Chosen Solution
So about a month after I got a Nintendo DS Lite motherboard and installed it, It would not turn on or charge. When I plug it in, the charge light turns on for about a second and then turns off, and when I push the power switch up, Nothing happens whatsoever. Both fuses are good(0 ohms), and L2 reads fine, there is continuity between the power switch and pin 12 (PWSW) of the power management IC. I have another DS Lite motherboard that will charge but will not turn on (both fuses good), and the game card slot is taken off. So I have a parts motherboard if I need it. Help will be greatly appreciated because I really need to do my daily Brain Age.
If you’re absolutely positive you’re F1 & F2 fuses are good, double check the soldering job on the charge port. There may be only 1 pin connected or it’s lifted somehow. Beyond that, keep testing with a known good working battery. Generally, I’ve found, that if there is no green power light coming on, it’s either the battery, charge port, F1 or F2 fuse.
