If the box doesn't have HDMI it can't send HD to your TV because it's not an HD box. Call your cable provider and they will exchange you old box for a new HD box with HDMI.
The set-top box performs decrypting function and u can't do without it, typically, if you are using a cable service.
As usual, you don't disclosure where you are, so in the per chance that your cable provider still sending you QAM signals, u can hookup inbound coax directly to the TV.
