JB Recorder won't charge

[bruemmel]

Hi,

from one day of another my JB Recorder 20 stopped charging.
(OK, it felt from a table.  )

When i plug in the power cable it shows - after initializing - "Archos Jukebox Recorder Batterie Charging" as usual. But after some seconds the "Batterie Charging" vanishes.
When I plug in while the JB is running the plug-symbol vanishes after a few seconds.

In both cases the batteries don't charge !!
The only chance to run my JB is to charge them external.

Has someone an idea how I can fix this ?

Thanks a lot.

I suggest you have a look at this page:

Thanks for the fast reply 
Yesterday I openend the Recorder but saw nothing broken.

But with the knowledge where to look after, I will do it again this evening.

I did it again. The JB is open !
But the two solder joints are not broken. And that's what I mention when the JB is running. There is no loss of batterie-power - at no time.

It is impossible to charge the batteries in the JB - no difference whether the JB is running or not.

OK. You could try to replace a chip called MC34063A located below the keypad, on the lower end of the top PCB. Also check that the DC connector isn't broken.

I had the disappearing problem too, couldnt charge or power it on any more using Rockbox. I think the problem are just the batteries that are out of power so Rockbox hasn't got enough power to run. What worked for me is charging the batteries a little while using the Archos firmware (press F1 when putting in the power plug) After charging for about an hour your ajb should power up as normal with Rockbox. Don't know if the problem is the Rockbox charging or the batteries.

  oops, that's beyond my abilities. i think now i have to call the archos service.

.... or power it on any more using Rockbox.

I tried it with F1 and the JBR seamed to charge some seconds longer. But then it stopped charging again.

By the way: I have no problem to power on the JBR. It's the charging which don't work.

OK, that's it. Everything's workin' fine.

I just tested the power adaptor with an Voltage Meter: 7,7V. But then.... I read "NOKIA" on the buttom. ....  Shit ....  I tried to charge my JBR with my CellPhone-Adaptor 

THANKS A LOT FOR YOUR HELP !!!!!!!!
