no probs.

Have a really good torch handy.
The alignment marks on those pillars are fkn hard to see.

Oh, and if you need to turn the posts, you can just 'lift' them a smidge to free them from the gear wheel teeth.

But I say again, WATCH THOSE F01 CAPS AND SPRINGS.

well the stripdown/allignment/rebuild went very well without loosing the small parts.

still no joy with the unit though, still getting e/mecha but the intersting thing is when i press around the cn107 area it starts to reset itself then cuts out randomely.

so it looks like i need someone with micro soldering skills because mine arn't too clever with a 25watt soldering iron :smash:

Don't wanna sound like a smart ar-e.
So I won't say anything :clown:
 
Even though I have surface mount and reflow experience, first time I saw the connector I shuddered.

After the tenth I was, meh, nudda one.

Between the first and second I got the 0.3mm solder.
Made a world of difference.

Best of luck to ya...

Oh, the first one I did, I umm, damaged some tracks.
Ended up using a single strand of thin wire to remake the tracks.
Whole lot is glued down now.

Oh yes, some of the later boards had a drop of black or white 'glue' placed along the edge of the board to try and secure the connector better.
By the number of those I did I don't know how effective it was :cannotbe:

well i did a bit of soldering to day with my new "micro" soldering iron and now when i reset the unit it goes a bit further, below is a link to a video i took, still get the e-mecha error as soon as i press the source button though...

something about that puck in your picture looks differant to mine, not what if anything but i have a hunch 😕 also, it's never possible to insert a cd because the 2 little tabs are always in the "locked" position...

thanks, mark.
 
Damn! That could be what is wrong with mine!
I heard this "rattling" around inside when I bought it (during shipping).

Inside i found the puck. I thought it went on TOP of the black plastic one. It seemed logical!

Now it looks like I will be tearing mine open again!

Thanks!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Maybe, just maybe!!
 
She's Fixed!!!!!!!!!!!!!!

I am so elated I can hardly stand it!!

MaddMutt, you ROCK!!

You posting the picture of the "puck" was the key! I had "replaced" into the wrong spot.

Of course, don't blame me, I had no diagrams and couldn't find anyone to even WORK on Nakamichi. I understand they suck for service.

Please email me, MaddMutt. I have something for you! ($$ hint).

You just saved me a boat load of frustration and you taking the time to post here was the key to my sucess!

Thank you!...
