BuzzTV XRS 4500 not booting

box was working ok but now it wont boot, just keeps turning itself on and off. order the box in april 2020 from WorldWideSatellites so i think it still under warranty. just wondering if anyone has come across same issue, any help or suggestions is greatly appreciated, thanks in advance.

HDMI cables can sometimes cause the rebooting.
If you have another cable try that, or if not unplug the HDMI and try a start up and watch the lights on the box to see if it is rebooting of if it is stable.

You can always try a pin reset too
