So, I was at a flea market some time ago and picked up a Wii for about $10 that the vendor said "wasn't working," but I decided to take the gamble and now I'm at a bit of an impasse. The Wii appears to power on just fine, but the only AV output is a black screen. Not "no signal," but a black screen. The console did not include an SD card so I have no way of checking for any traces of homebrew, and I'm starting to suspect that the bluetooth module is broken or misaligned. Any ideas on how to troubleshoot this?
