Question about JBL Northridge E 250P Subwoofer
Light stays red does not change to green when recieving signal.sub doesn't come on.
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.

I had the same problem...replaced the C42 capacitor with one that I got from RS...fixed everything and all is well again. I only have moderate soldering skills, too, so if I can do it, so can you

More likely to be the Class D power amp module, but you should look through the service manual to make sure all the parts are installed correctly. My PB10 AMP module went out and you cannot get one anymore.
