intermittent Latest software update broke HDMI on my LG OLED G2?

[OliverRC]

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?

I have experienced the same issue with Denon AVR3400H.  I’ve seen other posts along this line and hope there is a patch by LG to remediate!   It’s a large inconvenience as base LG oled sound is not terrific.

I just posted about this very topic. Have you found a solution? TV keeps saying no signal no matter which port used (trying to connect our cable box) diagnostic says faulty hdmi cord to ALL that we’ve tried. Makes no sense. And yes this happened after update.

Hey, for some reason I haven't experienced the issue very much after posting it. If it does happen the only solution that seems to work for me is to hard power off the devices (i.e. turn them off at the wall) and then turn them on again.

I am not sure if they ALL need to be powered off, you can start with just doing the TV but mine are all on 1 plug so they all go off an on when I cycle the power.

It sounds like you're having a frustrating HDMI problem after the latest software update. Other users have faced the same issue, and the only solution for now seems to be turning the devices off and on. It's not the best fix, but it might help until LG releases an update. Let's hope they sort this out soon!
