Zgemma H9.2S flickering on black screen

Hi!
I have a H9.2S with OpenATV 6.4 installed, and in the last few days I have been experiencing an odd flicker when the screen is completely black. This happens whether I'm watching a film or a TV program. Whenever the the screen is all black, it starts flashing irregularly, with several degrees of "black brightness" (so to speak...) until something appears on it. This doesn't happen if there is anything at all on the image, however dark.
I have checked with other TV sources, and it's most definitely happening only on the ZGemma - I had the doubt that the TV's "Adaptive Brightness" was switched on, but it isn't.
Any ideas?

Thanks!

First thing i would be checking is tv settings were switching from a different mode and what setting is your box set to for hdmi and is tv 4K.
Good quality hdmi cable in use.Dont plug/unplug stuff with units powered on.
