Guitar Hero World Tour

Okay, so I haven’t really played guitar hero in a while and we recently moved our wii from the downstairs tv to the up stairs tv. This is the first time I have played the game on the upstairs tv. When I played the guitar hero on my downstairs tv about a month ago it worked perfectly fine. I had no problems wiith any of the 2 guitar hero games I have. But when I went to play the games today I had a problem.

I’m fairly good at guitar hero and normally I can play most songs on Expert. So just to warm up i started playing "Smoke on the Water" on hard. And I couldn’t play it. I would strum and hit the note but it would say that my timing was off. So just out of curiousity I started playing on easy. I could hit the note, but there was a great delay. Like I would hit the note and 3 seconds later it would register that I hit it. This is find I suppose on easy, but on hard it really messes you up. I don’t know how to fix the problem though. I moved where I was sitting. I moved the sensor strip around. I trying switching out batteries in the remote with new ones. I tried using a different remote, but the problem is still there.

Extra information:
I have a guitar hero guitar for the wii, that’s what I play on

I have the games Guitar Hero 3: Legends of Rock, and Guitar Hero: Smash Hits.

A friend gave me an idea and said I should calibrate the wii guitar to my wii, but I can’t figure out how to do that.
I tried calibrate lag and that didn’t work… it made a really loud high pitched noise on my tv, so I stopped doing that and restarted the game. and I don’t think we have an HDTV.
