In the USA many products get another 3 months when you register it. QUICK. DO THAT.
As to he protect message, I've lost count how many times it was a short in the wires.
I have a Samsung HW-C500 Home theatre Amp and it keeps shutting down with the ( Protection ) flashing then shuts itself off. I am using the proper gauge spkr wires ,trimmed, attached properly.Spkrs r good also ? Any one out there with a way to disable or repair this annoyance? As Always 3 months after warranty is over.
