Hello all and thanks in advance for looking and hopefully offering advice.

I've had my home theater setup for almost 2 years, no equip or version changes, no setting changes, and no problems. Here is what I have:

-Samsung 4671 LCD
-Onkyo 705
-Tivo HD
-Denon 1940 DVD/CD
-HDMI from Tivo and Denon into Onkyo, out to Samsung.
-Harmony 880 universal remote
-set up a 2.1 with Axiom LCR

One day while I was gone, my wife advised me the "TV froze up" and nothing worked...turned on but no signal. When I got home, and since, I have troubleshot every possibility...the TV and TiVO works fine with the TiVO HDMI directly connected to the Samsung...the DVD works fine for movies and music when I connect thru the Onkyo then to the TV...which is how I always had it.

The only function that doesn't work is the CABLE/SAT (TV) function thru the Onkyo. I get a 'No Signal' message.

I've swapped every HDMI cable and tried every combo of HDMI ports. They all work with the DVD in any location and every cable, but the TV/TiVo function doesnt work thru the Onkyo in any combo.

I've checked every setting I can think of on the Onkyo setup and all seems unchanged and no obvious "wrongs".

I'm stumped, and tired of switching back and forth. Can somebody please help? :-) I'd be thrilled to have an embarassing oops here...

Hard power reset of all equipment (unplug from wall power) for 15 minutes?

I've got it working...thanks!

I've got it working...thanks!What was the problem?
