P2412H, black screen, fixed

I had a similar problem as this 2017 thread with my P2412H. I took it to my favorite tech team in Nairobi Kenya and this is what we did to fix it; we modified a simple heatsink and fitted it to the LCD panel to help in the cooling of the board. It means the board if functioning well thus, it displays first before it goes dark, but it overheats hence the lcd capacitors automatically disables operation, with an extra cooling mechanism, am still using my monitor to date during Corona Virus 2021.
