I have seen where screws have gotten dropped from the upper half of the machine have ended up in back of the PSU board. No visible damage until you pull the board.Originally Posted by KeviM
+1 there is always one tricky screw to get out.
A lazy tech won't chase it when it drops and that is just problems cascading from then on.

I don't think this is the cause, the machine hasn't been touched for technical work since late July/early August, has since done approx. 50,000 prints and is in a very controlled environment with regards to who uses it.
The problem does seem to be power related, I will do an entire control box swap to see if any of the boards on it are to blame.
Is there any point to try doing firmware upgrade on it?
I would try firmware.
But being an end user you haven't seen what we have.
Hell I had one of my lazy techs leave screws partially screwed in. A few LOOSE screws not installed but laying on top of the board cage then installed the covers and walked away. I week later I had to go out on the unit an low and behold, the screws moved due to vibration and fell into the PSU and fried it.
31 years in the industry and I've seen some crazy shit.
Hell had a mouse fry the PSU because he chewed through the cables. He was smoked but still had a wire in his mouth.

Until you can get it to power on consistently, I would not risk it.
The machine is stable as in no LCD/activity LED blinking, it will wait for the handshake timeout between the op panel and the control board and then display the SC-672 but is there any way corrupt firmware could cause flickering/putting the device in some sort of a boot loop, when moments later it booted up just fine, then degraded to constantly trying to turn on and retrying over and over again and then dying again?
Simple answer YES. It can cause freezing... reboots.
But as Slim said you need to find out WHY it's kicking the error AFTER you get it stabilized.

Seeing the video of the display flashing I would like to get a tip out of my head, check the main switch, if burned it can cause false contact.

I'm not sure if the machine will update the firmware if it doesn't get off to a good start first
