Hello @Vestigial Voice - I need help regarding my JBL PB 12 (Revision 1) subwoofer. The sub will just blow the fuse immediately after connected to power. I de-soldered the 2 capacitors (C1 and C2) and checked them. They are rated at 2200 mF and one measures 2190 and other one at 2270. Should I replace the capacitors? What do you think could be the reason for the sub blowing up fuses.

@VestigialVoice

Hi Alok, if you properly tested those capacitors, then I doubt that is the problem. It sounds more like you have a short circuit which is allowing too much current to flow across the fuse, which, in turn, keeps blowing the fuse out. The good news: if it weren't for that fuse blowing out, your hardware would be damaged. As to where it is happening, you'll have to hunt around with that multimeter, good luck, my friend 🍀

It certainly could be, juan. Open up your sub box to take a look at your large capacitors.

I see your videos and also read your very active and helpful in comments. Perhaps you can clear up some questions I have? PB10 = red lights only, no bass or green lights Tried replacing cables, tried “Y” cable, different settings, etc However, when I ran single RCA output straight from BR player to sub input, I got the green lights and the sound worked. So I assumed AVR was culprit. Replace my Yamaha with new Denon and same problem. When I ran the Denon speaker setup test, the sub lights turn green, played the tone and passed the test. I’ve tried every HDMI input device and not a peep, just the red lights. Also tried the Denon LFE+Main option. Nothing. What test signal (tone) comes from the internal AVR circuitry that apparently isn’t received from any HDMI inputs (or my components)? Surely every HDMI cable I own hasn’t gone bad. Do they need to be 2020 models? Lol Is the BR/DVD audio output (bypassing AVR ) to sub input a reliable test to go by? Any help is appreciated. Kind of like new AVR, but still in return window and could get nice sub replacement for that price.

I forgot to mention the Denon AVR has a initial setup tone to test the speakers, and another “white noise” type sound that’s used from a different menu. The PB10 works for the setup tone (chime), but not responding (green light or sound) for the other test noise (soft static sound). I also should have said I’m using all JBL speakers in a 5.1 setup with large CL2 rated 14ga AWG 4-conductor copper speaker wire, and dual shielded RCA sub cable.

Hi Kyle, good analysis (discovering it worked with test tones). I have a couple questions and then a general grievance. --What happens when you plug either of those receivers into a DIFFERENT subwoofer that's been verified to work? --Are you able to get thump in that setup? This test will troubleshoot the problem as with the receivers/settings/cables versus the subwoofer. --Also, if you haven't already tried, make sure to play slightly louder MUSIC when you test. Don't use television broadcasts, especially for this sub. Which leads into my grievance. --Often, my PB10 remains in standby (red lamps), while watching television. When it does finally kick in, it seems to only half-heartedly hit that very first note, before performing regularly again. Caps should take care of that right (lol)? Only in the ideal world... These are the situations we compromise with when using budget equipment. I look forward to hearing from you soon. Thank you for the comment 👌🏼

@@VestigialVoice Thanks for the reply, and yes I’ve noticed as the speakers (or myself) age, it takes more volume to switch them into green light mode. That was before the latest dilemma. I did go out and buy a new Klipsch 12” sub and it works without any problem. Im still haven’t tweaked the sound, and I plan to give the Denon Audyssey setup a shot. It would be nice to have the JBL working as my 2nd sub. So I guess the faulty equipment was/is the sub. When it passed the test (I learned about online) by running RCA’s direct from a optical player, I rushed out and replaced a 2 year old Yamaha AVR with a new Denon. Disappointed it didn’t fix my sub problem and it even caused another small one. Now I really like the new Denon and plan to keep it. So that’s won’t likely go over well. From what I’ve read here, sounds like you would start by replacing the capacitors, correct? I can buy the parts but need to find someone with a steady hand to do the labor. I struggle changing a lightbulb, and I’d be nervous as a whore in church messing with electronics internals. Thank you so much for helping the many people here, sharing your knowledge, without sounding condescending. I hope lots of good karma comes your way.

It is an RS606 AC that handles an 800V max (if memory serves, the original was a 600V, but don't hold me to that). I purchased mine off ebay from a vendor in Europe, but you can probably find an equivalent on digikey or mouser.com. Have a great weekend!! :)

I doubt anyone will see this, but I am having the problem where as soon as I plug it in, the fuse blows. Caps are ok, I was sure the bridge rectifier was shorted, and replaced it, but it turned out that when out of circuit the BR tested ok and not shorted. So now I am out of ideas and hoping it is not the module, although I think I saw a post headline somewhere that someone was able to fix their module. Anyone have any ideas what else could be causing this? I have been testing the board when out of the box, so nothing to do with the speaker. Also tested the transformer and that is ok.

Geez, HM, that noise would bother me ;) From what I can hear, it's making the same sound as a subwoofer being plugged in, which almost leads me to believe, after large bass-hits, the power becomes depleted (or is a weak solder joint to the PSU). Typically, there are multiple (usually 2) large capacitors. I would start there (see my first JBL repair video). With only 1 fully functional cap in circuit, the sub will eventually fail. The good news is: this is a fairly simple fix. Make sure to get the polarity correct (+ and -). Also, I would recommend replacing both capacitors if you find that to be the problem. You will be able to verify the failed capacitor, using a multimeter, after removal from the circuit (unless you have a ESR tester, which allows you to test without removing the capacitor). Let me know what you find out!
