Samsung smart tv

I've had that happen with a bad HDMI cable. Since, they're cheap, that's the first thing I would try.

My Samsung smart TV of many years is connected to my 10 year old HDMI cable to my laptop and so far no problems with image. I also sometimes use ROKU, Amazon, and Chrome streaming devices with no image issues plus use a DVD/Blue Ray DVD player frequently.

Yes my HDMI cable is at least 10 years old as I bought it from a Circuit City going out out of business sale in central Texas.

Have you returned the TV to factory settings?

Can you do a total reset on the tv back to factory settings? How do OTA channels look if you can get them?

Connect the TV to something else and see if anything changes. Antenna, computer, DVD player, something.

I connected to my iPhone hotspot and colors are good. So it’s probably the hdmi from hopper to tv?

This is what I have done for repeat problems. It is also what the manufacture suggests first and most often.

I did the reset and it didn’t help. On WiFi/Tubi the colors are fine. Must be the hdmi from the hopper.

I bought a new Samsung last year and had the same problem, except I used it for streaming only. WIFI, No HDMI. Returned it and replaced with VIZIO. Great picture, but they have their own set of 'smart tv' problems.

I seriously doubt it's the HOPPER but.. not impossible

More likely the HDMI cable.. I've had issues with cables causing color changes. But hold on. Alas I'm do not understand HDMI well enough.

In the old days.. I knew how to fix that. But that was then. Modern flat screens don't have that issue (Stray magnetic fields that need neutralizing)
