The junction cable problem

I bought DM6 elec. drum kit two years ago.
It's in Chennai.
Recently some sound problem happened and I asked the dealer to check what problem happend. He told it's junction cable problem and it should be replaced.
So I asked him to replace it but he told it was not possible because the cable was not available.
Actually I am not sure it is a junction cable problem.
How can I get your technical support?
I really hope you could help me.
I will be looking forward to receiving your quick and kind reply.
