Sorry your display is damaged. I’m suspecting you tend to use a spray cleaner on the screen give it a couple of deep sprays getting nice and wet! Letting the cleaner drip down. Sadly thats what did you in! The liquid got to the bottom edge into the circuity located there damaging it.
Please don’t spray the screen instead spray the clean micro cloth and use it to wipe the screen.
You might be able to fix your system but its a bit tricky! You’ll need to carefully lift the bezel around the screen to get tn the LVDS connector at the bottom of it to clean the build up of dried cleaner and the corrosion. You may need to replace the LVDS cable if its damaged. Otherwise you’ll need a new display assembly [product|IF188-096-5] and here’s the guide to do it [guide|40753]
