Hello,

My Startsat 2000 HD Hyper, the panel show `BOOT` and after a few seconds it goes to ON and a few seconds later top right on `ON` SATTV word will appear.

I don't have screen with HDMI and black Screen with Yellow video cable.
Noting changed on panel when I press remote control buttons or devices buttons

What should I do?
