I have an acer AL1916w monitor. It was working fine earlier today. I went to use the computer and the monitor was not on. The power light goes from green to amber then off. I have tried unplugging it, and nothing happens. I know the video card in the PC is fine because an older monitor works. I have also tried to connect the monitor to my laptop. It gets recognized, but still won't power on and has the same flashing lights. Could someone please help with this? I'd hate to have to junk it.
