I've got two m7200, one is V3 and another one is V2.

The V2 model suddenly stopped working.

Now all 3 LED lights are simultaneosly and permanently on, regardles if the cable is connected or not. At some longer interval is only all shorlty blink and remain lighting on. This is different than before when the LED light would appear one by one, until fully powered off and then it would all disapear after some time. But now all is just on immediately and remains on all the time.

When on the cable it's impossible to turn it off by long press the power button (the lights would go off for a few seconds but came back again sortly after).

When not on the cable it's possible to turn it off. But when turned on again all 3 lights would light up again in the same time and remain on.

Regardless if it's on or off I don't find any Wi-Fi network from it.

It's impossible to reset it by pressing the reset button a few seconds, just nothing happens (unlike before when it worked).

Do you have any suggestion what can I do?

Thank you!
