Sounds like you need an 8520. I blew up several of these getting my
Epson LX-810 to work (power cycling the printer did the nasty deed).
To get the Par: port back I swapped the two 8520's and found that my
clock went dead, just like yours. Lesee... (quick look at the schems)
Looks like U7 is the culprit. Try swapping them first and see if the
problem migrates.
