vizio E470VL HDMI OUTPUT NOT WORKING

[Tekno]

I HAVE A VIZIO E470VL everything seems to be working fine but no HDMI OUTPUT from all ...except from one hdmi port but i get no sound the other hdmi outputs no video or sound

I will be uploading pics tomorrow for you guys to see. NO obvious signs of burnt components on mainboard. none on PSU either.

I am leaning towards the HDMI IC might be faulty...but just needed to know for sure

anyone ever experience this before?
