Hello, my Acer aspire one screen isn't working. I took it apart, unplugged the cable, and plugged it back in securely. Still nothing. I tried taking the battery out and holding the power button, still nothing. I tried connecting it to an external monitor, nothing again. What can I do to fix it? Thanks in advance. Oh, and yes it boots up like normal. It's as if it starts up but the screen gets nothing.
