Thanks. In the meantime, I played around some more with the remote to see if I could find the specific buttons at issue. Channel buttons 1 and 7, channel up, sel, skip forward, and the light switch all don't work. A very random set of buttons. When I push those buttons there is no response by my tuner or cable box. Other buttons work fine, but the problem seems worse now (more buttons and even less responsive) than earlier this evening when I first posted.
