Re: HP Envy 4520 printer screen is blank/stopped working

@iam_Katy, Thank you for your response. 

Since your HP Envy 4520 only has Home, Question Mark (?), and Back (⤺) buttons, let's adjust the troubleshooting steps accordingly.

Try a Different Hard Reset Method

Since your printer lacks a Cancel (X) button, try this alternate reset process:

1. Turn off the printer.
2. Unplug the power cord from the back of the printer and wall outlet.
3. Wait at least 1-2 minutes to drain any residual power.
4. Press and hold the Home (🏠) and Back (⤺) buttons together.
5. While holding the buttons, plug the power cable back in and turn the printer on.
6. Keep holding the buttons for another 10 seconds.
7. Release the buttons and check if the screen lights up.

Check for Backlight Failure

Try shining a flashlight directly at the screen while the printer is on.

• If you see faint text or icons, the display backlight may be faulty.
• The printer may still function, but the screen is not displaying correctly.

Force a Test Page Print (Bypassing the Screen)

Since the display isn't working, let's check if the printer itself is responding:

1. Turn on the printer.
2. Press and hold the Home (🏠) and Question Mark (?) buttons together for 10-15 seconds.
3. If the printer reacts (beeps, moves, or prints), the issue is likely just the display.

Check for Loose Display Cable (If Possible)

• If you're comfortable, try gently pressing around the screen edges to see if there’s a loose internal connection.
• If you're comfortable opening the printer, check the display ribbon cable inside. A loose or damaged cable could be the cause.

Use HP Smart App to Check Printer Status

Since the display is blank, try accessing the printer via your phone or PC using HP Smart:

1. Download HP Smart on your phone or PC.
2. Ensure the printer is powered on and connected to Wi-Fi.
3. Open HP Smart, and see if the printer is detected.
4. If detected, try printing a Printer Status Report from the app.
   • If it prints, the issue is just the display panel and not the printer itself.

I hope this helps!
