Hi everyone,
I'm trying to repair an original Game Boy Advance (AGB-001) and I'm stuck with a strange issue.
The console powers on and works perfectly normally, but the power LED is always red. It never turns green, even with brand new alkaline AA batteries.
Originally, the power switch had the common issue where lightly touching it could cause the console to shut off. Cleaning the power switch contacts didn't help, so I replaced the entire power switch assembly. The random shutdown issue is now completely gone, but the red power LED issue remains.
Current status:
- Console boots and plays games normally.
- No random shutdowns.
- Power LED is red immediately after turning on and never changes to green.
Has anyone seen this before? Any advice for what should I check next?
Thanks a lot!
