HDCP can be one cause. If you would like to try some things, it would be worth swapping out your HDMI cable. In some cases, a longer cable such as 10-15′ might actually help. If you are connecting through an AVR, you could bypass it for a bit to see if connecting directly to the display alleviates the issue.
TWC typically has everything but the local affiliates using tuning adapters so I am afraid you may be out of luck trying to shed the TA. For the black screen with audio, the TA will not hurt/help the issue. The TA is only involved in actions involving tuning.
