Problem with HDMI over Cat5e

    I have a TV in the kitchen with a SkyQ (main box) in the living room about 15m away. I wanted to split the signal from the SkyQ and run it to the kitchen TV so as I could get a HD signal. I was recommended HDMI over Cat5 on here and duly purchased the required equipment. Installed it and it worked no problem for about 4 years.

    I started having problems recently with the signal dropping. I checked the cable running outside the house and found that part of it had been chewed thanks to our 5 month old German Shepherd :D.

    It was a bit of a pain in the ar$e, as he chewed it right up at the hole in the wall so there wasn't room to get the crimper on to insert a new piece of wire. I was able to remove the skirting inside and run a new piece of wire outside and crimp and then connected in the new pieces of wire with Cat5 female connectors.

    I also have a cable tester so tested in various sections of the wire to ensure my connections were good. All was good.

    However, when I turned on the Sky box, I could get nothing on the kitchen TV. I checked the wiring again and all was fine. I then got a spare mini SkyQ Box and connected it up at the various points that I had crimped. It worked no problem and even worked behind the TV in the living room. Odd.

    There is a splitter at the TV at the living room and connected the Sky Box directly into the HDMI Cat5 converter, I still got nothing. If I put the mini Sky Box into the splitter as with the main Sky Box it worked fine. I reset the main Sky Box and still got nothing. It was giving a perfect HDMI signal via the splitter to the TV in the living room but wouldn't go via the Cat5 to the kitchen TV.

    Am I missing something here? It's odd the one HDMI source worked fine and the other wont. I'm not aware of any HDMI settings on the Sky box that could be affecting this it was working fine before the wire was damance and nothing bar the new connections has changed.

    TIA.

    Can you check the full length of the ethernet cable?

    Tester parts at either end of the full run.

    Just run a new cable end to end. Joining cat5e is always going to be problematic. The number 5 in cat5 is the twists per inch which makes a difference when unwound unevenly

    Yes, tested the full length and at the joins and everything checks out.

    I would if I could, but unfortunately part of it is plastered into the wall for a wall mounted TV. Yes, I've read since that joins in Cat5 are hit and miss for HDMI converters.

    I'll try and switch both cables around on the converters and see if that helps. It may be one cable that's causing the problem rather than both.

    However, still working away 100% on the Sky mini box.
