GameBoy Color EM10 Choke Repair

date published : January 12, 2015 read time: 1 min

One of these days, my old GameBoy Color suddenly stopped working, I notice that EM10 circuit is broken.

I ask for help in subbreddit r/AskElectronics and according to the schematic EM10 circuit is a general choke (ACM4532-801-2P).

01

The battery pack negative it's connected to the power connector ground, which is then routed to the choke. So if the choke is broken the GBC won't work.

I short battery negative with board ground (don't judge my welding skills 😅)

02

It's working!
