The HLG teststream, causes a flash of the screen content then BLACK screen and locked up STB HD51.

The HLG test stream can be tried on Astra 19.2 E 10714mghz Horizontal.

BTW when using my LG oled E6V built in tuner the test channel HLG works just fine.

Is there a known problem that will be solved in a later update ????
