@felek I'm in uk. I have equipment for it. And dont have warranty

I just found a post where guy had shor circuit on a board and it looks exactly like mine with almost all leds lit, and he's cpu was damaged, but I haven't open a compartment with pcb, and didn't charge anything. Any idea if it is possible that it only could is damaged or something more could be damaged, or how it could happen without touching anything.

@felek
No. Printer works almost a year.
No issues and no modifications has been made since I've started using it. Just stopped working.

@felek Unfortunately nothing changed.

@felek
Cable that I'm using is detecting Panel Due without any problems and other devices as well.
I have removed whole board from printer and tried to connect it to pc with no success to detect it,
So I have started erase procedure described on duet website.
Put erase connector on pins,
Plug in to USB and wait few seconds
Unplug and remove erase connector
Plug it in again.
Tried that many times without success.
Is your method should be made while board is plugged in to USB all the time or disconnect it at some point ??

Hi all.
I need you help if possible.
My printer works fine for around a year. Yesterday I've started another print after one was done and printer just freeze. Panel due didn't respond for any commands. Board doesn't start after restart it, WiFi led is off all the time. 5V and 3.3V led is on, diag led is constantly lit. I tried connect it to pc but my pc is not detecting it, so I tried with other 2 pc's and same problem, so I can't even upgrade firmware, I also tried to use erase pins tens of times without success, reset button also not changing anything. Here is a video.
I have tried also change sd card, and tried to turn it on with or without sd card nothing changed.
