LG 55" 75 Nanocell T.V 2021 model powers off when using shield T.V Pro. " FIX "

[NANOCELL1]

I just purchased an LG 55" 75 NANOCELL T.V about 10 day's ago. out of the blue on day 8 when I would switch from HDMI 1 to Live T.V the T.V would show the T.V broadcast for about 1 second and then the T.V would turn off. so I I did the plug unplug then I messed with energy saving features timers so on so forth on the LG, but to no Avail could not get it to stop shutting off when I would switch Inputs.  so I am scratching my head??? I was to the point of returning the T.V to the place of purchase as I am still within the return period.  So I think Maybe it's a CEC/HDMI power function issue on my Shield T.V Pro.  "I am not sure if this is a random bug or not, and why I am posting this here." it may be an an LG and Shield T.V issue".  So any way the "THE FIX" what I did was go into settings on my Shield T.V Pro , select Device Preferences, then select display and sound, then select   Power control, I then ticked each option to off, and then reboot the Shield T.V and VIOLA!! no more issue with the input issue, I then went back into the  BOX and turned each one back on one at a time until I could find the one preference  that was causing the issue,  "it was the option sleep shield when T.V input changes" that was the culprit.!!!! I hope this helps anyone that has had this same issue!! keep it off it's not needed for most
