Color Laserjet pro M454dw display is black (not working)

[greezeuh]

My display suddenly stopped working. 

I tried updating the firmware but the file I can download from the HP site for this is damaged.

I tried unplugging and resetting the printer but alas.

Anyone?

Can anyone help please?

I just replaced the display but the new one also dont work.

Which seems to indicate the problem is somewhere else.

Any cables I should check?

Hi @greezeuh,

Welcome to HP Support Community.  

Thank you for posting your query, I will be glad to help you.

If the display on your HP Color LaserJet Pro M454dw printer is black and it has suddenly stopped working, there could be several potential causes for this issue. Here are some troubleshooting steps you can follow to diagnose and possibly resolve the problem.

• Check Power Connection: Ensure that the printer is properly plugged in and that the power outlet is working. You may want to try plugging the printer into a different outlet to rule out power issues.
• Restart the Printer: Sometimes, a simple restart can resolve minor issues. Turn off the printer, unplug it from the power source, wait for a minute, and then plug it back in and turn it on.
• Check Display Brightness: It's possible that the display brightness is set to a very low level or turned off. Refer to your printer's manual to adjust the display brightness settings.
• Firmware Update: Check if there is a firmware update available for your printer on the HP website. Updating the firmware can often resolve software-related issues.
• Reset the Printer: Perform a factory reset on your printer. This will return it to its default settings. Be aware that this will erase any custom settings you have configured.
• Check for Error Codes: Even if the display is black, there might be error codes or status lights on the printer that can provide more information about the problem. Consult your printer's manual to decode these error messages.
• Inspect Toner Cartridges: Ensure that the toner cartridges are properly seated and that they have not run out of toner. Replace any empty cartridges as needed.
• Paper Jams: Check for any paper jams or obstructions inside the printer. Even a small piece of paper can cause issues.
• Network Connectivity: If your printer is connected to a network, make sure it is still connected and has a valid IP address. You may need to reconnect it to your network.
• Printer Driver: If you are trying to print from a computer, make sure you have the correct and up-to-date printer driver installed. Sometimes, driver issues can cause problems with the display.

I hope this helps. 
 

Take care and have a good day.
