The amount of cables for this television and its components is pretty ridiculous! Though the table top has a hole in the back to allow cable to pass through to the plug underneath (pic 3), it doesn't help the cables that are connecting the components together.
There are a number of products out there to contain and to minimize the look of the cables but I generally try to avoid having to buy any of them. Hiding them behind something usually works just fine.
Here I cut a hole in the back of a black cardboard box (the client already had it, I think a fancy candle came in it) and placed it under the component on the right to tuck the remaining cables in (pic 4 + 5). Most people, including her husband, didn't notice the box until we pointed it out.
Last, I pushed the components as far back to the wall as possible to keep the cables in place and with the television mounted as it is, the cables are really not too visible as you're standing in front of the table (pic 1). Now, if this client wasn't happy with this, I would push it to the next level and maybe make some kind of cover to rest atop of the back of the components to completely hide them. Most likely using a piece of colored cardboard.
