Question about JBL PB12 Subwoofer
My subwoofer lights flicker on the front green/red/green. Also a clicking sound. It smelled like an electrical burn of some sort. no power surge. I took out the board and their is a black burn spot on the board. Can it be repaired? Thank you, Daryl
The amps do have issues that is for sure - That is where I step in - I can repair your amp and make it so it won't burn up (catch on fire) again. When the amp goes it burns a hole in the board - but it can be repaired. I have done several hundred and all customers are happy :) ... Look for my add here and also on ebay

These subs have had many problems, all associated with the amplifier section. PB 12's with an "M" as part of the ser. no. were assembled in Mexico and these are the ones with the amp problems. JBL fixed mine and sent it back no charge, BUT it cost me nearly $100 to send it to them in the first place. I have another one that has had no problems at all. Try sending it back for repair. At best you'll get a rebuilt unit back, at worst a substantial discount from the company for a new sub.

if your serial number starts with ha then it's probably a bad capacitor C72 . 6.8uf 100v np electrolytic. replace it with a higher voltage capacitor of the same value.
