With the description you give, the first thing I think of is..
Some of those chips may be EEPROM memories, and they get erased with the light..well infrared light to be more precise, and only if you remove the cover stickers I am just guessing though, I have little information on what actual chipsets you're working with.. or if these phones use EEPROMS at all...
Other thing is you're not using static electricity grounding, and the electronics of the equipment has been damaged, but again, I might be wrong. You might be an expert (or knowledgeable or carefull) in handling the chipsets...

I've searched high and lo and googled to I can't google no more... I knew that Cisco bought Selsius to get their VoIP solution but what I didn't know was that the 12sp+ is based upon an ITE-12 product that is apparently used at universities. I've taken two of the phones apart and started swapping parts and have looked up the IC's on the Internet...
Anyway... After using the phones with chan_sccp the phones die for no apparent reason. No LCD. No nothing. About the only thing the phones do is make a static sound when the handset is lifted or speaker is pressed. Can't get the phones to work again. I've tried everything I've found. I've even blew the dust off my CallManager 2.4 CD's and loaded the phone images on my TFTP server. But once the phones go dead there is no more IP traffic from them.
Normally I would assume that the phone is beyond repair but nothing is happening to the phones. They just stop working. Last one that stopped working happened today. Left it on overnight and this morning it was dead.
Anyone have any ideas.
