I bought a flat cable on monoprice to run through my wall a few months ago.
I was having some trouble with my AVR (which I thought was handshaking) but when I connected straight from cable box to TV I find I have the same issue. The screen turns black or doesn't show signal. unplugging and replugging the cable fixes it, but its such a hassle to have to get up and mess with cords when it worked fine when i powered the devices down.
So i'm wondering..
since i have a tv that isn't up to 1.4 standards and a cable that is, could that cause the issue? would a software update on the tv fix it?
or is it likely an issue with the cable itself?
