First steps of laser replacement on 2910/3910/5910.
I'm not done labeling these yet so consider this "PART 1."
... Part 2 will follow where it gets into actually getting the laser off of the rails and putitng it back on.
Getting the tray bezel off and prepping for faceplate removal
Removing the faceplate part 1
Removing the faceplate part 2
Removing the disc tray to access the laser
Prepping and disconnecting the drive to prepare to remove the Traverse Mechanism
... Part 2 will follow, as I have to label stuff a bit more meticulously and I have been just completely swamped (as some people writing do know)... Hopefully this will give folks at least an idea of what this takes. It's tedious but not impossible for a layperson to do.
More to follow, as soon as I have time to mark up the images. I really am sorry for how long this has taken as I just have had a lot going on, and this ends up falling to back-burner a lot.
IF YOU DO wish to go further than this on your own right now, basically you have to
1) Remove the drive, with four screws that are in deep holes in the plastic black carrier,
2) Remove the ribbon cable to the 'motor board' from the bottom of the drive -- carefully,
3) Lift out the ribbon cable going to the laser mechanism - extra carefully,
4) remove the screws in the rubber 'shock absorbers' on all 4 points of the traverse mechanism BEING CAREFUL NOT TO LOSE THE SPRINGS/RUBBER INSERTS. These tend to go flying. So be careful there, too;
6) Remove the two screw at the far end of the rails, the 'plate' that holds the rails in, and slide the laser mechanism off,7) **DESOLDER THE STATIC PROTECTION BLOB(s) FROM YOUR NEW LASER** ... This is where I really have to show pictures, but if you're adventurous you can find it yourself, some of the mechanisms have two 'blobs' (one for the IR/CD laser, the other for the RED/DVD laser), some have one (which shorts both lasers to ground); I use a "solder sucker" for this, the laser WILL NOT WORK unless these protection blobs are resoldered!!!
8) Slide the new laser mechanism on,
9) Replace the rail retainer plate,
10) Screw the traverse mechansim back onto the drive, making sure to replace and not lose the rubber bushings/springs,
11) Reattach the ribbon cables from the motor board and laser board,
12) Reattach the ribbon cables going to the drive from the motherboard BEFORE SECURING THE DRIVE (trust me, it's easier this way)
13) Resecure the drive with its four screws,
... then follow the disassembly steps in reverse
I've done about 8 of these now; occasionally the new laser is dead, but that's mostly been with the ultra-cheap "plastic" new ones; I try to stay with the HOP-1200S if available as it seems to be more reliable than the HOP-11xx ones.
Feel free to email me with any questions, though.
