cannot use damaged tv coaxial

[JustMe615]

cable company sent 2 boxes. LR and BR (not set up yet)
could not get many channels or HBO and was told by comcast rep that it was the wrong box for the tv. coaxial cable will not work on my damaged tv, so i need to go through hdmi but the box has no other options than colored L and R ports. Any idea what to do?

You were told it's the wrong box, why don't you get the right one from them?

You WANT to go through HDMI, that's the best connection possible, why would you want anything else?

Ask provider for a set-top box with HDMI OUT. You are paying for it, may as well.
