Hi lkd543
Thanks for your post - and good to know Activision are admitting the best way to keep your instruments running is our repair kits (Activision support give out our details for lots of enquireies they recieve!)
Yes the solderless drum repair kit will be your best bet, What is probably happening is a bad connection to the sensor as deatiled in this
postYou can view the installation video and purchase a drum repair kit from
here, and we should point out that the repair kits are compatible with Guitar and Band Hero drum kits and the installation process differs very little apart from where the screws are located (they are not hard to find!)
Good luck
Steve
