Hi Team, I turned on my set top box this evening and initially there was just some shaky sound with no picture and then the sound died all together and I just had a blank screen. Tried power cycling the STB and replacing the HDMI cable to check it wasnt that. Any ideas on how to fix this? The STB powers up with the clear light to show it's on but no picture or sound. The TV doesnt even get a signal from the box.
