I have a 2003 Panasonic TV with an HDMI connection. The new cable box has HDMI but won't work on my TV. Is there an adapter

Question about older HDMI

Did you try a different HDMI cable in case that is the issue? Also make sure the HDMI input is selected on the TV.

There is no HDMI to older HDMI adapter.

Yes, there are different HDMI standards, and a TV set from 2003 is most likely HDMI 1.0.
