Chosen Solution
I have a DSi, and a logic board from my DSi back in 2009. I opened the back of the DSi, and disconnected all the ribbon cables and unscrewed all of the screws on the logic board. I replaced the DSi’s logic board with my 2009 one. I powered it on and the bottom screen flashed for a millisecond. So I took out the 2009 logic board, and put the original one back in. Tried to power it on and no blue light, and the screen is black. It had a solid charging light. I had another logic board that I got from eBay and put that one in the DSi. There’s no blue light, and the charge light blinks on and off. I tried it with multiple batteries and these problems are random and happen with all 3 logic boards. The DSi was working fine before, and I don’t suspect a top lcd problem, because I was extremely delicate with the ribbon cables. Any help?
