I did something stupid out of curiosity. I took a 9 volt battery pack and tried to power on the system and charge it using the leads on the console. Now it won’t turn on (as expected). Is there any way i can fix it now or did I shoot myself in the foot?
Board repair is the kind of things that if you need to ask, you can’t fix it. So it’s more like shot yourself in the head instead of the foot.
