I had a problem with my Wii and Nintendo wanted over $120 to repair the console. After some web browsing I found an excellent repair manual at Wii Fix Guide- One Stop Solution to all Wii Problems

I managed to repair my Wii from the instructions given and at a much reduced cost.
Just thought this may help anyone with similar problems.

cheers!
