Yamaha YPG-225 Display Replacement

Introduction

Use this guide to install a replacement keyboard display.

As the face plate is no longer connected to the body of the keyboard, be careful to not drop the body when performing this step.
Flip over the keyboard

Lifting from the front and the back of the face plate equally, pull the face plate up and then back, away from the keyboard.
Be careful when removing the face plate. There are wires attached.

Locate the main circuit board - it should be toward the middle of the detached face plate.

Using a flat head screwdriver, carefully pry up the beige ribbon connectors and remove the wires from them.
Use a slightly upward force with the screwdriver as parallel to the ground as possible.
Be sure to make a mental note or jot down the locations of the specific ribbon cables. Some are in close proximity to each other and it can be easy to forget which ribbon goes where.
Be sure to unplug the smaller ribbon that connects to a different circuit board.
Take care not to use too much force. The connectors are fragile, the ribbon wires are easily bent, and too much force may damage the circuit board if you happen to miss.

Move the ribbons out of the way and remove the eight 10mms crews in the middle that hold the circuit board down.
Remove the two 12mm screws in the corner of the circuit board.
