Question about Audio & Video Receivers

My JBL PD12 subwoofer stopped working and I opened it and it looked like the fuse was blown so I got a replacement fuse and installed it. As soon as I powered the it on the fuse blew again. Do I need to replace something else or is it just garbage at this point?

Check the cable between your sub and the receiver for short circuit and if the cable is ok you will have an problem in the printed board.

My Boston Acustic subwoofer connected to my Denon Avr 1312 is not turning on the les light on back of subwoofer dobt even come on had fuse checked but its not blown.


There is a common problem with a zener diode in that amp that goes bad. ZD3 is a 18v zener and it goes short. Sometimes R9 on the back will open when this happens. Need to have them replaced.

I have an additional subwoofer 10" JBL. How do I go about hooking it up with my sony receiver GX800ES?


That is a capable unit. Do you have a user manual? If not, it is here:
http://esupport.sony.com/US/perl/model-home.pl?mdl=STRGX800ES&template_id=1&region_id=1&tab=manuals#/manualsTab
In there it says you connect the subwoofer to the "Surround Out - Mono" output terminal.

I bought a Denon AVR-2807 used from eBay, I got it hooked up properly to my speakers, JBL E100 front bi-amped, JBL EC35 center and E50 rears, no subwoofer. HDMI from PS3 to Denon and HDMI from Denon to...


TMI.

This is strictly a remote control failure.

Read this procedure to possibly fix the remote:
http://remotes.com/remotes/servlet/rs?a=Display&contents=help_deadremote&uuid=A12963989782821
They also sell replacement remotes.
Or look on eBay, usually much cheaper if available.

Another thing would be to make sure the receiver's remote eye isn't picking up infrared from anything else in the environment.

My Sony receiver is an STR-DE675. The subwoofer stopped working after I moved the receiver, disconnected the cable and reconnected the cable a few times. I have changed the cable and used a different...


I didn't look up the schematic for this exact model, but many of these units have the surround amps on "cards" just like a computer has a video card or network card, and these can come unseated in a move. Open up the unit, and reseat any cards that are in the unit.
You can check fuses while you're inside the unit as well.

Have Acoustimass 15 system. Subwoofer stopped working and I don't think the fuse is blown. Anyway it does not look blown.


OK - well "look" blown may not be a solid, engineering approved, check. You could take the fuse down to a local Radio Shack and have them test it. Good news is that they will probably have a replacement if you need it. OTHERWISE... Keeping the volume WAY down - you can try another speaker on that output. It doesn't really have to be a woofer, just something to verify the circuit is working. That should tell you if the pathway is good which then tells you if its the woofer or the amp/receiver.

Subwoofer stops working after about an hour's use. Authorized repair technician could find nothing wrong.


In case of a transistor which is faulty, could short the power supply in circuitry, and this happens after the transistor gets heated up. So you might wanna inspect the transistors on board to replace if found faulty.

I have a set of JBL JRX125 (s) and the high end won't work on them. Not sure if I blew a fuse or the cone or what. The only audio I can get to come through them is low end.


Hi hoit

They will have either blown high frequency compression driver, or the lamp mounted to the crossover board has failed. Best way to check is pull the horn flare out of the speaker box, and check the voice coil of the HF driver(JBL2412). I think they are 8 ohms from memory. If they are shorted, or more likely open circuit then this is you problem. If they appear ok, then check the lamps. The lamps are there to protect the horns from being overdriven, odd lucks means I have seen it work the other way.
If the JBL part is too pricey for you (they are for me), you can get aftermarket replacements from many places for about $40 each. It is a replacement diaphragm that you need for each HF driver.

You have the subwoofer plugged into ac and you see a light? parhaps the RCA cord is bad. Try another one.

Look for shorted output transistors or possibly shorted rectifier diodes. An immediate fuse blowing up usually means that the power supply is the problem. Keep us posted.
