Turner channels pixilation

I have been dealing with pixelation for more years than I can recall. Still happening after all things changed/replaced, including...boxes, modems, routers, wires, coaxial, drop lines, tv's, splitters, amplifiers etc... Go to your main box and turn on tv. Press and hold exit button for 5 seconds then immediately press down arrow twice and immediately press the #2 button. This will bring up a diagnostic screen. Go to summary then in-band Network. Power dbmv #'s should be around -7 to 7 closer to zero the better. and SNR power around 40. Then go down to system. Look at DOCSIS. Downstream power near 0 is best but -7 to 7 should still be ok. SNR above 35 is good, higher is better. Upstream power between 35 and 55 dbmv is normal.. Post numbers here if they are way off. This will give an idea of what may be an issue. Just fyi, my numbers are all in spec and yet I still have a pixelation issue but it's not too bad, just a nuisance. Never on streaming. Pixelation is caused by many things. Loosen up the coaxial on the box and wiggle it and you will replicate the problem. So yes a loos cable can cause it, but so can a bad box, line interference rat chewing on a cable, on and on it goes.

Hey there, @joeferg22. One of our community members provided some great insight to viewing your signal levels for the box. Have you gotten a chance to follow their advice and check those out? Posting those here would provide some insight into what is possible affecting your TV picture quality.
