Tower is not coming on, can i bring it in and get a new one the same day?

Yes. Usually anyway.

Call before you go

Whatever equipment you bring in you'll get a new one right away, make sure you bring identification so they know the account is yours.

I suggest that you make sure the plug is plugged into the tower as well as plugged into the wall. I I am not sure if Optimum will give you a tower the same day, I witnessed Optimum give a new remote control the same day
