The homerun end of the cable is finicky to the touch and I'm fairly confident that there is an issue with something coming loose in the head or something else "breaking" within the wire / head. This HDMI run is the one used for the output of his receiver in the homerun to the TV a floor up. Additional connections between the two points are two runs of speaker wire, one RG6, a 3.5mm audio cable with an RCA connector on each end, and one Cat5e. Speaker wire is in use handling stereo sound from the receiver. I need to fix the HDMI cable or find him another solution.
My crazy ideas: I've read quite a bit about fixing HDMI cables with wire crimps, soldering, etc and stumbled across a screw terminal HDMI connector like this
leaving you with a female HDMI port. One of them says it won't go higher than 720p and the other doesn't specify. Another idea I had was to connect in proper order to RJ45 heads on each end (two pair if more than 16 wires) and use HDMI extension baluns to send the HDMI through this faked Cat5 cable. I'm confident that won't work, but does anyone know if it will or won't? My last resort would be using a wireless HDMI pair I saw on monoprice but I really want to avoid using wireless to solve the problem.
Ideas, advice, cautions?
First of all, there is no such thing as a 1.3 HDMI cable or a 1.4 HDMI cable. The only two types are High Speed and Standard Speed. If you would like to know more, I can refer to you some threads but basically try not to use a version number with a cable.
Since it is 50 feet, we can be sure it is a standard speed cable since passive high speed cables max out at just over 25 feet.
With that out of the way, trying to repair an HDMI usually ends up with a bad signal (or sometimes) source voltage ending up on the wrong lines. These cables are extremely difficult to repair properly.
So, I have two ideas -
1) Do you have the ability to pull this cable (conduit?) if you could replace it was something more flexible? If so, this is a good use of a Redmere cable.
2) Would a small pigtail at the home run end reduce the stress on the HDMI connector? Basically, it sounds like if that suspect connector is never touched again, it will be OK. So, how much extra cable would that take. Is the cable being used at 1080p (or only 1080i/720p)?
What Joe mentioned would use the cat 5e cable instead of the HDMI cable. The HDMI cable would be abandoned in place.
