Cxx0 General discussions / C860 Charging Problem (not Battery)

« on: March 16, 2006, 05:45:00 pm »

Well, at last my C860 is fixed.

My .750mA fuses arrived yesterday and this evening I took the whole thing apart. Breaking the case open wasn't pleasant as I wasn't sure where the clips were. I ended up sliding my thumbnail along the joins.

On mine, the 2A fuse was fine, but the .630mA was blown. When removing the old fuse I was worried that I had broken the solder tag for one end off the PCB. Just to be sure, I added some extra solder to the pad on the new fuse (I lost four fuses just trying to get them out of the packaging!). I then spent about an hour convinced that I had run solder onto the neighboring components as they seemed to have continuity with the fuse. Then I realise that they're probably the components that the fuse protects, so of course they're going to be connected! Just to be sure I took a hi-res photo with my Digicam in macro mode, which convinced me that the soldering was good.

One word of advice to C760/860 owners. I disconnected the wide ribbon cable as I didn't want to stress it. I recommend you don't do this as it's a real b*stard to get back in the socket!

So at last after 2 years of owning a dud Zaurus (it was sold to me as working by an ex forum member!) it's now sitting there happily charging away. Now I've got it working I have no idea what I'm going to do with it, but I guess that's the fun part  

Many sincere thanks to Maslovsky in particular for making this repair possible.....

Well I've had no luck getting any samples from Koa or Littelfuse  

Koa never answer or anything, and Littelfuse always redirect me to Farnell or RS Components when I order samples, neither of which supply a .680 Amp fuse.

Anyway I gave up decided to buy some 0.5, 0.75 and 2 Amp 0603 fast acting fuses from Farnell. I'll see how I get on with the 0.75 Amp fuse first. I guess if it blows up and destroys the C860 then I won't really have lost much as it's sitting in a cupboard anyway!

If anyone finds's a retailer stocking these, please post here and I'll pay to buy a load of them, then we can send them out to whoever needs them. Likewise if I find a source I'll post it here.

Hi Cgrieves, I was wondering if you've managed to find the fuses - I'm in Woking and desperate to get my hands on them too... I can't for the life of me find anything on the Koa Speers / Littelfuse websites    Could you guys let me know where you got the fuses or perhaps post a direct link on where they are on those sites? Pretty pleeeaaaase .

Hi Nataliya, sorry about the lack of reply, I haven't been here for a while!

Anyway I have tried reordering samples from both Littlefuse and Koa from their websites. I did all this before but never recieved confirmation, and nothing ever arrived. If I have any luck then I can easily send a few out to you- I've requested 25 of each fuse from each site. I'll let you know.

Wow, thanks Maslovsky, I think you have just made an awful lot of clamshell owners very happy indeed, including me! in fact I haven't felt so happy since we won the ashes

I will see what I can find in terms of components. 0603-packaged 2A fuses are very easy to find, but so far I haven't found any 630mA, only 500mA and 750mA.

If anyone finds's a retailer stocking these, please post here and I'll pay to buy a load of them, then we can send them out to whoever needs them. Likewise if I find a source I'll post it here.

Cheers!

My c860 is not turning on.  I didn't think this to be a battery issue until I read your post.  Even when my Z is plugged into the wall outlet, it will not turn on.  Do you think that could still be a battery issue?
[div align=\"right\"][a href=\"index.php?act=findpost&pid=91547\"][{POST_SNAPBACK}][/a][/div]

The C860 seems to need a bit of charge in the battery before it will turn on, even while on the AC adapter. If you are plugging your adapter in and the charging light is coming on but not charging the battery, then I suspect you may have the charging problem. Trying another battery or using an external charger is the only way to be sure....

Also see if you can get into the service mode (press D & M while turning on).

General Discussion / Battery or recharge circuit problem - C860

« on: June 22, 2005, 08:28:51 am »

Well, mine have been repaired in japan by the store I buy it from (Brando) ... as it was still under warranty I just had to send it back to brando who then managed to get it repaired and sent it back to me for free ... now it's fried (again) as my girlfriend have done the same error as me , reverting the DC polarity and I'm hoping too to find another way to repair it as it's not under warranty anymore :/

Just redirecting anyone with charging problems to this thread:

[a href=\"https://www.oesf.org/forums/index.php?showtopic=11539&hl=]https://www.oesf.org/forums/index.php?showtopic=11539&hl=[/url]

Here's hoping Maslovsky can come up with the repair information!

Code: [Select]

My Zaurus:
 Â  Charge off: 3.0V
 Â  Charge on: 2.5V
This is easily fixed by replacing a few capacitors. Afriend of mine did that a few times.

Whooooooaaaaaaaaa there cowboy!

I think this is the answer I am looking for.....

Maslovsky, my friend, my best friend....   Is there any chance you can get some more info on what caps we need to replace? I'm have access to decent solder/desolder gear so this might solve all my problems!

There's a reward in it for you (can't think what yet, but we'll think of something!)

Cheers!

Seva did you ever have any luck getting your unit repaired or replaced??
[div align=\"right\"][a href=\"index.php?act=findpost&pid=80550\"][{POST_SNAPBACK}][/a][/div]

No, I've been pretty annoyed by this and haven't sent it back yet.

I'll try today.

OK just wanted to keep this thread alive. I have a friend who emigrated from the UK to Japan some years ago, and apparently his girlfriend is a bit of an ogre..... apparently she never keeps receipts or boxes for electronic good, and when something goes wrong with an item, she goes into the shop where she thinks she bought it, throws it at the assistant without box or receipt, does a bit of a strop, and 99% of the time gets the item replaced. Not very ethical I know, but I am going to ship my C860 over to her and get her to try it.

Worth a try.

I am also going to try and get some info on how to get in touch with Sharp Japan.

Let me know if you have any joy with yours!

I'm going to try and get my C860 repaired once and for all, even at cost, but I need to find some way of getting in touch with support at Sharp Japan, or another company that can undertake the work. Anyone got any ideas?

The first thing you should do is pack it up in a jiffy bag and send it to this address.....

« on: May 19, 2005, 12:48:35 pm »

Sorry to bring an old thread back from the dead, but it seem this is the only source of info for Cx60 users with truly fried charger circuitry....

Has anyone managed to repair the faulty charging circuit? Alternatively has anyone outside of Japan had their units repiared for a reasonable price?

I'd love to make my C860 usable again so I can ditch this 'orrible IPAQ!
Cheers!

General Discussion / C860 not charging/warranty-need to contact Sharp

« on: November 02, 2004, 07:15:28 pm »

Thanks for the replies- I have done a couple of quick pictures of the documentation that I got with unit (apart from the manual). The A4 sheet looks like an advert for a wifi card of some description. Can anyone tell me what the others are?

Incidentally the smallest form has a sticker inside which says "World Electric Company Co. Ltd"- could that be the receipt?

General Discussion / C860 not charging/warranty-need to contact Sharp

« on: October 27, 2004, 05:32:59 pm »

Hi there, I bought a C860 from a ZUG member. I love the unit but it turned out to have the charging problem, and as such is next to useless for what I need it for. Now it seems I have been left high and dry by the seller, so I need to contact Sharp Japan in order to find out what my options are to get it repaired. Does anyone have any email contact addresses for Sharp Japan that will accept and respond to an English email?

I have the Sharp Warranty cand, but unfortunately no idea who the original vendor was.....
