HP Photosmart D110a Motherboard Replacement

소개

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.

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.
