Recently my acer Nitro 5 AN515-55-53E5 has had screen flickering. I sent it in to the Acer warehouse and they said it was due to liquid damage. I got it back and cleaned the motherboard with IPA, and it worked for a day, and then it started to glitch again. Are there any other parts that could cause the screen flickering?
@kqsmos that looks like you shortened part of the LCD driver board. That is a board that connects directly to the LCD panel via some very thin ribbons. Take a look at that board and check for corrosion as well as burned/missing components. Be careful, those ribbons are delicate. It might help if you post some good pictures of those boards as well. Update (06/08/2022) @kqsmos no worries about what you consider lack of knowledge. That is okay and that is why you are here. If you would know this, you would not have to be here :-). We need to see what you have going on. You will have to take it apart and post plenty of good pictures so we can evaluate for corrosion. To work on your Nitro 5 use something like this video. You need to start checking on the display adapter for corrosion. How did you clean the board? Did you clean the ribbon cable to the LCD? To replace the LCD you would follow something like this video, but let us help you to evaluate the motherboard display adapter etc.
It seems that I have shorted a part of the LCD driver board, but not the entire thing. Since only a part of it is shorted, it just means that I cannot run my laptop on 144Hz anymore, I changed my Hertz to 60 and it works now. The only downfall is that I get splitting lines when I play games sometimes.
