HP Print and Scan Doctor cannot find LaserJet Pro; touch screen black and unresponsive

[DeeMacLi]

Hello!

I have the HP Color LaserJet Pro MFP M283fdw Printer. I'm having three problems that I suspect are interrelated. The problems:

1. The touch screen is black - it does not respond to touch. I've power cycled the printer several times, to no avail.
2. The Printer is "Offline", and I cannot get it "Online" again.
3. In order to fix these issues, I've downloaded and run HP Print and Scan Doctor several times, to no avail.

What I've tried:

• As stated above, I've power cycled the printer several times. I've followed the power cycling steps posted elsewhere in this forum, including plugging the printer directly into the outlet (not in a power strip), and holding the power button while unplugged to ensure a full discharge. Of note, when powered on, the printer does make the normal "start-up" sounds.
• I've downloaded the HP Print and Scan Doctor tool. The app could not find my printer - I tried all three connection methods, including USB, Network Wired, and Network Wireless. For the USB connection, I plugged directly into the computer (not a hub), and tried numerous different USB ports on the computer, as well different USB cables.
• In regards to the Network Connections, I powered cycled my router, for the sake of thoroughness. All my devices receive a "strong" to "excellent" signal from the router, and none of my other devices have connectivity issues.
• I've ensured that I have the most recent version of HP Smart.

Some other notes:

• The printer was purchased less than a month ago. (Early July 2021)
• The printer was used less than 10 times.

My suspicion is that the printer (the touch screen, perhaps?) is defective. Any ideas on how to get it working?

Thank you!
