This player was likely kept outside for an extended period of time at some point, so I completely disassembled everything to properly clean it. Anything corroded that I had replacements for was replaced, but I definitely did not have this panel so I had to give it a good cleaning. Below is before:

The boards were in good shape aside from the connectors between boards (MAIN to DYMC and FLKY to PWSB) and the connectors on the back. I took care to clean them well. The shielding on the SCART assembly had a good amount of rust on it, so I de-soldered it to properly clean it. Below is after cleaning.

Disassembling the front, there was a good amount of grass clippings inside, but cosmetic condition is actually quite nice given the circumstances.

The humidity caused the Side B button to be finicky, so I replaced it. Without a spare, I probably would have tried contact cleaner on it. Here is what it looks like dissected if anyone is curious:

Finally, I swapped in a VWR1269-A so I would not need to step up voltage.

The original CLD-D925 is mechanically switched, so with the VWR1269-A, the unit powers itself on when it is plugged in. It can then be powered off/on via remote. I'm fairly confident this player could be modded to change this behavior. Behind the power on button, there is an empty spot for a power button. I did not investigate to see what else what need to be done since I keep everything behind a switch.

I extend my sincere thanks to petimaci for helping me add this to my collection!

That's odd for Pioneer. My Sony, DVP-NS900 has a similar design and I always found it odd as the only way to turn it on from standby without the remote is to hit play or eject. Kind of a nuisance to me.

Indeed! I had looked at CLD-D925 schematics, but didn't notice the switch. It is the first component in the power supply. Likewise on the European DVL-909.

I contemplated just adding in the switch to the 120V one, but it would not fit in the same location. If I get brave or bored in the future, I might try changing the standby behavior.

What is interesting is the CLD-2950 does not have a mechanical switch, so I'm wondering why the change. Could this be due to some sort of new regulation introduced?

I think you could well be close with your assumption regarding new regs cplusplus as the European CE standard (if my memory serves correctly) came in around the mid 90s over here, so approximately somewhere between the end of 2950 production and the launch of the 925. My own 925 definitely has the CE mark on the rear panel but I don’t think my 2950 does but I’ll check later when I get in to my HC room. Btw I take my hat off to you guys with your restoration work on these players, very impressed indeed :thumbup:

Interesting. I do not have CE on the back of my CLD-2950, but I saw an image of one with a CE sticker near the power cord. User manuals for both mention which standards they conform to, but I did not see anything specific to standby.

I did, however, find this: https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:31998Y0116(01)

I’ve just been in to check mine and can confirm definitely no CE logo, but thinking back to my long since departed original 2950 purchased new in 1995 or 96 it did carry the mark, but obviously it was right at the end of the 2950 production run whereas my current player was manufactured in 1994. Unfortunately I couldn’t get the above link to work.

I had no idea it had that long of a run!

I fixed the link above.

Yeah if I’m recalling correctly here I think Pioneer retained the 2950 as the European flagship model for a little longer alongside the newer generation (but lower spec) models such as 315 & 515 until they eventually launched the 925 to finally replace it, I believe the 925 is actually based on the 515? Of course I do stand to be corrected on this though!

Indeed. Vast majority of CLD's '95 and later share same base. It doesn't look like the CLD-D515 is mechanically switched, so you could probably swap it into a CLD-R7G to make it 220-240V.

I have 3 D925 units where I've swapped out the power supply board from a US player. I've never found a way to switch the player from 'auto on'. The DVL players have a resistor you can move to get the player to behave correctly.

It would involve some tinkering around the Mode Control IC to see if it is even possible, but since I did not have a spare, I did not want to risk it.
