Recently, my Wii will not play on my tv. I have sound but no video and my tv says "no video source." I have replaced the AV cord but still have the same problem, making me think it’s in the Wii. Is there something I can do to fix this myself or do I need to take it somewhere? If so, who fixes these types of problems??
my DVD player works fine!

 can I fix this Wii problem myself?
