Same here with my tv. To reproduce, the screen must be all black first before toggle the audio for tv volume up or down

Yes correct. The best way to test it is to press the "TV" button on the remote, reproduce and check.

If Local Dimming is low and picture mode is "standard", the bar is very obvious from my angle and you need to sit closer to screen to see this bar. If you sit further say 6 ft the bar is not that visible.

updated the 2nd new VRR update for my X90H. Just found out today there is a horizontal banding when I press the volume button.

There is no problem in watching with any contents. Home menu also no banding. I wonder if this is a firmware bug or panel problem? Anyone has this issue after the update?

To me it's sounds like a software bug.

I havent tested on mine yet, need to figure out how to get the black screen, maybe from youtube?!

Ya most likely since all of us is experiencing it but one member here mentioned the technician who came to see his tv is going to change his tv's main board because of this issue.

After looking at the screen closer, yes I notice the line is on my screen too. The technician is going to replace your main board right? If it fixes the problem then I'm going to call them for repair as well.

I have the same problem too after updated my X90H to the latest software last night. Very frustrated now because my warranty is over. What should I do?!

On home menu, press "TV" button on your remote. It should go completely black if you didnt setup before. Then try to toggle volume button.
I would like to clarify. I called Sony Support, he took my warranty number info and etc and said a technician will be in contact with me to diagnose at my place.

The technician WhatsApp 2 days later for model and serial number details, asked me to take pics and videos and back and forth responds. He straight away concluded this is main board problem without coming to my place and informed me he ordered the replacement part.

Like I said I don't know any better so I just went with it. Since this is just a backup TV and not my main TV and I just had a newborn in the house  , I am not in a hurry to fix the TV even cause its under 2+3 years Sony warranty.

Oh, i thought he came to your house and inspected your tv haha. Btw I read some where that in Europe, the latest firmware which is v6.1534 is taken down from their website so there might be a new firmware coming to us soon which I hope can fix this problem.

Btw did u follow the PS5 HDR settings recommended by Vincent Teoh, the 15-15-0 clicks?

It's something that once you seen it cant be unseen haha. I still think its a software bug.
Hmm X90H launched last year and normally Sony TV comes with 2 years warranty right? Warranty ended so fast?
