Monitor Samsung FP460-3

[Erika Tinoco]

I have a Samsung monitor, model 460FP-3. It has been working properly by HDMI but I plugged a device by VGA, then I went back to HDMI source and it didn't work. Now the monitor seems to be blocked in some way that I can't run it by HDMI. Could you help me? I've tried resetting to factory settings.
