I have an issue, When I had my house built I had the builder run a hdmi and two cat 6 cables to above the fireplace from where my receiver is. I recently was messing with the tv and broke the hdmi end off. I bought one of those cat5 to hdmi converters and have it working, but only if I plug the source directly into it. If I run through a switch then it won't work. Any suggestions and is it possible to put a new hdmi end on? There is no way to run new cables either.
