@MarkHaysHarris777, what red light are you talking about???
Today i also realised that my HDMI Monitor gets disturbed if the Pine get stuck whilst booting.
I even can't get in the service menu of the monitor until i pull out the HDMI cable.![Huh Huh](https://forum.pine64.org/images/smilies/huh.png)
Maybe there is a communication problem between monitor and pine at boot stage,
and if the monitor is absent the pine didn't recognise that and this communication problem seems to increase drastically.
Only my thougt after much testing on that.....
