I'm the type of person that doesn't like to waste time, so when I turned on my Wii on Friday and found the System Menu not loading, I wasn't in a very good mood. I knew I was going to have to spend a little time getting it to run again. At first, I thought it was a custom theme that totaled it, so I went to Preloader and installed a new theme. No luck. Then I wondered what the heck I did exactly the day before. I haven't messed with the system NAND, Wads and stuff lately, so I was kinda confuzzled as to why this happened. I tried unplugging (basic reset stuff) and nothing. Thinking that the NAND mysteriously messed up somehow, I used BootMii to restore my Wii to a previous state.
...that didn't work either. That is when I realized I was going to have to open my Wii again.
I heard issues of the Bluetooth messing with the System Boot if it was messed up. Sure enough, my Bluetooth module was fried. So I went got myself a spare Wii Bluetooth module I had lying around, installed, and got the wii to work. So I assembled my Wii again. After all was done, I boot my Wii only to discover the console would turn off after about 2 minutes. Here I go opening the Wii again...
I re-assembled the Wii like 4 times because I couldn't figure out the issue, and all seemed fine as I was close to putting in the last screws. In the end, the Wii had a red light when connected, but wouldn't turn on. I left it unplugged overnight seeming as this was a common issue (and solution) for many. Next day (today) I checked and nothing. Later I realized, upon the final dis-assembly, that something was short-circuiting the motherboard (hence the fried bluetooth). I noticed this when I plugged in the Bluetooth module while the power cord was connected. The Wii gave me an orange light, so I started to pin-point the problem. When I held the power button whilst the orange glow light was on, I heard a "click-click-click" sound somewhere on the Moherboard. Then at one point, it stopped and the Wii was working fine again. I figured the short-circuit was probably caused by something stuck inside the board, probably a nasty little roach (tiny one?). Whatever it was, the power of electricity got rid of it, and now the Wii is working fine again. Since I used a NAND restore, I gotta add some custom stuff that got erased, but the Wii works fine now. I added some new parts to my Wii in the Process. A new Wi-fi Module, Disc Drive cables, and a new heat-sink.
*My next step is to learn to solder Wii NAND chips, and I'll be able to fix complete bricks
