No HDMI picture with Tronsmart Vega S89

[mito]

Hi there,
I can't connect my TV with the Vega box with a HDMI-Cable. I did already test different HDMI-Cables an ports at the TV but I get no picture. The only way to see something is using the AV-cable (FBAS). In the settings is HDMI autodetect, but the box does'nt do it. What the hell could this be?
It worked already with Finless 1.4 firmware, but I don't no what happend.
