Hi Mark,
Unfortunately this is a hardware failure, and the C2 Swich is "end of support".

Hi Fred,
We do not support any products purchased through ebay!
We only provide warranty service to the original purchaser.
And without maintenance contract we do not provide any firmware to customers
Regards
Engin
