Okay, I have a DSi since 2010 (I don't remember when I bought it, so this could be false. Look, it's old. OK?) And it's been working fine untill one day. I turned it on, and the power light (blue in this case) turned on for a milisecond and then turned off. I tried it multiple times but nope. Plugging in the charger makes the charging light blink non-stop. So I tried opening up the DSi (I opended it up mutliple times before so the warranty is voided already. I also did it correctly the other times so opening it isn't the problem here) to find out what is wrong but I found nothing wrong in it! Sure, the ribbon cable connecting to the SD card is broken but it's been like that for years if I remember correctly. Battery was looking allright, took it out with a voltmeter, wasn't dead (Also, I doubt it static electricity because it wouldn't do ANYTHING). So, I closed it up and opended up the charger. Strangely enough, a piece of the charger's motherboard was cut off! Like someone took a bite! But how could I be using that charger for all this time and it was working. I won't use it again, defenitely. So I went to a store to try out the store's charger, it gets weirder. I plugged it in and the charging light flickered like before BUT, for only a couple of seconds. Anyway, I went home and couldn't figure it out what it is. Only thing I imagine is the charge port (the port where you put the cable to charge it, duh). I'm sorry if you cannot see the pictures very clear but my camera doesn't focus very well, and I'm not a profesional photographer to set the focus etc. So I'm writing now. Please help!
