52200 is the last frame before lead-out, but if you go into test mode and turn off the tracking servo you could see what is after this. The same holds true for the start of the disc. |

This is probably the first time we have knowingly watched RLV video, so many thanks for sharing this with us.
The video quality is much better than I expected. Where there any picture stop codes? I was thinking that they could have just put this on tape if they did not need to take advantage of the random access or still frames. |

Judging by the disc saying "videowall" on the label, this makes more sense to me as to why they chose LD. I am assuming videowall is referring to some sort of composite public display. You would definitely need random access if they were displaying this at a convention, etc. Disney used laserdiscs in the lines of some of their rides because of the looping capabilities. |

There was someone who posted here about a year ago who had one or two Disney LDs for sale that I think were used for rides. I think they were in the custom 3M jackets and sold for $100 or so.
I don't know why they had 3M make the discs when Disney themselves had a LVDR 610A. |

If it was not for you pokefraker I seriously doubt any of us on here with perhaps one or two exceptions would have ever seen these discs in action, if there are exceptions they have not come on here with the detail & actual footage you have so kindly provided.
You have put quite a bit of time & effort into your input & please be sure it is genuinely appreciated - I am pretty sure not just be me.
Indeed. This is fantastic. Thank you. |

Congrats!
It sounds like there is something wrong with pin 4 (color) of the S-Video connector, but I wouldn't worry about S-Video at all. |

Welcome to the forum and thanks for the detailed post.
It looks like the LV-510 might be a CLD-D503 with optical added. For the remote, I'm assuming the model is RC510LV. The only test disc available is GGV1069 which will work for you. https://www.pacparts.com/part.cfm?part_no=GGV1069&mfg=Pioneer
It does sound like someone went in and started making "adjustments".
Centering can cause track skipping as well, but it can't be too far off if the CD plays. The centering adjustment point might have a locking compound on it, so you can see if it has been tampered with. Tracking needs to be checked as well.
If you email the manual to manual@lddb.com, that would be helpful. |

I found two more articles that help to shed some more light on sales:
From Billboard's August 1st, 1992 issue: 200,000 units of Fantasia and 100,000 units of Ghost were sold. At that time, it cost $7 to manufacture a laserdisc (in large volumes), including the packaging.
From Billboard's February 11th, 1995 issue: 350,000 units of T2 and 290,000 units of Top Gun were sold. 7 million units were sold in 1993 totaling $267.5 million. 8.3 million units were sold in 1994 totaling $345.4 million. |

If they are single-sided discs, with red on one side and silver on the other, then they are RLV check discs. RLVs can have mint marks like replicated discs.
Check discs were made before the cleanroom glass mastering stage in an effort to prevent costly errors with audio, video or LaserVision flag encoding. |

That is a pretty unique player: single-side with AC-3 RF out. Not all of them have an AC3 output Interesting. Service manual shows it as well. It adds to the weirdness of "I can afford a 5.1 system, but not Both Side Play". Especially when the CLD-D504 was only $125 more than the CLD-S304 :think:
Anyway spyrogyro, that is a nice haul. I'm quite fond of demo discs. |

It wasn't cheap at all to go through all this. However it still worked out FAR cheaper than trying to source another 925 in unknown condition. Honestly, you are quite lucky to have found someone willing and able to repair and service it for you.
It was a film I wanted to see and have no idea if it exists in better quality. Can't find another LD of it either. 3 Men and a Cradle (1985) [VL5192] See above if anyone knows? Drei Männer und ein Baby (Trois hommes et un couffin) (1985) [081 808-1] 3 hommes et un couffin (3 Men and a Cradle) (1985) [SF050-1434]
Might need to brush up on either your French, German or Japanese :D |

Disclord posted some very insightful info here: https://forum.lddb.com/viewtopic.php?f=32&t=2121
2P (photo-polymerization) is sometimes called cold-casting or cold-pressing because it does not use the high temperature involved in the injection molding manufacturing process (hot PMMA is injected at a high pressure into a mold).
With the 2P manufacturing process, photopolymer plastic is stamped (transferring the pits) and then cured with UV light. |

