Acer Nitro 5An515 issues

Recently I’ve been having troubles with my Acer Nitro. Initially the problem was the keyboard was flashing on and off every five seconds without the screen turning on. I found a website that recommended taking out a stick of ram and starting it back up. I did this and it started back up and the charger even made a noise, no keyboard flashing, but the screen still isn’t turning on. I tried plugging it into a monitor to see if the screen was broken but it’s not turning on on there too. Any assistance?
