So I have a Toshiba Satellite laptop that I spilled juice on. I opened it up, let it dry and then clean the motherboard with alcohol. Then, after I put it back together, I pressed the power button, the lights turned on as normal but the screen stayed black. I tried connecting a second monitor to it but it didn't work. I haven't pressed any keys to turn on screen mirroring because the keyboard wasn't connected and I think it was broken. I tried removing the RAM and putting it back but after that, when I press the power button all the lights flash once and then they stay off. What should I do?
