Xbox HDR Stopped working (Flickers and goes entirely blank after some time) with LG 4K...

I've been using my Xbox for 1 1/2 years, and since last few weeks, it started to show symptoms of an HDR issue with my LG 4K Nanocell TV. I had enabled "HDMI Ultra HD Deep Color" on my TV (which enables HDR) since the beginning, and it worked fine. Recently
I started to see random flickers (black screen) when using xbox, and now it has become worse as the screen goes entirely blank after some time and the TV shows "No Signal". When I disable "Ultra HD Deep Color" it works fine. I can confirm that TV is working
fine because I tried Xbox with my HDR-enabled monitor, and I could reproduce the same issue with my monitor too.

I tried:

• Factory resetting Xbox (did 2 times, no luck)
• Factory resetting TV (obviously didn't help)
• Try with another HDMI cable (tried with 3 different cables, the result is the same)
• Try with another Monitor which has HDR capability (similar to my TV, flickers and goes entirely blank after some time)
• Disable HDR on TV (works fine when disabled HDR on TV)
• Disable HDR on Xbox (didn't help)
• Change resolution to 1080p (didn't help)
• Change bit depth to 8bit (I played with 10bit since the beginning, changing to 8 bit didn't work either)
• Enable "Allow YCC 4:2:2" on xbox (didn't help)

I found this thread (https://answers.microsoft.com/en-us...ox-one-x/7a19fb8e-5e06-4072-b398-9be56754cf69) which
explains the exact issue. But in my case, I don't need to disable HDR as a workaround. Lucky for me I have 2 years of warranty and I thought of sending it for repair/replacement.

Internet is filled with similar issues related to Xbox HDR, but none of them solved my issue. This is almost making myself ditch Xbox and switch to PS5.

Is anyone else experiencing the same issue?
