Bizhub C650 display won't come up. HELP!

[Keystone2]

We shut our C650 off to check the transfer belt & when we powered it back
up, the red & orange lights go on, but the display is dead. Happened 2 months ago,
but came back up. Is there something we can check to make it work?
Thanks for your help.

Usually one of the memory modules is getting knackered. I'd try that first!

Thanks & how do we check & fix that? We're "do-it-yourselfers" & not techs. Much appreciated.

you should check the firmware update usb slot maybe if the cover is open the machine is looking for usb memory.....

Re: Bizhub C650 display won't come up. HELP!

Is that the large, flash card slot on the right side of the machine?
My partner did remove the fuser & put it back in, just before this happened.
Could that have caused a problem or maybe the sequence he turned the
sub & main power buttons off?

sorry i just read the c650 ...if you remove the left cover at the back of the machine and then the mfp protective shield which is about 15 screws you get to the mfp board. try removing the memories and put them back in. it's like a simple motherboard. i guess one of the memories is faulty...

THANKS! I think it worked. We got the hour glass on the display & looks like its booting up.
I'll know in a few. Wish you were located in Reno as we need a tech to service our machines.
Much appreciated & thanks again. Buzz

We now have the hour glass up on the display, but its taking really long for the machine to boot up.
Is there something else I should do?

Re: Bizhub C650 display won't come up. HELP!

did you just remove and reseat the memory ?

If bad memory is in bank 0 machine will have a blank black display with an orange start button and both LED's on on the scanner and wont boot any further
If bad memory is in bank 1 machine will start to boot but will lock up once it attempts to utilise the ram in bank 1 (short time after startup)

If you have swapped the ram around, you have just confirmed that the ram is indeed stuffed.

Yes we did swap the ram. Does that mean we have to buy new ram & if so, where do we get it & is it
just the ram 1 or ram 0? (left or right stick as we're looking at it?)

Should clarify that the top ram slot is blank, with no ram & it was the bottom two sticks that we swapped
with eachother. Can we buy ram at Best Buy or is it a Konica Specific part?
