Guys. I need your help badly.
I have MPC 2500 which shows no display after boot up. The motor is running as well as the other mechanisms.After a couple of minutes the red light indicator in the printer mode and error indicator show. When you press any buttons in the 10-key, it beeps. When you touch some area in the touch panel it beeps also. I replaced the power supply unit, BICU board, and the I/O board but no luck. I checked the operation panel in the other working machine and it is working fine. I also checked the controller board and it is good also.
I will try to replace the high voltage board tomorrow but I doubt it.
Any ideas about this kind of problem? Please help!
