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?
