since a Sharp Quattron HD TV (52 in) my WII does not the pointer on the screen

[Casper100]

Since I got a new Sharp Quattron HD TV, 52 in. it seams that my Wii can't work properly with the new TV. Sometimes I get to see the pointer (Little hand) on the screen but it is very hard and you have to constantly move your hands until you get lucky and get to the starting button. I try with the other NOT HD TV and it works fine. Somebody told me that it's something related to the HD factor but the truth of the matter is that I have tried syncro again a couple of times, changing batteries by nothing seams able to get the pointer somewhere in that big screen.

Can you help me please?

Thanks
