Re: Buzz fix attempt, tomorrow
Hi all Thanks Yoann for the pictures. I just looked at them, and I have the same question : what is the other component you solder on the right side ? Is it for repairing a previous unattempted desoldering ? ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Hopefully, the fix that we made works. -- Yoann. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

I'm not sure if anyone would want them though, since the capacitor was so hard to place well. -Steven Hi Steven, A thought - as an alternative to using a camera, find a scanner/photocopier multifunction device gadget thing, and stick the circuit board on that - it creates much better images. Some of them have a scan to pdf or tiff, and then fire it to an email address or ftp server - that's what we've done here.

Before diving into trouble water, I would really apreciate some feedback on your attemp : Oh yes, I have to do that. I want to make a useful report but I have no time for this * did you succeed ? Yes, but it was very very hard. And my fix is very ugly. * is the buzz canceled ? Yes :) * have you taken photographs on your work ? Yes, but they are poor quality. The coponents are very very small and I had to be close to the phone taking the pictures. I'll try to make the pictures available tonight. Just an advice. Be aware that the coponents of the phone are very small (about 1mm) and it's very hard to desolder just the resistor and not the other neighbour coponents (I desoldered one conensator...) and it's harder to solder the new components. (that's why my fix is ugly because we had to repair that) -- Yoann. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
