/diy/ - Do It Yourself

>>2023363
OK, so I took a break and came back, and decided that since I have a ton of game boys, maybe I should look at another working one. Turns out, I dunno if it matters really, but the revision of my working model was CGB-CPU-05 and my broken one was CGB-CPU-04. I found another working unit that was CPU-04 and found something funny; A spot where I got some odd resistance behavior on the working CPU-05 (working 1), which was + terminal to this little board at point 1, was fully continuous on working CPU-04 (working 2). I checked the same spot on the broken unit and found it was a dead connection. So, I wired a line directly from + terminal to the point 1, and wa la~, fucker turns on yet.

The only problem I'm having is, well, it doesn't turn off. The switch doesn't do anything, it's just always on once the batteries go in. I tried desoldering the connection I had made from + terminal to the switch and found no change (which at least means I can remove this wire) but it doesn't really answer why the switch isn't working. Anybody able to give me some advice? Pic is board as it is now, prob gonna desolder the loose wire next
