Wont Turn On?

I’ve left my box on for a week or so, just gone back to it to use it and there is a black screen. Powered off and on, nothing (other than the white light on the front). Tried doing it with the reset button pressed down both when powering on and when powered on… nothing other than the white light…

Is it cooked?

Try connecting it via the composite cable that came with it and see if you get a picture that way.  If so, maybe the HDMI settings just got messed up.

It wasn’t that, but in doing it I used a different HDMI cable and that worked, so thanks for pointing me in the right direction
