Hantek DSO8072E doesn't turn on

Nikolay

Hello,

Something happen with Hantek DSO8072E. It doesn't turn on. When I press power button it beeps and turn on flashlight on the back side. On second press it turns off flash light. Buttons backlight sometimes turns on/off with back flashlight. Screen backlight turns on 1 out of 20 power button press, but there is no picture. Device is not recognisable via USB port.
I have strong feeling that there is something with firmware.

Any suggestions how to diagnose this device? There must be UART on the board somewhere, and technically it possible to read kerenel output on booting... do anybody know where UART is?
Any ideas how to flash it with new firmware?
