Can anyone help as to why its doing this?.

When i boot the box up, it shows this image for a couple seconds: https://i.imgur.com/x1qkl5W.jpg

Then it goes blank (no signal).

The box does appear to boot up as the LCD display says so. I can access it via FTP and I can access webilf, albeit i cannot view any channels (Doesn't work).

I have changed HDMI ports and HDMI cable with no success.

Could my HDMI port be faulty or other chips? anyone seen it before?.
