New tv install problem
New Insignia brand 1080 smart tv hooked up with HDMI cable doesn’t seem to retain the signal from the U-verse box. Tv displays mostly static with flashes of a proper 4:3 picture then a picture with black sidebars.

Have you tried a different HDMI cable? Have you tried disconnecting and reseating both ends of the cable? Have you tried a different HDMI input on your TV?

Yes to all. I contacted AT&T support and they concluded it was most likely a bad HDMI port on my U-verse box. They sent a replacement box that corrected the problem.
