HP Officejet Pro 8620 Display Replacement

Difficulty

Moderate

Steps

Time Required

10 minutes

Introduction

Follow this guide to remove a faulty display in your HP Officejet Pro 8620. If the touch-screen display is unresponsive, has image burn in, or stuck pixels you will need to replace the display.

Tools

Step 1

Place the printer on its back and rotate the display clockwise to gain access to the underside of the display.

Step 2

Locate the control arm on the underside of the display. You will need to detach this to access the screws.
Place a finger behind the control arm.
Separate the display unit from the control arm by pulling down with your finger and using your other hand to push the display unit up.
Removing the control arm takes a moderate amount of force.

Step 3

Remove the four 11mm T9-Torx screws on the underside of the display unit by rotating the screwdriver counter clockwise.
Open the display unit to expose the circuit board by separating the back and front panels.
Remove the ribbon cable by gently releasing the plastic locking mechanism and pulling the cable away from the circuit board.

By pushing the display to the left with a little force and then up you unlock the whole part that is containing the LCD screen. Then remove the ribbon cable. The unit is now free and it is way easier to remove the four 11mm T9-Torx screws

Remove the four 7mm T9-Torx screws from the circuit board that are holding the screen in place using a T9-Torx screwdriver and turning counter clockwise.
Lift the circuit board/screen panel from the black frame.

Conclusion

To reassemble your device, follow these instructions in reverse order.
