Hello our hpdvr box is not working and I have unplugged it for 30 sec 3 times tried changing the HDMI but there is only one outlet on the back for the cable we have. when it powers back on it flashes du-1
DUI is HDCPThere will only be one spot on the PVR for the cable, but can you try a different port on your TV? Swap the cable end-for-end, or even swap it with another cable?
Let us know if kevinds's suggestion works or not. We'll look into the problem further if not.
