V1 to 4 are pretty much the same lasers ( Junk ), I know but sum of us poor folks gotta put up with em’.

It is worth trying a few things, you did the lens cleaning thing, That’s always a first. You can also try and blast some dust out with a can of air, remove the black cover around the lens first.

Easiest way to adjust, take off the drive cover and pop out the white hub thing, to use it later. the tray has 2 screws holding it on the left side, remove them and slide the tray out. Now remove the screw holding down the right sled rod and you should be able to lift the laser out and flip it back without disconnecting anything, careful of the film ribbon.

If you have a tester, test the CD POT, write down the value of the top 2 contact pads on each. The 2 adjustments on the back of the laser, the left (facing with ribbon on top) is for the CD probably around 1200 ohms, turn it clockwise til’ about 800-900 Ohms. The right one is for DVD, should be turned to about 750 ohms. No tester, just turn a little bit clockwise 1/16 turn or less at a time and test (no more than 1/8 total – remember where it was! Best to have tester!

Flip the laser back down in place with the rod snapped back in ( no need to screw it down till you’re done adjusting) and test with a CD in place, drop the white hub on top of the CD to hold it and see if it works any better.

One last thing to try after cleaning is the parallax adjustment. It’s the white gear on the top. Fasten your laser sled back down, mark the gear where it meats the metal on the left side. Try adjusting 1/8 turns ( probably counter clockwise ). Some say this does wonders, I found it does next to nothing for a good half turn. For a good Idea where it goes try adjusting while playing music or movie, all the way one direction until skipping starts and back the other way until skipping starts, leave it around the center of those two points. Also, make sure the gear is tight and clicking good, I think this adjustment affects the outer tracks/files more than the inside tracks of a CD.

Replace laser unit only after trying all of that. You might go and buy a new laser only to find out it was the parallax gear that was off!
