My wii was constantly locking up (freeze ups) nearly and I was unable to play wii sports cause of this. I was looking on the internet of how to fix this and someone mentioned taking out the cmos battery. Long story short I ended opening up my wii and touched something I shouldn't have and now getting black screen. Everything works, it's just a black screen. I can still access bootmii via boot2 and I've restored a copy of the nand to it but hasn't help. Can you please help me?
