Thank you for helping. I did try all of your suggestions. Unfortunately, i have had no success.
I have never had an

TV run through the Onkyo before. The Onkyo is only 2 months old.
I went out and bought a 4k HDMI and still no luck. This is my 3rd HDMI cable.
I have tried running the

TV through the Cab/Sat and still no picture.
The only place i can get a pic is when i run it directly through the Samsung... I can't do this b/c i wouldn't get the surround sound.
Any other ideas!
THANK YOU for your help
OK, so here's the big test (which you may have already tried):
- If you are pumping your cable box into the Onkyo via HDMI cable and then from Onkyo to the TV via HDMI cable,
- turn on your system and get a cable picture on screen,
- unplug that HDMI cable from the cable box and plug it into the
TV. Turn on the
TV.
Any

TV picture?
This eliminates a LOT of variables (2 HDMI cables, how the Onkyo input port is set up, TV input is set to the proper jack, etc). Basically, if the cable box can show a picture on your TV by routing through the Onkyo, the

TV should definitely show a picture when you leave everything as is and just switch THAT same HDMI cable from being plugged into the cable box ad plug it into the

TV instead.
If it doesn't show a picture, then I'm thinking there is something wrong with your

TV.
Yes, I understand that when you hook it up directly to the TV, it shows a picture but I still suspect the

TV needs to be swapped out if you try the above and can only deliver a picture with the cable box.
I'm guessing you are feeling a temptation to just hook the

TV up to the TV but it should work perfectly fine to hook it up to the Onkyo. Receivers are supposed to be the "hub" for ALL audio-video equipment, not just some of it.
Also, your message implies that you might have a prior-generation

TV. To test my guess about a faulty

TV, consider doing the exact same test by inserting a prior generation unit in place of the cable box. Does IT show a picture? If it doesn't either, then I start thinking the Onkyo probably has some kind of issue.
