Many users have had problems where their power goes out and the Wii ends up killing itself. A fix they have done was to plug the Wii into an outlet with a "RESET" button. Pressing the button would reset the circuit and fix the Wii.
If this doesn't work, you could always call up Nintendo for a repair.
I was skeptical, but I tried the recommended fix anyway.
I plugged the power supply (only) into a GFCI outlet that I had tripped with the "TEST" button. I pressed "RESET" and removed the power supply's plug from the wall.
Thank you so much for posting this fix! You saved me a lot of aggravation and more than a little money!!
Can get them on amazon for about $10 that where I get most of my stuff from. Here the link for the site and item.
Our WII game was dead...and I was not happy! It happened after a power outage during a typical nasty summer south Florida rain storm.
I pressed the test button on a GFI recepticle (use one in your bathroom or kitchen), plugged the WII game in, pressed the reset button on the GFI recepticle...and THE GAME POWERED RIGHT UP!!!!
We were on our way to Best Buy to purchase a new unit, but decided to check this forum first as a last resort. THANK YOU THANK YOU THANK YOU!!!!!!
