I have a problem with my re190. It was working fine before. Suddenly it was not working and when checking the device, no LEDs were on or blinking at all.

After removing it from the power outlet and plugging it back in:

all LEDs light up for a second (including a red one)

the power LED blinks 3 times

power LED turns on for a few seconds

power LED blinks 15 times

After this all LEDs turn off and nothing happens anymore. I'm not able to connect to the device and it is not responding in any way to pressing the reset button.

What else can I do?
