My friends have a brand new CS 40 AV. They don't speak English so they asked me to write about the problem they had come across.
The initial startup was ok, everything loaded and they started an empty show.
With the console working they inserted a freshly fat32 formatted clean usb stick with a show file written by me in an offline editor.
Just after they plugged the stick in the console switched off completely.
They switched the power off, switched it on and the console started an infinite shut-off/switch-on cycle (freezing on starting up for 1-2 minutes, shutting down than switching on again).
After trying to recover the console according to the official "Creating a ColorSource/ColorSource AV USB Recovery Boot Stick- Internal" instruction, it did accept the latest firmware upload (both from internal drive and from usb stick).
But it does not help and it freezes on starting up for 1-2 minutes, shutting down than switching on again, just like before any recovery attempts.
The test utility from the usb stick shows this:
Can you confirm that the infinite shut-off/switch-on cycle continues without a thumbdrive being plugged in at all?
I think you have tried most of the steps covered in this Support Article: https://support.etcconnect.com/ETC/Consoles/ColorSource/Software_and_Programming/ColorSource_Console_is_Stuck_in_a_Boot_Loopbut make sure you've also tried "Erase All Show Data" (if this works, they'll need to reload the file you provided).
If none of that works, and if the console cycle continues without a thumbdrive plugged in, they will need to get this console looked at by ETC or an Authorized ETC Dealer.

Thank you so much, Matt!
I'm not sure they tried "Erase All Show Data". I'll ask them to try what you advised me to do and write back here in no time.
Guys tried to revive the console the way you advised to - no success. The console cycle continues either with or without a thumbdrive plugged in. Think we need a doctor here.
Many thanks anyway!
As it didn't recover itself, the "Main Board Not Found" in the test mode indicates a hardware failure of either the connection to the facepanel or the facepanel processor itself (also known as coprocessor).
It'll need repairing, please contact the nearest ETC authorized service center and we'll get it sorted out.
