Hi johnny Vette
One of the power boards in the set has given out, the problem is that the boards can be pricey to replace. You have to contact the company to see if any boards are available for your set, then have it replaced by a qualified service technician.
Note: If your set died before the warranty expiration date and if it was purchased at costco or walmart, bring back the set and ask for refund.
