Post subject:  Looking For Service Manual + Capture Question
Looking for the service manual for the CLD-2080. I of course checked the pdfs in the sticky first and it just had schematics.

Also I was wondering if it is possible when capturing to bypass the comb filter of the CLD-D504. The schematic shows a comb filter is applied to all the outputs or have I misunderstood it?

Of note, the 2080 is producing by far the best capture results of my players. It really is a trooper, but I am thinking a couple of the others could stand to have things calibrated and whatnot.

For CLD-2080 you should be able to use CLD-3080 SM. I have the ProScan clone SM of the CLD-2080 though.

Yes CLD-D504 has what is called "recombined composite". You can bypass comb filter in CLD-D504. It is CXD2023Q. Datasheet for this IC (not SM) shows same info on Pin 71 as the post here: https://forum.lddb.com/viewtopic.php?p=98007#p98007 so you could then make a custom S-Video Y -> Composite cable or tap R145.

Regardless of picture, CLD-2080 is much better built than CLD-D504. Video quality of CLD-3080 though is a jump up from CLD-2080.

Thanks.

My other players are an LD-S1 and Proscan PSLD46. I can definitely tell the 2080 is much better built, it is a brick house. Funny enough it was my first player and bought for just $10.

I'd love to have a LD-S1. I would think that would be the best option, but there are a ton of electronics jammed in that unit so who knows how they are holding up 35 or so years later.

PSLD46 can probably have same composite mod done on it. You can also mod it to use Pioneer remote if you don't have RCA/ProScan remote for it.

I have not done this mod yet, but I do have several players with the CXD2023/CXD2024 chip that I need to refurbish.
