MZ-NH900 Disc wont eject, spring problem !

[MD4ME]

Hi, The spring on my MZ-NH900 no longer ejects the disc, how easy is it to remove the casing to get at it ? I've taken the screws out but there seems to be a knack to actually releasing the casing from the main body (unlike older models which were easier)

Whilst on the subject of the MZ-NH900, is there a cure for the common problem of the 'cancel' button forwarding the tracks ?......Cheers !

Sorry, I can't help with the eject problem.

I'm now on my third NH900, after the first two suffered from malfunctioning buttons.

I never found a cure, but I found that if I pressed a button numerous times - say 100 or so - it seemed to alleviate the problem for a few days. Once you get quick at it, it only takes a few seconds.

Having revived an N505 with exactly this (button) problem, I can be reasonably sure that the difficulty with the buttons is resistance/cleaning. You need to get it apart, and to spray some contact cleaner into the buttons themselves without getting it all over a. the outer lid and hence making the unit sticky and smelly for a while b. any of the mechanism. I don't think one has to be a rocket scientist to encompass this - however the procedure is not for the faint of heart.

The commands to the unit depend on detecting changed resistance (same thing with the remote). If they are dirty or there is poor voltage from the battery, you will see this. One clue that it is the case is if you find it always does better on the charger than just with the battery. Even take the internal battery out completely, and just try it on the charger, to see if I am right

The eject may be as simple as the main case screws are too loose or too tight. It's also possible the spring that the clamshell must be pushed again to close it has popped out. I suppose it might be broken, but I would guess that displaced is more likely. Not sure how it got like that, though.
