I can't say this for sure but it's either the power supply or whatever it's plugged into that causes the problem.

If it is indeed a power supply problem then I don't recommend you mess with it unless you have a fare bit of background in electronic repairs.
Take it to the shop. Posting at Synth forums isn't going to fix it.
