MP C307 has blank screen

[Chummy]

Can anyone help with a MP C307 that has a blank screen with only the blue power light on in the top right of the control panel ? The fuser warms up but the machine won't print, copy or scan. Any suggestions.

I'd try accessing Web Image Monitor to look for any alerts or error codes, but I suspect it's a faulty controller

Could also be the ops panel main board.

I agree with TonerMunkeh.
Usually it's the Op Panel that has crapped out. We normally send ours into Hytec for repair as this is cheaper than buying a new one.
If you have a good donor machine, I would try swapping the op panel to see if that is indeed what it is, and if that doesn't solve it, then you may be looking at a controller.

Thanks for the info given so far. I will be returning to the machine later this week and will use the info given for further investigations. Thanks again.

Thanks for the update.

Interesting that this stopped the machine from printing.
