Why isn my wii system turning on?
First, check your cables and power feed. Also, if you’re trying to turn the Wii on using the Wii remote instead of using the power button on the console itself, be sure the batteries in the remote are not dead. If everything is okay but it’s still not responding, unplug the Wii from power and allow it to sit for about 10-15 minutes. Plug it back in and try again. If the unit will still not operate, contact Nintendo customer service for help. Fortunately, Nintendo has a stellar reputation for customer service.