The black and white photo pokefraker uploaded here is from the last page of Videodisc and Optical Memory Systems. Isailovic. 1985 and the color one is a still from the video he posted under it.
---
The ODC LVDR DRAW (Direct Read After Write) recorders entered the market with the LVDR 610 in 1984. The system initially consisted of three components:
611 Studio Console This is the base machine. It contains two lasers: the Ar gas laser that writes and the HeNe gas laser that reads. The disc was suspended in air by gas (possibly CO2) from a tank housed in the bottom of the unit. The purpose of this was to keep a constant distance between the objective lens and the disc. The electronics that control the servos, operation, power, etc were rack mounted. The price was $160,000.
612 Vertical Interval Encoder/Signal Generator Responsible for encoding LaserVision frame numbers, chapters, etc in the Vertical Blanking Interval (VBI).
613 Video Monitor package Optional add-on that included a Tektronix 650HR monitor, 1740 waveform monitor, and 620 X-Y monitor.
The total price of the complete package was $200,000 (this would be just under $500,000 today). In order to be eligible to purchase a LVDR system, you needed to be a licensee of DiscoVision Associates. Additionally, ODC offered the 615 Pulldown Processor that automated frame flagging and the 616 Evaluation Station to check the RLV after recording.
Eventually a revision of the LVDR 610 system debuted by early 1986 known as the LVDR 610A with improved audio and microprocessor control. The price remained $200,000. Of the two widely circulated photos, the black and white photo is the LVDR 610 and I believe the color one to be the LVDR 610A. The latter is from a Pioneer video describing the laserdisc manufacturing process. In the video, it appears the LVDR is being used to create a “check disc” before production reaches full-scale. Notice the ventilation installed which might be used to vent the gas used to suspend the disc while recording or the gas created while recording the disc. The PAL version of the 610A was known as the 620A. At some point it became possible to write both plastic and glass discs, but glass was not an option in 1985. Glass RLVs were more expensive, but provided better quality. The LVDR system supported both CAV and CLV, but I do not believe digital sound was possible.
At the height of RLV production, there were 40+ LVDR systems operating around the world, from Asia, to North America, to Europe. ODC was even awarded the Engineering Emmy Award for the LVDR in 1988. As LaserVision eventually declined, so did RLV and the last RLV Service Bureaus closed in the early 2000s not long after worldwide laserdisc production stopped. ODC would continue to operate after renaming itself ODC Nimbus.
Sometime around a decade ago, ODC Nimbus closed its office and remaining assets were auctioned off in 2015. I was able to view photos of the items auctioned and did not see anything related to the LVDR or RLVs. I reached out to one individual who visited the Laserdisc Recording Center (a “RLV Service Bureau”) around 2003 to purchase some laserdisc players from them. He obtained a blank RLV in the process. He asked to see the recording machine, but he was told it had been thrown away. It is safe to say almost all were scrapped.
RLV The key difference between laserdiscs and RLVs is the extra layer of a thermo-reactive dye mixture between the plastic and aluminum that gives the discs their characteristic color. Similar to the ablation of the photoresist coating on a glass master we see in laserdisc mastering videos, this dye was carefully selected to allow for the maximum absorption of the 488nm (blue) Ar gas recording laser while remaining transmissive to the HeNe (orange/red) reading laser (and later infrared semiconductor lasers). The discs are hollow inside and no amount of pressure should be applied to the surface of the disc. The price per RLV was $75-100 in early 1985. The second revision of RLV discs were known as the RLV Mark II. |

My LD-S2 would not eject at all when I bought it. The original grease had become quite sticky. I cleaned and replaced the old grease with fresh white lithium grease and have not had a problem since.
See the spots marked 2 in the attached image. I would just replace what you can easily get to in order to avoid any issues that might arise from further disassembly. |

Thank you! Mine does the same. I'm in no rush to open this beast up but maybe if I get the courage to do the AC3 mod I can do both at the same time. Yeah in addition to the LD-S2, I think every CLD-X01/CLD-X02/CLD-3070/CLD-91/CLD-92 I've seen has this dark orange sticky grease. Disassembling the LD-S2 to the point of where you can get to this grease is tedious, but straight forward. Service manual is available here. After resolving this problem, it seems like the LD-S2 tray comes out much faster than my other players.
I love how we all share knowledge and help each other just to keep these things alive! Absolutely. I've pretty much learned everything from the community here. :thumbup: |
