# Repairing Canon Pixma MX925 - may loose connection on the cable? - one of the LEDs comes on - but screen not coming - just stopped working - left on in sleep mode in between prints > To try and resolve this issue, please unplug the power from the unit for about 25-30 minutes. Once this time frame has passed, plug the unit in directly to a wall outlet to see if the display will power up properly. It's been off for more than 30 minutes… ## Resources - [SOLVED: Why is my mx922 not powering up? - Canon Printer - iFixit](https://www.ifixit.com/Answers/View/348152/Why+is+my+mx922+not+powering+up) - [MY PRINTER JUST STOPPED.
