We are first time home owners and trying to learn basic things. We mounted our TV ourselves yesterday. I'm now trying to hide the wires. There is already a rugged conduit (something like this) behind the wall to pass the cables to the other end where the switchboard can be seen (bottom right in image)
I took a 6 feet long HDMI cable. First, I tried to put it down from the top of the pipe. The entrance to the pipe can be seen right below the TV.The cable goes in about 4 feet and then gets stuck. After that, I tried same thing from bottom. I pushed the cable up and after about 4-5 feet, it again got stuck. I'm not sure how to get the cable through other end. I tried with another TV cable as well that wasn't as sturdy as HDMI and that got stuck at the same point. Thanks.
Update: I already tried the vacuum approach. I cannot put a vacuum cleaner pipe on either side. On top, the vacuum cleaner pipe wouldn't go because the conduit is vertical and my Vacuum cleaner is a longer end, unable to tilt into that tiny opening of pipe. On the bottom end, there are other wires and insulation and I'm worried that would be damaged by the suction of vacuum..and also same problem of longer vacuum end. This is my vacuum cleaner and the black solid pipe at the end isn't detachable or flexible.
