I have a quad cortex thatvwill no longer start/boot
When powering up, the foot switches flash five times and then nothing. The screen stays blank.
Every 15 seconds there will be a very brief flash on the screen like it is trying to do something .
I have tried to restart multiple time with always the same result.
I have not recently tried to update firmware etc

Hi, thanks for the response. I did try that yesterday but unfortunately the screen is not displaying anything so cannot use that solution.
Tried again this morning and cortex booted up as normal. I restarted and it is back to the same where lights flash 5 times and screen does nothing.

have you tried booting up with nothing else connected- only the power supply?
Thanks, yes only got the power supply connected and nothing else. Also tried moving to other sockets but same response.
Are you unplugging everything and using the OEM power supply? If not OEM, ensure the PS is providing 12v @ at least 2A (preferably 3A). Lastly, try the factory reset if possible and email
I am using factory power supply. Unfortunately I cannot do factory reset as screen is not displaying anything.
I have emailed support but also posted here to see if anybody has had similar issue.
As stated earlier, it did boot up once this morning before going back to non response.
Just to provide an update, I managed to get the unit to boot up after hours of trying.
I immediately updated the firmware to the latest version and for now that appears to have fixed it.
Spoke to soon - back to same problem. So frustrating.
my unit did this this weekend, i shrugged it off and re-powered it and it came up fine.
now you have me scared af

So it was working again and booted up but now in the same previous state? What occurred from the time you resolved the boot issue to current?

Nothing happened apart from turning it off and starting it up again and it went back to a non- responsive state.
I managed to get it working again late last night and appeared to start working this morning.
At the moment I am not overly confident that it will start

Understood, something is definitely amiss, please email support so that they can log the issue and provide resolution etc.

I have messaged support and it has been agreed that I will monitor the situation but if not it will need to go in for a look.

Just be careful of potentially voiding your warranty. It’s always best to email support so that they can log the issue and provide resolution.
yes, I sent it, if the problem persisted, I would send the QC to them, but I’m in Brazil, it´s very hard send the QC.
We still don’t have support here.

Just to provide an update. The Quad Cortex has been working fine the last 2 to 3 days without a repeat of the problem.
I wish I could say what I did to fix it but honestly I do not know. I think it was more a software problem rather than hardware.
At the moment, I am a bit - is it going to turn on this time?
