Unless you are using a streamer in which case you need to change your HDMI cable or reseat it. I should also point out that broadcast TV through antenna, cable or satellite dish is rarely higher resolution than HD which often works on a tv with the resolution set too high as the tv usually defaults to the resolution of the media being broadcast
The picture is so bad babies killed themselves. 😂
I had a similar issue on my TCL TV. What fixed it for me was going to advanced image settings, looking in clarity and changing the gradation clear to low or off.
I would say those dolls are possessed by the devil and they are trying to send you a message.
Go to manufacturer's webpage choose your model and get the instructions to reset to factory defaults. They may also have an update, do it.
If it didn't work contact support. TCL have a great support. They will ask for a lot of things, like photos, movies, information about the device, etc. But if it's a faulty device they will change it or return full money.
If it’s Google TV my chrome cast does that sometimes til it’s rebooted.
Unplug the power from the TV for 2 minutes. If that doesn't fix it, then you have have installed a corrupted update. Maybe try patching the latest tv updates and see if that fixes it. Last resort is a factory reset
Is there option to downgrade, maybe that helps
It looks like the video chip on the built-in Chromecast is a problem. If you still have a guarantee then they should replace it for you otherwise I would just buy a Chromecast and plug it into the HDMI
You probably have the resolution set too high. Streaming apps often use lower resolution automatically to save bandwidth. Which is why they work for you
