Bizhub C451 Won't Power Up

Where are the "memory sticks" located? I only see memory modules on service manual part no V865-3000. Thanks again.

Memory modules, memory sticks, that's them. Appears to be standard PC-3200 512mb laptop memory, although I used pulls from another machine. They're located on the MFP board near the top.

you can generally tell which ones dead by the symptoms.

bank 0 - machine will do nothing at all, black screen, LED's are on on scanner thats about it.
bank 1 - machine will boot but will lock up rock solid at any point upto and including the ready screen.

Good info, thanks. From that it would appear that bank 0 was defective on the unit I was servicing.

Got it. I will give it a shot and provide an update when available. I sincerely appreciate the help.
We were an NEC dealer which brands these Minolta units, but NEC went under and away went our call center tech support.
Anyhow, thanks again.

Alright guys removed memory placed existing memory back on boards and the machine came on to Ready screen. However the control panel is unresponsive.
It will not take any commands and start button is red. Zero error codes are present.

SOLVED

As mentioned before defective memory chips removed existing, swapped with new, and the machine is back to normal.

THANK YOU ALL!
