Mother board does not provide power on battery port to charge it
I have 2 gba sp having the same issue, it is not charger, or battery related, neither fuse F2.
Dunno where to go to, to find out how to repair it.
Symptom : short red/orange light flash when pluggin it on the charger.
Then when controlling the battery port, no power at all or almost nothing 0.0….
I have been changing battery, charger, and swapping with other gba sp that run ok as expected.
Can’t find out.
I have been trying to test transistor on the mother board and could find 2 without continuity, but, comparing with other gba sp working well, it is the same.
I’m lost !
Thanks a lot
