Well, unlike me, it sounds to me like you understand the wizardry of electrickery so if it could be the solder that fails is it possible to re solder the unit? If you, or anyone else feels that it would be something that could be attempted I would be happy to donate my failed camera to try to "Frankenstein" it back to life. If it proved to be a positive result then maybe there would be a nice little service there for members on a sale and exchange basis.
