I have a customer with a mx2600. You turn on and the sharp logo just spin longer than normal. after a minute display come up. but you cant do anything. no please wait or ready. I tried new memory no luck. replaced mfp board no luck. thinking hard drive or program chip is bad. Any thoughts would be helpful. I know you have to get program chip from sharp so they can program the chip. I believe its the rom chip. thanks
