Wii Component Cables...

[Wii_Master]

So I have Intec Wii Component Cables but soemtimes when I turn n my wii the sound works perfectely...But nothing comes up on the screen.I take out the cables and hen plug it back in and then only it will work.. 

What should I do??? and no there is no problem with my TV....I got a Sharp 46" LCD 1080P TV which is Absouletely awesome and guess what Sharp told me that on my TV With component cables it will show in 720P....This feature is also available in select Bravia TV's...
