My guitar from band hero won strum

Do you have the usb plug in that goes with the guitar?

You may need to dis-assemble the guitar to ensure that no damage has occoured to the strum bar internally as sometimes when this gets over used it has a habit to randomly strum on its own. Good Luck.

Have it serviced if its new it is still under warranty.

Remove the strummer by pullling upwards and outwards gently until you here a faint click. Either re-insert and try again or replace the strummer. Would probs cost about £10.

check your connection cords and if thats not the problem, try going into options and adjust the sound levels

If you got the Rock Band 2 guitar then you'll have the same problem as with the Guitar Hero: World Tour controllers. There seems to be a large number of faulty controllers. It is best just to take the controller back to the shop you purchased the game from and get a replacement controller. If you are feeling brave, you can take the faceplate off the controller and open it up to have a look at the connections on the strum bar, but you will void the warranty if you do. You can use the D-pad in the mean time to strum.

try callibrating tv game go to options>callibrate

this happens when the guitar gets used a lot. Idk if their is a warranty.

can uuse one from ather guitar the part from guitar hero they all should have same parts just differt desins

my scroll bar does the same thing sometimes, it moves up and down uncontrolably without me doing anything. i just recomend restarting and making sure the connections are all right. after i did that it seemed to work fine, but maybe if it keeps happening then you may need to replace it!!
