Technics SC-CH515 CD Tray Does Not Stay Open

I recently purchased this system (second hand). When at the owners house to take a look at it, the CD tray would not stay open. When you press the open/close button it opens fine, but it closes immediately without giving you a chance to put CDs onto the tray. The guy told me that this had happened to him a few years back and that he ran a CD cleaner disk through it and that it fixed the problem. So, for the price that I was getting it at, I decided to take a chance... I purchased a disk cleaner (no liquid, just brushes on the disk) and a can of compressed air (we figured it was a sensor problem since the mechanism seems to work fine as it opens without any hesitation) to try to fix it. After using the compressed air it worked fine - once. After that it went back to its' old tricks. Other that that, the system works / sounds fine. Any help would be appreciated.

I DO NOT think that problem related with CD cleaner
3 possibility here
1 The loading belt was lose it can not open fully to reach the switch open when the time limited was out as program design from system control it automatic close
2 The loading gear system out of position 1 tooth
3 Dry joints on switch open and close or connector from CD tray to system control intermittent contact
In any case it require a qualifier Tech from Panasonic to reset the timimg gear or service
I hope that give you some ideas if you need further info or service manual I am willing to help you out
Cheers

Cd tray closes quickly without pressing switch on Technics SL-pd688


There is a small switch under the tray that stops the motor at the end of it's travel, also one when the tray goes back in.
These can have wires broke off or can be stuck or open circuit

Discs not playing


Don't know this issue with this particular player, but have had other Technics (Matsushita, Panasonic...) CD players doing something similar to this. In most cases, those were carousel players instead of single disc players like yours. These units had optical sensors that determined the presence of CDs in each tray slot by determining whether light was blocked from its LED to its sensor when a disc was present... no light at sensor meant that there was a CD in the slot. The sensors interpreted a shadow as an indication of a disc in the tray. I've had these sensors fail and not be able to determine that a disc was blocking its light signal... the players didn't "see" discs so they wouldn't play them. Solutions varied, but cheapest, easiest solution was often to open the player and blind the sensor completely with a piece of black electrical tape. Most of these sensors I have encountered got too sensitive, so that any light at all inside the player was seen as an empty slot. Blinding the sensors "fixed" most of these players, but disabled the ability to really tell that any given tray slot was empty.
Or, since it is an old player, there is also the possibility that it has simply run its course and the laser assembly has failed.

Good Luck.

Inoperable cd tray on technics spl110 single disc cd player


Somehow the "gears" (side of tray has "teeth/gear" and wheel to the right of it has 'teeth/gear") which guided the cd tray were misaligned. With trepidation and fear of fully breaking it I lined up the tray and large wheeled gear to the right of tray.
At first I could get it to close to a certain point but it wouldn't go any further. I couldn't figure out what was stopping the closure but finally figured out the "teeth/gear needed further alignment.
During the repair found date CD player made was 1986 !!!! So I figured I'd just have to buy a new one. But it works like new and still sounds great
Go figure. Technics is a great brand.
What I saw as a white "wing nut looking" part had nothing to do repair. But during repair part of the front of repair dropped down and prevented closure. But there is a metal wire under tray which can be manipulated to control the piece which drops down.
Don't know how many Technics SLP110 are still out there but that's my story.

Technics sl pd-827, how to elect single cd?


This is straightforward. You have to ensure that the disk is stopped by pressing the square symbolled button then press disk skip once or twice and open the tray. Presto (if it is working correctly)

CD tray got knocked off track


You can try to fix mechanics by takin apart cd, remove tray and try open/close operation WITHOUT tray. Leave it as OPEN, then try to place tray back in fully open position, but be careful, you have to pres OPEN and then unplug it from outlet to avoid electric shock risk. BE CAREFUL!!!
