My guess would be either something in the track that the small movements are having trouble getting over where the scan has more torque or you need to re-grease the metal guide rod. See if there is any excess grease where the pickup goes onto the turn mechanism and spread that on the metal guide rod. Don't worry about the missing screw.

Thje screw isn't missing, there never was one insatlled there. Is the problem on side A or the first few minutes of side B?

Just a thought, could it be laser rot? I played Lethal Weapon on my 95 last week, and on side B, it started skipping and going back to the same part. Then, the player had trouble focusing and had stopped playback. I had to eject the disc and fast forward to get past the rot.

If this happened on both sides then the problem would point to issues gears on the pickup or I've seen bad pickup movement motors doing this. As long as no-one cleaned the guide rods to take the grease off them.

I have seen this on three DVL players already. Two of them simply needed the gear tracks brushed clean and relube of rail, etc, and they ran fine after that.

The other one had some sort of problem in the laser assembly gearing that cause some rough spots on that gearing that I had to deburr, and also had a defective metal "brace" that was pushing on the worm gear too hard. That's a metal U-shaped type of pressure spring that rests against the tip of the worm gear and is screwed into the assembly body with small screw. It is easily visible if you look at the assembly from above when it is on the lower track. I had to remove that, and the problem cleared up just fine. It worked without it, but I still got another one to replace it.

If it's doing this at the first 2 to 3 minutes of side B there's a lever that needs to be VERY carefully reshaped. It acts as a brake against the optics. That screw should be tight. It sets the centering for B side play....
Also, was the DVD that came out broken in any way? I had one that had a DVD stuck and the DVD was cracked. It dropped plastic bits onto the optical rail and blocked optica travle at various points. Cleaning the rail fixed the problem.

You mean the white screw I have pointed out in the picture or the black one? The white one is loose no matter how I try to fasten it.
Dvd is not cracked and the surface is covered with some amounts of white grease.

I want to clean this rail, but I'm know sure what kind of grease I should buy. Do you have some advice, Ldservice?

i would also use a small paint brush, you don't need much and the brush won't fall apart like a qtip would leave fibers.
