I have 3 toshiba 3100's that the fiery's go into boot mode intermittenly after warm up, this happens most commonly after install, or it just won't boot up at all ? Anybody have any ideas, I sent one (fiery) to have it repaired the standard cost to repair these babies are 900.00......it's getting a little old. Is there a firmware or reformat that I am not using that can help?
