Sony 65X90J, 3 years 9 months ... (note: replace panel after close to 2 years, and replace power board ~6 months later)

In the middle of a watch, the screen is quickly fade to black only sound remaining. Power cycle it doesn't work. The TV can only produce sounds and respond to remove. I tried to see if I can see any image, but using the brightest light on my phone still does not show anything. I put a gentle knock on the screen and can see a burst of light.

My thought
* It's NOT main board: can power on and reach dashboard, response to remote when I change to TV
* It's NOT backlight: ??? since I can't see any display at all. How to confirm this? probably need to open it up, right?

Can it be t-con board only?

@limtk55 - do you provide service?
If not, anyone can recommend repair service?

Looks like no hope. TV panel is gone. Repair with Sony would be ~900 and with only 3 months warranty. Considering both panels failed in less than 2 years, 3 months warranty seems extremely risky.
