" b pressing Top Menu, Clear, Power in sequence.



I searched this forum and found a discussion on replacement laser DBU-3. I ordered it from AliExpress.com The unit per it's label the same model as the one I removed...


I installed the laser in the player however the laser doesn't emit any light like the original nor does the disc spin. I removed the unit and reinstalled the old unit. It spun the disc and emitted light. I swapped back and forth a few times with same result..

Looking at the AliExpress.com website there is a vague instruction.

Since the laser diode of this parts assembly is treated to prevent itself from electrostatic breakdown,make sure to remove the solder.


Can anyone explain where to remove solder or share what they did to get their replacement laser unit working ????
