HP Photosmart D110a Motherboard Replacement

Difficulty

Moderate

Steps

Time Required

20 - 40 minutes

Introduction

If your HP Photosmart D110a (also known as HP Photosmart D110 series) is experiencing symptoms such as failure to power on, persistent error messages, connectivity issues, or irregular operation, the motherboard may need replacement. A faulty motherboard can manifest in various ways:

Printer won't turn on or stays stuck on the startup screen
Control panel unresponsive or displaying error codes
Unable to connect to wireless network
Print jobs failing to process
Scanner or copy functions not working

Before proceeding with this repair:

Verify the issue isn't caused by software problems by performing a printer reset
Back up any stored printer settings as they will be lost after motherboard replacement
Ensure you're working in a static-free environment as the motherboard is sensitive to electrostatic discharge
Disconnect the printer from power and remove any installed ink cartridges

This repair requires careful handling of delicate ribbon cables and electronic components. While not technically complex, it's recommended to attempt this guide with 2 or more people to help manage the printer's weight and components during disassembly.

Required Tools:

T-9 Screwdriver
Needle-Nose Pliers

Tools

Step 1

Pull down both front panels to open the printer. Lift the scanner flap upward by pulling down on it; there are two mouth pieces that need to be pulled down.
Adjust the flap covering the scanner upward, as shown.

Step 2

Pull the scanner flap gently away from the printer to release its two clips.

Step 3

Locate the three screws on top of the printer.
The orange circle shows a fourth screw located behind the power panel. Ignore this one for now, as directions to remove this screw are in Step 5.

Step 4

Using a T-9 screwdriver, remove the three screws from the printer's top.

Step 5

To remove the power button panel:
Reach inside the printer's front opening.
Press the small clip behind the power button.
A picture of the power button panel removed is provided to show the location of the clip that needs to be pressed.
Pull the panel out from right to left.

Step 6

Remove the fourth screw, which was covered by the power button panel.
Do not try and torque the screw from an angle. This will ruin the screw's head, and make it even more difficult to remove the screw. Only remove it as already described.
This screw is placed awkwardly. We found holding a T9 bit in a pair of needle nose pliers gave us enough leverage to pull it up.

Step 7

With a partner's help:
Have one person lift the hood 2-3 inches.
Have the other person disconnect the three cables from the motherboard (the green PCB) to the hood by gently pulling upward on them.
Remove the hood completely.

Step 8

Once the lid is removed, the motherboard (the only green PCB board) will become accessible.

Step 9

Use a T9 Torx Security screwdriver to remove the three screws securing the motherboard.
With your fingers or a spudger, remove the cables and ribbon cable by gently pulling them free from their sockets.
