Question about JBL PB10 Subwoofer
Hello, I have had the JBL PB10 for several years and have had no problems. I went away on vacation and came home to a loud humming and crackling noise coming from the sub even though my receiver and all other components were powered off. The sound continues when I disconect the input coming from the reciever and does not change upon adjusting any of the dials/switches on the built-in amplifier. I also noticed that the two LED lights on the front are a mixed red and green color. Does this sub possibly have a fuse that needs replacing or is there anything I can do to test for troubleshooting? Please help! Thank you in advance.
If you take all of the screws out of the panel where the inputs are you can get to the fuse. It is just above the power supply.

Hello, Jesse. I doubt I can help, but there is at least one SIMPLE thing you can try - with maybe a 10% chance it wil return your unit to normal: Unplug the unit for 30 seconds, then plug it back in to a DIFFERENT outlet. Oh, yes - there are NO fuses or other "reset" devices. I'm sorry I couldn't offer you more help.
