Is your subwoofer amplified or passive?
You clearly understand that you need to use a variable line out to control the subwoofer volume via the TV. As the setup seems reasonable, I'm wondering if the subwoofer is getting a signal, but that it is at line-level and not internally amplified by the subwoofer speaker. Generally, if the subwoofer must be plugged into an AC socket in the wall, it has an internal amplifier and can be fed line-level audio. If it is "passive", it has no amplifier, and it must receive an amplified signal (over speaker wire) from an amplifier (or integrated receiver). TV's don't generally have connections to send out an amplified signal.
If the subwoofer is indeed amplified, then this is obviously not the problem, but it's the first thing to verify given the information provided.

that subwoofer has dual 4ohm voice coils, if your amp can handle 2 ohms, you would put a wire from the positive (+) on the amp to the positive on both connectors on the sub, then hook the negative (-) on the amp to the negative on both the sub connectors that will be a 2 ohm load on your amp make sure your amp at 2 ohms is not more than 600 watts RMS or 1200 max.

"Is there any way to repair voice coil?"
the simple answer is no.
the long answer is you could try contacting the mfg of the sub and see if you can order a new foam ring, cone and voice coil to replace the one you will have to destroy to take it out.
