The HDMI port on my Motorola DCT6416 suddenly stopped working.
The composite Video still works ok. Searching for HDMI failure on that
model comes up with plenty of hits (seems to be a common problem),
but I cannot find anything on what the exact component(s) are that
fail. I opened it up and checked for any visible problem, but didn't see
anything obvious.
Has anyone dealt with these DVRs or can provide any idea of what's
involved, or if it is even worthwhile trying to get it fixed? Thanks

help, and my cable provider couldn't (or wouldn't) tell me where they get
their rented DVRs repaired. Since I own the box, I phoned around for
estimates, but none had ever fixed any of these, and so they told me that
the repair cost would likely be higher than buying a new one.
If I knew for sure that a particular chip was defective, I would probably
try replacing it myself, but I think it makes more cost-efficient sense to
just get another one. Appreciate your reply.

The DVR menu says HDMI ENABLED, but not ACTIVE. The re-activation didn't
