I have a Pioneer CLD D515 with a defective power supply. In order to repair it I would need to get to it, however the tray is in its way. Turning the little wheel with the belt only opens the smaller CD tray, but not the large LD tray.
The LD tray stays firmly locked in place, I cannot move it more than a few millimeters.

What can I do?

Not sure if you can find any clues with this, it's the same CLD-515 model. I think, not sure if its the bigger wheel that needs to be manually turned or if their is latch maybe locking the large draw in place?

Look at the pictures in the previous post. Go to the picture with the arrow to the loading belt. On the top you see part the a white piece that can side sideways. You need to turn the unit until the mechanics are in play position. Then press in toward the middle on the flat part of the white tab you can see from the side. This is the tray selector. You should feel it move inward as the mechanics come down and the the entire tray will come out.

If the power supply is completely dead you only need to cut out the arc suppressor (looks like a diode) back by the power input and then replace the fuse.

Thank you very much for the tip.

I couldn't find any spark gap, neither on the board nor in the schematics. However I have found a short diode D23. Chances are this might have been caused by C22 developing a short. Given the age of the power supply I'll be swapping all electrolythic capacitors.
No fuse has blown BTW.

Replacing all secondary capacitors in the power supply didn't help.

There should be a 1 or 2.2 mfd/50V cap on the primary side of the switching transformer. If it fails the power supply won't "start" and the fuse won't blow.....

Thanks, I've found a 1µF/400V one. I have replaced it with a 1µF/100V one and now it starts. I'll try to replace it with a propper one tomorrow.

Thanks

Very cool

This brings back many memories of fixing Sony SLV-R5UC S-VHS power supplies. Cannot count how many had this failure.

Hello to everyone

Yesterday I got a nonworking Pioneer S315 that used to work utill a month ago (the seller was selling it a lot higher then). I got it for just 35 euros and 6 movies in great condition were included.
The player seems completely dead, no power, nothing. Since this player has the exact PSU board as the 515 model, I thought I'd post here.

Already checked the fuse, it is NOT blown (and also this board doesn't seem to have an ARC supressor) so I've already begun replacing caps. I hope my problem is the same cap as casandro's (1uF 400V) but I don't have one of these so until I buy one today I don't know...

My main question is...
I plan to replace ALL electrolytic caps on this board BUT I want to know one thing... are there some of them that need to be low ESR or any regular cap of the right value and voltage tolerance will do? I'm arleady half way there but two 2200uF 16V on the secondary part look like they're low ESR.

Please casandro, if you read this post and you still remember, shed some light for me.

It was the same cap for me too afterall, C12 1uF 400V. It works now...

You guys earned your JTC (Junior Technician Certificate)

Well I had some experience already with fixing retro computers (ZX Spectrum mostly).
From a search of the model numbers on the internet turned out the original caps on the psu board were not low ESR so I replaced them with regular 105C ones.... specialy the 1uF 400V I think needs to be 105C because it is really close to the switching transistor's heatsink and thats probably the reason it goes bad first...
