I have a text on the upper left corner of the TV, had appeared about a week ago. It says VIDEO 1 How can I get rid of it?

Hi turn TV off at the power PLUG for about 5 minute's.& HOPE IT WILL LOSE IT'S
MEMORY ... cheers

I believe the "Caption Vision" is selected. By pressing the "Display" button on the remote it should toggle through the choices until "Display Off" appears. That should be all.

It is what we call a "Shatted Pixel" and you can fix it by flashing your screen

check your manuel, they should be a display button to press to get rid of it, a rectangle with a + in it on the button

Hi,
I was awaiting your response in chat session but could not get any thing.
Please hook cable box in Video input-7 instead of Video input-6 in TV and select Video input-7 with remote on TV.
Regarding continues on-screen display of video-6, press Display button on TV remote once, on-screen display will disappear.
Thanks.

Had same issue with my LG so I trouble shot the issue by noticing the green square would disappear if I switched to dvd(HDMI-2 ) Or HDMI-3. Which lead me to believe it was being generated by my Xfinity box (HDMI-1. So I first rebooted box. With no success I then unplugged box all together. Tah Dahhh! Problem fixed. Hope this helps.

have a "craig" tv and the word factory is on the upper left corner, when this word appears i can no longer use any

Press Display / Info button on Sony "original TV Remote" and on-screen display will disappear.

Tiny particles of dust on the light engine lens can cause this (and was a service call for me about a month ago), or possibly the expensive light engine.

If you have the original remote control, press display to get rid of it.
Hope it works.
