everythung was fine last night. Tonight when I turned on the tv the screen was blue displaying "weak or no signal" I thought perhaps the source setting got inadvertently switched. When I tried to switch it back, using remote for the tv, the screen scrambled and I could not get it to go back to blue. The tv sound was on with a scrambled picture. No matter how many other things I tried , re setting, turning off and back on , running through the troubleshooting list, I even tried to use one of my other uverse boxes from another tv in the house, (all other tvs working fine) nothing seems to work. Now I have a scramble screen and can't get the sound back either. I've made a bigger mess of a mess. Please help

If you tried placing another Uverse receiver at this location and still have same problem, the issue is not Uverse.
Now try changing port if have multipleHDMI ports to choose or try changing the type of input cable being used such as HDMI instead use component.
Issue is cable itself, cable loose, bad port on TV or TV itself.

@Diane1633 - I would like to reinforce MTs recommend to use component cable. It does sound like he HDMI is not working.
Look up in the TV user manual how to connect component. IT has five cables - three video & two audio. If you have any old composite cables (red, white, yellow), you can use them for the three video connections. Just be careful to get the colors the same at each end. Then use any stereo cable or the red/white of a composite cable for the audio.

@Diane1633 - 50 ft is a long way for an HDMI cable. Not to say it would not work.
For u-verse to work, it needs to see an HDCP signal from the TV. If it does not see that signal it will not provide video output. The 50 ft HDMI cable may be adequate for the conrtent signal , but noot the HDCP signal.
Sometimes for testing, you need to set up different than you will use regularly. I would connect TV/STB with a short HDMI cable to see if it works. If it does not work - try a short component cable. Also, try different HDMI inputs on the TV.
Never saw a long component cable. Long HDMI is availlabe & also a splitter intendend to extend length - https://sewelldirect.com/sewell-hdmi-1x2-splitter-v13b?ad_source=googleadwords&ad_medium=ppc&ad_term...
