My tv is acting strangely after there was a software update (sometime between April 10-15,2024) randomly turning off and on -- many times within a few minutes remote works some of the time or only certain buttons goes to a colored screen i.e. purple, yellow, light blue with no image just color sudden annoying continuous, high pitch sound like an alarm Checked and reset the cable box and called cable company. Unplugged and plugged tv back in. Change the HDMI input It is becoming very frustrating.
