Your 2A 250v slow-blow fuse is blown, located under the back pannel. Mine just did the same thing. Problem is the problem with my PSW10 goes beyond the fuse. I have contacted Polk tech support to help me trouble shoot.

You will have to remove the plate amp and look on the pcb, it is generally located near where the main power lines come in.

Have you tried using the reset jumper on the motherboard? I had a PC a few months ago that I had to replace the battery in. I eventually had to use the clear CMOS jumper and the reset BIOS jumper to get the computer to load to BIOS normally. Remember, if you don't have to correct the date and time, then the BIOS has not been reset. Sometimes it is a good idea to leave the PC off and unplugged for about 10-15 minutes to let the capacitors drain down. By doing this after reseting the PC, it gives you a clean cold boot (meaning there is nothing stored and nothing has had power before a reboot).
I hd this same problem a couple of months ago. Disconttect all peripherals (any exterior amps, roommates) plug the power connector and wait for two minutes, while waiting connect the main system. try turning the LS 48 on. If this clears thing turn off the LS 48 and connect the peripheral one at a time testing with each new connection. Happy hunting.
Hi Im a Certified Repair technician, I seen few problems with this unit, there is a amplifier module inside this unit, is really hard to find since JBL discontinued this almost immediately.
Sorry no really worth to bother........
If the unit is only a few months old, returnit for warranty repair or exchange. A power fail should not effect it. Try unplugging it for a few hours to force a system reset. If that fails to resolve the problem, have it serviced under warranty.
