My 301 just locked up during operation, it was processing signals and sampling etc but I wasn’t controlling the unit via the interface at the time.
I switched off the case and then switched it back on but the 301 did not power up. I removed the screws to take a look behind the module and check everything was wired correctly.
The green and red lights on the cpu board are on but no leds etc on the front or screens are active when powered.
In fact the 301 wasn’t doing anything, I’d been playing with some other modules and then looked over at it and the screen had crashed out again, similar to the picture above. Looks like it has got a fault.
That doesn’t look like a firmware problem. It looks suspiciously like a power problem. Also, the turning it off for awhile and having it work again when you turn it back on points to that too. Can you post your case power info please?
