Question about HP DeskJet 890c InkJet Printer
What can i do to troublshoot, the power cord is good
The things it could be: 1. There may be a failure of the switchmode power supply inside or a fuse on the printed circuit board has blown.
2. The ON/OFF button is not making good contact. Again, this would need the cover off and clean any contacts - try to short the contacts. Find a electronic or computer technician to help you with this. Maybe buy another second-hand, working unit, and use the original for spares.
