Update;
Used a toothbrush and brushed back and forth on the upper gear rack to clean out eventual obstacles.
I believe it did some good after all.
Will do some more testing and eventually grease a few parts before concluding.

ldservice wrote: 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. Sorry to hijack this thread, but I have a DVL-V888 that works fine playing LDs on side A, but as soon as it flips onto side B, it starts to skip backwards over and over at about 1 or 2 minutes in, depending on the disc. I opened the player and checked the top track and I didn't see any dirt or bent teeth or other issues, and I also re greased the guide rod, but it still skips. I also tried that screw near the worm gear that rixrex mentioned, but I still have the skipping problem. I see you've mentioned here that there is a lever that needs to be reshaped, could you tell me about this lever? I am thinking since everything else I did so far has had no effect on this issue, this might be my problem. |

First thing to do is make sure the top guide pin is lubricated well. After that if it fails then the spindle motor centering could be bad. There is a small screw to loosen, then an adjuster you can turn, center between the extremes it would stop playing and tighten. The DVL series usually does not have the broken M Holder issue. |

Update: My DVL-V888 was having issues where side B skipped/looped within the first few minutes. I re-greased the guide rod, but when I hit side B and watched it play, I noticed the toothed track that the laser moves along seemed to be hanging a little loose, and the laser made a small clicking noise when it moved along the track to the start of side b. I propped small pieces of cardboard underneath the opposite sides of the track, so that it now sits flat without wobbling, recleaned the teeth, and now the laser moves along the track smoothly, and the player plays side b without skipping or looping. I guess the track was hanging a little lopsided and it was causing the player to skip? Anyways, now that I have it fixed, I have another issue. Side A plays fine with little issue, but side b seems to be suffering from a lot of video noise, which looks like crosstalk to me. Does this mean my laser is out of alignment? My audio is coming in fine, and it plays AC-3 without an issue, it just seems like the video is really noisy. |

I wonder if when you shimmed the track it changed the angle of the optics versus the disc surface? This would certainly create crosstalk... |

But if moving the track stopped the skipping, then it must have been something to do with the track, right? I have read you guys post that the other DVL players can easily have broken M holders, could that cause the issue? |

I'm waiting to see how long before the second gear post breaks loose on the M-Holder and it starts skipping on both sides. The loose rail is common to all players. You did a temporary fix, you need a new M-Holder. |

You did a temporary fix, you need a new M-Holder. Ok. I am in Canada, would you be able to sell me a M holder for my DVL-V888? And also maybe point me in the right direction of a guide or video showing me how to switch it out myself? |

You can write me at kbahr@comcast.net. I cannot remember the correct part number off the top of my head and would need to look when I get home but I can give your the part number and Pioneer Parts link. If you cannot get it I can help. |

My 909 is doing exactly the same now! At 1.04 minutes into side B it either jumps forward, or goes into a loop. It's been building up from very rarely to almost every time. When taken apart and running, you can easily see on the moving part, that something is wrong - yes you can even hear it. The lubrication seems ok, but the is a dryer spot just after the spot where it starts acting up. I've tried to adjust the screws as before mentioned - you know, first the black, then the white - but it did'nt help. So I put it back where it was. So now I'll try the other tip and clean the rail carefully before re-lubricating it. Any specific advice on how to clean it is therefore welcomed, as I'm not a technician at all  Can I use a clean piece of cloth, or do I need anything specific? I take it, that I after the cleaning grease the top and the side of the rail the way it was? Cheers! |

Use a brush or something similar that doesn't leave anything behind, then you should be good to go! For the cleaning and lubrication I would go the way ldservice and krbahr mentioned. Gloves are useful to apply grease. I haven't taken the step of lubricating my machine, so I cannot guide you any further. Feel free to come back to this thread with hints and how-to. |

i have a 1998 VIDEO MAGAZINE review that fingers the 909 as a singularly dreadful LDP, one of PIO's worst of all time, even. any opinions on that? |

Can't really say for sure. I have only watched a couple of LD's and DVD's after I fixed the repeating problem. |

Seems the 909 has a rather bad reputation. I've read several places that players like the CLD-2950 and the CLD-D925 are better LD-players. But in my set-up, the DVL-909 is the best so far (and I tried 'em all  ).

But in my set-up, the DVL-909 is the best so far (and I tried 'em all ).I share almost the same thoughts. My CLD-D925 vs DVL-909 has significant differences. The HQ circuit button makes the picture worse than with it set to off. I'm using nearly the same composite video cable on every player I have, but it should not make that big difference. In the end, my CLD-D925 may not be properly aligned and does not show its truly perfection. |

Well.... I have cleaned it as best I could, and applied new grease. But it stills skips, og goes into loop during the first minute of playing on the B-side. When adjusting the spindle motor centering I can move the point, where things go wrong. If I turn right, the problem occurs within the first 20 seconds, and turning left will do the opposite, and move the problem to between 40-70 seconds. Does this tell anyone anything. I am not at all skilled in the fine art of Laserdisc-reparing, mind you

I am not at all skilled in the fine art of Laserdisc-reparing, mind you I thought my problem was gone, but it came back when watching Blade Runner. It has been a while since it last showed up, but nothing major issue this time - happened only once. I have read one should degrease the rail to get rid of the old grease, then apply new grease. |

Well... The problem with my player began with it skipping rarely, then more and more often. Now it does it every time. The cleaning did'nt help a all. Funny thing was, that about a year ago, it started doing it a lot. And not really knowing anything about the problem, I cleaned the laser. It actually helped. for a while. Probably just coincidence though! |

Sometimes you need to replace the rail because it could be slightly bent, small amount you cannot see with the eye. |
