Bricked Doorbell?

My alarm.com doorbell seems like its dead. I have done all the troubleshooting several times but it will not fire up. Is there some contact information available for the manufacturer?

Thanks

Can you confirm the model of doorbell you are referring to? Are you saying it is completely powered down with no LED reaction?

Did you verify that correct voltage is being applied to the circuit? Check at the doorbell transformer for any broken/loose wiring.

After checking the above, if no luck, I would check with the vendor for warranty details as well.
