I have a strange issue with a 1708 controller when powered by battery. Wired it works fine, but on battery the light only starts flashing when you press and hold the X button. Once you let go it turns off. I've tried the same batteries on different controllers, and also fresh batteries, to no avail.
Nothing seems off on the board on inspection. Any pointers as to where I might start looking or how to troubleshoot this?
I've traced the battery line to around Q7 and Q6, and everything seems in order up to that point.
I did a search already and haven't found anything similar, but apologies if this is a repost.
