Default SANYO SF-P mechanism in NAD 52x cd-players

I have two NAD CD-players with SANYO mechanism and the same problem. After the CD load the mechanism stays in lowered position. I have no idea how the mechanism works and what is broken. Help!

The small belt close to the front panel? There is one belt only ? Both - the tray and the mechanism plate are driven by this belt?

maybe, if i'm not wrong is the same mechanism that has the denon dn-d4000 and dn-d4500, they are double cd player dj style, very fast mechanisms, kinda reliable, but still if you post a picture of the mechanism or much better a video on youtube i can tell you more accurate about it

I know only this NAD models from that series:

1) NAD 5220 (and 5225, but include RC) - Sony KSS-152A inside
NAD 5220 - ok or too old?
2) NAD5320 (and 5325, but include RC) - Olympus TAOHS inside
Yamaha CDX-1110 - Worth modding? (post #9)
TAOHS : who is the manufacturer ?

The most models are the "502", "512" and "514". There are Sony Laser heads from the KSS-series inside (KSS-210A, KSS-213C).

Which model is yours? Perhaps the 522? from the attached picture?
Then the datasheets about
http://www.commonways.com/?cid=78287...=Front_loading
and
http://www.tradeeasy.com/supplier/42...mechanism.html
can help.

I have several CD-players in non-working condition. The 522 is one of them.

Mean you the 52x series or the C52xBEE series?
If that Sanyo mechanism from the picture is inside, datasheets must actually be help.

The 52x, not BEE series. I have the service manual, but the picture does not explain how the loading mechanism works. Could you make it out?
