I have a problem with WorkCentre 7220 that does not want to boot up. When I turn the machine ON, the LCD screen says that the machine is booting up, but after about 10s it goes blank. The ? LED blinks and the machine stays in this status.
The 7-segment display shows error 6 (which indicates HDD issues, but HDD seems to be OK), LED's CR3004 and CR3005 are ON (RED), which indicates issues with U3011 (Winbond 25q80bva1g EEPROM).
I tried replacing the HDD and re-flashing the system with AltBoot process, but the software upgrade process did not start. There was no difference in the boot process when the USB for AltBoot process was inserted and the machine rebooted.
The system board looks OK, all voltages are looking good. So I think that it's a minor thing, perhaps so minor as failing U3011. Does anyone have any suggestion what else to try? Is it possible to get a new pre-programmed U3011?
A new system board is too expensive, so if I don't solve the problem, the printer will go to scrap. Which is a shame for a printer that is just over two years old ...

The Xerox tech came and said that replacing the system board is the only way to go. But like I said - system board is expensive and replacing it is not feasible any more on a 2 year + machine. And since I have good electronic background, I still think that a system board repair is possible. I just need someone to guide me to the point of failure ...

Thank you very much for the hint. ;)
But from what I can see, PWS load requires special Xerox software, which is not freely available.
If anyone has any information where to get the software that is required to do PWS load, please share.

As fiery stated, you need a Xerox tech to service it.
Even if someone could get the PWS software, there is no way they could provide it to you here, it is not public software.
