How to detach plastic tray to replace a CDJ-700s DWY 1069 Lens?

Hi Tony, you should also, explain how old is your pioneer cdj 700s. I hope you have done all what you could.

May be your player have lived his life and its leaser needs to be replaced.

Not sure, but it may be related to the optical assembly... it´s always about the optical assembly lol... Does it display any error message?
It can also be something wrong (bent, broken, too much dust) with the blinds-like mechanism where the CD lays down (closed when lid is opened, opened when the lid is closed). So if it can´t "see" the disc, either by a problem on both mechanisms, the spin motor doesn´t starts.

Liberty electronics on ebay have now the ultra-rare DWY1067 optical assembly. Have a check at the sticker on the back of your 700s player, above the barcode. If it was manufactured until 2000-2001 you´ll probably need a DWY1067. After that, you´ll need a DWY1069.

Probably your optical unit is worn. If you 700s are the newer ones, it'll be easy. Unscrew the 4 black screw under the unit to release the cover. Is the optical unit is exposed, check the label over it. If it says DWY1069, you'll only have to replace it, readily avaliable on ebay. It can be found very cheap ($15-$25).
If it says DWY1067, you have a big problem like me. 1067 is out of production. Check my other posts on how i'm trying to solve it.

Hi, try cleaning the lens with a cleansing disk. if this doesn't produce results, it will confirm a major issue within the lens assembly. you will need to replace the lens assembly in this case. it is unable to track or read in this damaged sate.

Hi Marcelo. I´m from Brazil, same CDJ-700s, same problem as yours. From what I´ve researched until now, DWY 1067 an DWY1069 ARE NOT FULLY INTERCHANGABLE on CDJ-700s and maybe 500s. I think some newer 700s already came out with 1069 from factory, so this is why all this misunterstanding. On older 700s that came out with 1067, some SMD components must be changed in the mainboard in order to 1069 work properly. Mine came ou with 1067, I´ve replaced it with a 1069, didn´t worked well (sound skipped, or didn´t play at all).

In 2001 Pioneer released a replacement kit for this situation. The kit is named GXX1200, and includes the optical unit (DWY1069) which is included in the whole mechanical unit (DXXsomething, depends on model), and SMD resistors and capacitors for replacement. Dirty job, I know...

Since I already bought the replacement 1069´s, I´ll buy the SMD components too. I´ll let you know if will this work. Not an easy task, but I´ll try.

Here you can check the whole kit:

Does it show the error number ? Something like "E 9101", i don't remember the code exactly. If so then it's 99.9% that it's a mechanical problem. You can try shaking the turntable, or dissasemble it and try to open the lens doors, just don't break them!

Hi Je remy
I have a 700s too, it´s showing problems similar to yours. Mine is even worst, it almost doesn´t play no more (shows "NO DISC"). Sometimes, when i turn it off and on, or open the cover, it reads... When pause is pressed, it holds the music for some seconds, then it "slides" thru the music... Sometimes it display an error message (something like E-8something).
I think all these errors are caused by a worn optic reader, but i´m not sure. I´ve already opened my unit and cleaned the lens, but no bail.
Here in Brazil a new optic reader can be found for R$150 (around U$90). I´ve just found out the same unit in UK for 150 pounds, so i´m suspicius that those units sold here aren´t really new... I´m planning to replace mine, but first i must be sure that the problem is really caused by the reader.
I don´t know if u have already opened yours, but it´s pretty simple to replace the unit, just some screws to loose (12, if i´m not mistaken - 4 ouside, 4 holding the lens protective cover, and 4 holding two inox sticks where the reader slides over). 700s´ units are Part No DWY1067, and you probably won´t find those anymore. You´ll only find the DWY1069, originally found in CDJ-100s (technically almost same, but probably some newer technology), but they´re totally interchangeable.
Hope could be of some use.

Error 9102 is a disk read error, and you either have a damaged reader or there is something seriously wrong with the tray unit causing the error. Troubleshooting is not that simple for this unit, you will need a multimeter, and possibly an oscilloscope to trace the error. More than likely, you will need to have the tray replaced if the error persists.

Error 9101 is a read/tray error. More than likely your reader/pick up tray is faulty, and will need to be replaced. For the CDJ700, cost for a new pick up assembly is about $75 - and not an easy fix. Lots of stuff to remove first. Kinda like a car. To get to 1 section, you have to remove 3 others.

Hope this helps.
