It's not the tumi tsa lock is it? Because if it is, there's a video for that

How to open / reset a TUMI TSA Lock when you lost the number

If it's the regular bag lock, I would just start at one end or the other, put on the TV, and one by one give it a try.

There's a lock picking instruction for Samsonite here (which I seriously doubt was sent from Samsonite) which may also apply if they use the same type of lock
