I have an ongoing problem with the HDMI output of my VIP722. The component output always works, but not the HDMI output. If I umplug the cable and reinsert it, the TV receives the signal. I have tried another cable, and it does not solve the problem. The HDMI output is like snow, and flashing. If the cable is removed, the TV message is no usable signal. Anyone have any other suggestions. This is annoying, and my wife is getting very impatient about this problem.
