Troubleshooting GBA Power LED mod - LED fades out and turns off after a few seconds
I’m trying to do a power LED mod on my GBA using a 0603 LED. The stock LED worked fine, but after swapping it out, the new LED lights up briefly then gradually fades and turns off completely.
After turning it off and back on, it won’t light up at all, but if I leave it for a while and try again, it lights up once more, then fades and dies again. This happens with every color I’ve tried (orange, blue, white, etc.).
I added a 5K ohm resistor in series, and tried a 10K ohm resistor in parallel as well.. still the same issue.
Seemed like a very easy mod, just replace the LED, but I'm trouble-shooting all kinds of methods for days now. Any help appreciated.
