I've had the same problem, the guitars for this guitar hero are terrible, they were apparently rushed by Sony; ive researched the problem and apparently you can get a "dongel" or something, it's supposed to keep it connected, look into one.

You may have seen this already, but I went to RedOctane.com and found the instructions listed below. It looks like that if all of your attempts fail, you can request a warranty replacement. I really hope this helps in your guitar woes.

Try the following:

• Verify that your guitar is connected to the PS3 by looking for the red indicator light above the strum bar.
• • If the indicator light is not lit please refer to the following page for directions on how to sync your guitar to the console.
• Try disconnecting and reconnecting the wireless dongle, then restarting the system.
• If the buttons are not functioning in the game or behaving oddly please press the lever on the back of the guitar at the base of the neck and remove the neck from the guitar. Then plug the neck back into the guitar.
• Check to see if the guitar button in question is functioning in the Playstation 3 XMB (the strum bar should scroll you up and down, the fret buttons act like the buttons on the controller and are labeled on the side of the neck, etc)
• If the strum bar is registering extra hits try keeping a finger on the strum bar while playing the game instead of flicking it with your fingers/hand.
• Try replacing the batteries in the guitar.

It seems that the recent PS3 Firmware update (2.80) reassigns your controllers. In order to fix this (I just did it 20 minutes ago and all is fine) is:
Go to the XMB "Settings" Menu.
Open "Accessory Settings"
Using the controller you want to reassign, open "Reassign Controllers"
Scroll to the number you want that controller to be (1,2,3 or 4)
You are good to go!

Thanks to the Phone Help at Activision for this fix!
