Bad power board or bad backlight array? Flashlight visible logo
The 4K TV is my PC monitor. Model is 43PUH6101/88
Yesterday, I was working on my PC and noticed the screen went dimmer and dimmer.
More on the top of the screen than on the bottom at first.
And within 4 seconds the screen was totally black while the sound was working.
I took pictures with a flashlight of Philips (quality) logo and HDMI message:
Does the dimming light happening in 4s could point if it’s the array or the power board?
Do you know resources to open it and test it?
Thank you very much!
