Troubleshooting CD Players

The guy sent a replacement the same day I complained so I don't want to blacklist him yet, maybe I just got unlucky with the first one. It's a CD parts store that I've used before so I'd like to give him the benefit of the doubt.

The output of the new pickup was the same level as the original. Is that a coincidence or is there a possibility of something defective in the deck causing the same low rf height in multiple pickups?

I can't say, too many variables. Does it play any better?

Not really. I'm going to put this one to rest, like you say too many variables, not really diagnosable by message board. The continued advice has been appreciated though, thank you, it's been applicable to other decks I'm looking at as well.
 
The replacement pickup arrived. After installing it, the problem discs played fine. Player now seems fixed.

If this pickup doesn't die after less than a week like the last one then I'll post the name of the seller so his name can be added to the good supplier list.
 
Sony CDP-55

It skips. Per the top post of this thread: The motor has been oiled and the rails cleaned multiple times, no improvement. Next I tried stretching the springs, after doing that the player not only skips but is now also sensitive to being tapped/touched during playback.

Re-read the instructions and check each thing one at a time. For example, do you hear any scraping noises? Something could be rubbing.
 
Hi, I also have a problem with a Yamaha CDX-510. I opened it to clean and relube the insides. The clamp that holds the CD in place has a spinning middle section, kept in place by a piece of plastic and two screws. I took it off and there was a small metal ball embedded into it, on which the center piece spins. It had a fair amount of thick, yellowish grease. I cleaned that off and added some new, thinner mechanical grease. Now it doesn't play at all. It struggles to read discs and can't hold them in place. They play normally if I hold down the center with my finger. It has also started to rattle. I think that grease was supposed to be that thick and it wasn't just dust accumulating. Could you tell me what kind of grease it was and how I can find something similar?

here's a weird one... Yamaha 5 disc carosel would only sense 2 of the 5 discs. So I took it off the shelf and stashed it. It's been sitting for a few months, and when I tried it yesterday... tada! It works perfectly! What's up with that?

Obviously.. your 5disc changer needed a break, after all, you were working 5 of them for the price of 1 :dunno:

That's not fair :no:

:rflmao:

Just having some fun.. No, actually the platter was probably jammed or off gearing and when you placed it on the shelf, may have jarred it back into position. I had a similar issue with a Panasonic 5 disc, I opened up yesterday. It's just the gearing mechanism be realigned and then synced with the command button for "opening". These platters are very sensitive to shock, and just the right mis-intentioned jolt can make them misbehave :thumbsdown:

A couple pictures (in focus, please) would help. You used the correct grease. Light weight lithium.

Thanks! Here is the CD mechanism with everything attached:

This is after I took off the two screws and wiped the lube:

And this is the amount of lube I put there:

Unfortunately I don't have any pictures with the initial lube.

Check that the springs aren't sagging on the mechanism. Something is rubbing and you have to inspect it and find out what it is, but what you did so far would not cause it.
 
Hi there.

I have a cambridge azur 540c , I am into it by about 50 bucks.

Got it with draw will not open, door errors.

Pulled apart, belt stretched, so thought great. Got new belt, but is more like O ring vs other that was more square ish.

In between waiting for belt, I can get the player working fine by manually closing tray etc, ran for a few days, one day it did start skipping, removed power, started again, and all good. May have been something also to do with that disc as was scratched.

Fast forward, new belt, but draw will not open close still, motor spins and belt deflects as it is really trying, draw does seem somewhat stiff but has ample white grease it seems. So at this point, I am wondering if the motors get weak, or no, I may do full disassemble and clean out all grease etc and put a very light oil, I guess the tray should really be fairly easy to push closed ?

Looked around everywhere, seems they usually only have the belt issue, maybe it is a combo not perfect belt, slightly weak motor & draw mechanism stiff due to something unseen ? TIA
 
The player needs a square belt. A round one will not work. Measure the original belt (Google how to measure a tape recorder belt) an go to www.vintage-electronics.net and buy a belt 10% to 20% smaller. They are cheap, so buy a couple different circumferences and see which one works best.
 
I own a Sylvania CD 1560 CD Player. This player plays some CDs, but not all. For instance, it plays the very first CD that my father gave me with the CD player. This was the Beatles "Sargent Peppers" CD (only 34 minutes long). It was produced around 1987. I attempted to clean the top of the laser lens, but that didn't help. I then removed the screw toward the rear portion of the top of the laser assembly hoping the thin, spring steel laser lens holder would be released, but after I removed the screw I still couldn't raise the spring steel lens holder. Is it cemented in ? Does anyone have experience with cleaning this type of laser, or maybe you know why it doesn't read some of the disks? It's a really nice unit with no belts so I would like to get it working againCD Laser.JPG .

hi there,i have a sony cdp-xa50es cd player,
it has started to do something very weird and asking to see if you know what this might be,t
the player started to need warming up a while back, it will say on the screen that there is no disc present for about half hour till warm i guess,
now it is doing something new,it will play as normal but now will just stop and say no disc present, its a shame that this is happening as the player is a really cool piece of gear, any input would be great

I'm sure dr*audio will share his opinion, but from my experience, once a CD player starts reading "no disc present", a new laser is needed. Good luck.

This is an old Philips mechanism. The laser is bad and no longer available. You may be able to increase the laser power. If there is an adjustment it is detailed in the service manual.

I believe the laser is bad. I don't think you are going to be able to find a reliable source for that laser, I haven't seen one.
