Since these devices are old with no new replacement parts, salvaging working parts is a valid repair option!
Check out the video for details, but it basically boiled down to:
- Removing the rear casing
- Disconnecting the flex cable that leads to the front lid and display components
- Removing the front lid
- Put the new lid in place and connect the flex cable
- Replace the rear casing
- You should now have a fully-functional unit!
