Ricoh Aficio MP C7500 (D015) No Display

[zeeaxis]

Dear All,
I have a Ricoh Aficio MP C7500 in my workshop with no display on LCD or no engine run and scanner movement. it doesn't do anything except after a couple of seconds start key turns red. Please advise me if it has anything to do with electrical wiring or something else. any kind of help is appreciated.
thanx in advance.

Shine a flash light across the display and see if there is a SC code showing. You can also try to access the WIM to check for SC codes.
