I have the following fault on a 6600: Hardware Failure - Restart Camera

Has anyone come across this at all?

From looking around the forums this does happen, but know one has a any repair hints! I have changed the camera unit, but the same problem happens. I assume this must be a PCB problem, but has anyone a cure?

I also have on the same phone a sound problem, so they may be linked? When you insert a headset into the jack plug and fiddle about the sounds work OK. When nothing in the sounds do not work. I again have changed the connector block, so not an obvious problem.

Any help would be useful.

Thanks
