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.

Up until a few days ago my TV and AVR have been working perfectly since I bought it.
Zero hassles with HDMI and connectivity.
Then I was prompted to update to the latest software version which I did and now often when I switch HDMI (running on 1) it picks up the device name, CEC works but I get “No Signal”… and then nothing.
Just stays on “No Signal”. It is almost as if some HDMI handshake breaks and now the driver is in a broken state.
I’ve found that if I hard power off and power on the device sometimes works but I don’t want to do that every time especially since it’s hard to get to the power.
This really strikes me as a software issue with the latest update as absolutely nothing else has changed in my setup.
I’ve tried:
Different HDMI cables (high quality) Deep colour settings Reset the TV to factory default Different HDMI ports TV
Model: OLED65G26LA / OLED65G26LA.HFBQLWK WebOS TV Version: 8.3.0.2301 Software Version: 13.30.56 AVR & Devices
Marantz SR5015 Nvidia Shield Pro PS5
The setup is the conventional AVR installation as shown in the attached file
Has anyone else experienced this?
Is it possible to revert the software update?

webOS updated, I think to 2023, on my C2 a couple of days ago. Since then the News option on the Sky News app no longer works, instead timing out. The Weather and Climate options still work, though.
I have deleted and reloaded the Sky News app, but the problem remains.
Does anybody have any suggestions of what I might try to get this working again, or is this something for LG, or Sky, to fix?
