I don't think the chip is dead, but there could be a bad connection somewhere inside the player. or it could be the firmware got corrupted.
Afaik the Kpac never got any firmware released so trying another firmware would be risky.
You could try posting the board and screen number for sfw1 and see if he could find a matching firmware from an unbranded player, but I would only try this if you get desparate as you could kill your player.
