TBC2 Black screen / no output

I powered on my system today, TBC2 screen was on but there was no output from ESG3 so I switched everything off, checked connections on the HDMI converter / display and switched the system back on. after this the ESG is working and sending out signal to the converter / display but the TBC has a black screen and is not responsive . anyone know how to fix this ? cheers

Sorry for the trouble!
