I have cox cable. When I go to signal diagnostics my over the air channels have good signal strength 89, SNR (db) 30. However when I switch to cable my diagnostics gives me nil numbers.Signal strength zero, SNR N/A,. Would you agree the signal is getting lost from my cable box output to the tv input. Cable guy says its not their problem because they can reset my box remotely. A remote signal to reset the box is not the same as a incoming video and audio signal. My question is the signal diagnostic good to check incoming cable signal.I have never used it when I had a good signal.
SOURCE: Cannot get a connection with HDMI input
When the tv won't scroll to the HDMI inputs, it means that the tv does not detect a signal on those inputs. This either means the tv has an issue and can't receive an HDMI signal(very unlikely) or there is no signal being sent from the source(converter box) The first thing I would do is unplug all output connections from the box except for the HDMI output and see if this gets rid of your problem. If not, I would be more inclined to think you have a problem with your converter box than with your TV. You could also try using the HDMI ouput of a DVD player if you have one.

The problem is that, according to the specs for that TV, it doesn't support 1080p.
That's a 720p television you've got. (Specs here)
While the specs say that it supports 1080p, the resolution says it supports 1366 x 768, which is only 720p, not 1080p or even 1080i.
You may want to contact Sony for clarification, because their specs for that tv are contradicting each other.

Well, your TV is still under warranty. That's the good part.
The only thing I can recommend without voiding the warranty is leaving the TV unplugged for 30min. That way, the TV can reset itself and hopefully correct the problem.
If that doesn't solve the problem, it's time to use the VIZIO warranty.
Here's contact info if you need it.

After reviewing the service manual for this set, the problem is is in the DIGITAL BOARD. To get the right Digital Board you will need the Version number of the TV.
Good luck

I have the 1525 and you have to do extra steps each time you want the HDMI to be recognized by the Bravia - too bad it is not automatic as it is with some. Anyway what you have to do is have the HDMI cable connected from laptop to TV then go to your desktop - right click on an open area (away from icons), a menu will appear, let the cursor hover over Graphics Options - you'll then see Output To...then you'll see Intel Dual Display Clone...hover over that and you'll then see Notebook + Digital Television...left click on that and you should see your desktop on the TV in a few seconds. If it does not work the first time...get your movie or whatever you want to show up and ready and go thru these steps again...stupidly complicated aye? when it should automatically detect and show...are other TVs like this?
