Hi!
This topic is related to my previous topic about the abnormal behaviour of my DVL-909.
The problem still persists, so therefor I will take apart the player for a proper inspection, cleaning and new grease.

There is some grinding noise when the laser optics is changing sides. I will for my own purpose take pics during removal of parts and for reference when it comes to reverse the removal.
I will not consider myself as an incompetent when I'm working on electrical equipment. I have done things before with great results, but I have not yet taken apart a Laserdisc player.

I will take my time and not rush through this. I assume most of the Pioneers dual sided players are of the same kind and the procedure is almost the same.

What should I look after, and what parts and screws should be left in place?
Is there any alignments required after doing this job?

If someone that have done this kind of job would share some knowledge, I would be very happy.

There is just a little binding as the pickup is transferring from the guide rail to the pin on the turn mechanism. You just need to apply white grease on the rail.

i performed a full disassembly/refit of my 1988 PIO CLD-3030 late last year, when i had to replace it's transport/laser block.

i cleaned, then re-greased all gearwork and moving mechanical contact surfaces with LUCAS WHITE LITHIUM readily available
from HOME DEPOT. the deck sings like the proverbial canary now, surely at least as good as when brand new.

kind of wished i'd have thought to have documented the refit with photos and posted it all around here for others to possibly benefit from, oh well...

Thanks for inputs!

Disassembly went easier than first thought...
The hardest part was to remove the ribbon cables all the way around the side changer, but I got them removed after a little bit of pondering.
All of the gears, and the gears attached to both of the motor holders were in great shape.
The gears rack seemed to be dry with very little to no grease at all. Some places there were burn marks on the gears rack, probably after friction.
The guiding rods had a thin layer of grease.
In the time of writing, the white grease I have ordered is on its way. Hopefully it will be here by the weekend or next week.

High hopes of making it fully functional again, but no guarantee as we speak! Patience is the word in the meantime. :thumbup:

Player is up and running again. Cleaned all the gears and applied a little bit of grease in places where I knew there was moving parts involved. I didn't put too much on it as that would make a mess.
Flipping side from A to B is much more silent than before and do not grind anymore. The skip back problem is cured! :thumbup:

No, the bad thing.
During reassembly I put the ribbon cable for the CLD assembly the wrong way, so the ribbon cable would make "waves" during movement of the optical pick up. Sadly, my mistake caused a little, but visible, scratch on the side of the ribbon cable.
Now, I believe this scratch has caused the wire in the cable to loose its connection point when the optical pick up is moving. Didn't have this following problem before, but some times the player is having problem locking onto chapters on both sides.
Can't be sure that this is caused by the scratch, but the cable is controlling signals back and fourth to the optical pick up, so it could make sense.
I have not been adjusting anything on the optical pick up, just removed the cable and greased the "tunnel" for the guide rods.

I have found the service manual for the DVL-919 and the part numbers for the cables are;

VNP1582
VNP1583

I have no spare parts for this machine right now, and I would like to get hold of these two cables as they are delicate and easy to make irrepairable.
It was not my intention to scratch it or trying to break it.
Sadly, the parts I have found are not available for shipping overseas from Pioneer.
There is no repair shops nearby that would have these cables.

If I could find a DVL-919, would the parts be identical to the DVL-909, no matter the year of manufacture?
If someone are having these cables and happy to make a deal, PM me! :)

I think I have that flat ribbon cable available. It is the one going from the actual lens ... ?
Post a pic if you can....
Don't have the Sm for the 909-919 around....
But I do have all parts laying around!
Shipping would be reasonable I'm sure. No weight on that specific item :thumbup:

btw.: VNP 1582 is the actual lens IMHO (you don't need that I imagine?)

Thanks for response, Kris!
No, I don't need the actual lenses, only cables.
The cables are detachable. The orange ribbon cable for the DVD has a smaller cable connection and it's secured by a locking tab. Unfortunately, I do not have a picture of this one.
The orange ribbon cable for the CLD has a wider contact point and it is pushed in placed, covered with a white plastic to prevent damage. This one I have a picture of.
Overall, they are of the same width.
I tried to upload some pics, but the site gave me an error.

I have a barcode sticker on the lenses if that is of importance.

CLD - 3300273881
DVD - 3900045436

Crystal clear now...
I'm sure I have these around
I'll look into this this evening and send you the pics of the cables.

That sounds great.
I'm sorry I couldn't upload my own pics.

Bigmix007: I used this kind of Dow Corning Molykote lubricant, if I'm not mistaken. It's been a year since I bought it and cannot find the listing in my eBay purchases. It should be safe and compatible with metal and plastic parts at the same time.
Worth the purchase, the player went smoother in operation. But after reassembly, I accidentally made a crack in the ribbon and I believe that's what causing the problems I now have.
