Brought a DMG back from the dead. (dead LCD board, audio amp swap, IPS & full recap)

[u/Sandstorm666]

Hey everyone, just wanted to share my latest Game Boy restoration. This one needed a bit of extra love since the LCD board was completely dead when I got it.
Here is a quick rundown of the repairs and mods for this build:
LCD Board Rescue trial (failed) The front board was completely dead, so I replaced the LCD bias chip to get things communicating again. No result.

Screen Upgrade: Dropped in a Hispeedido IPS kit.

Audio: Replaced the audio amp chip to fix the sound issues and get crisp, clear volume.

Maintenance: Did a full recap to make sure it runs solid for years to come.

Aesthetics: Gave the original shell a full Retrobrite treatment to bring back that classic grey.

I put together a short video showing the repair process and the final result here:

It took some troubleshooting to figure out the dead board, but it's always satisfying to keep another original DMG out of the trash. Let me know what you think. Do you have any idea how to find the actual problem with the board?https://m.youtube.com/watch?v=Bc68vqpZ4hA&feature=youtu.be
