Yes. It is probably a bum resistor. I have repaire two on mine. There are two resistors, the one closer to the end where you plug in the powerheads is the one that usually goes first. Just clip it off, go to radioshack, buy a pack of 4 for under $2 and re solder it on. Really simple. If that doesn't work then you can replace the other one in line, b ut usually the first one is the one that is out. Good luck.....some where the is a thread on it but I do not think it is on rc. try a google search.
