Touchscreen display on HP Envy 4520 Series no responding

[ROTB]

My HP 4520 Series printer touchscreen display is not responding. How do I fix this issue? I have already disconnected the power cord and restarted the printer but that doesn't work. Not sure what else can be done.

Welcome to HP Forums, 

This is a great place to get support, find answers and tips to your technical queries.

To provide you with an accurate solution, I'll need a few more details:

Are you facing this issue after an update?

Have you tried any troubleshooting steps on your own?

I suggest you do a Hard Reset

(1) Turn the printer on, if it is not already on.

(2) Wait until the printer is idle and silent before you continue.

(3) With the printer turned on, disconnect the power cord from the rear of the printer.

(4) Unplug the power cord from the wall outlet.

(5) Wait at least 60 seconds.

(6) Plug the power cord back into the wall outlet.

NOTE: HP recommends connecting the printer power cord directly to the wall outlet.

(7) Reconnect the power cord to the rear of the printer.

(8) Turn on the printer, if it does not automatically turn on.

The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.

Wait until the warm-up period finishes and your printer is idle and silent before you proceed.

Let's update the firmware for the printer using this link: https://support.hp.com/us-en/product/hp-envy-4520-all-in-one-printer-series/5447920/document/c029191...

Restart the printer.

Keep me posted, how it goes!

This seems to be the only advice ever given. It does not work and I cannot update the firmware because the touch screen is not working to allow me to go into the settings.

@ROTB,

It looks like you were interacting with @Raj1788, but he is out for the day & I'll be glad to help you out, 
I'm the Jeet_Singh & I'm at your service. 

After reviewing your post thoroughly, I would suggest this to be a possible hardware failure. I would suggest you go through these links here: 

Link 1: HP Printers - The Printer Display Is Blank or Black

Link 2: HP Officejet Pro 8500 Printers - The Touchscreen Does Not Respond(Though the header is different but the steps mentioned should work for your printer as well).

If you have followed these steps and still having the issue, then its a possible hardware failure with the printer. I will share you few details through a private message about the service options dedicated to your product, please watch your inbox for more information.

I hope this helps resolve this issue completely,

Regards,
