JBL esc333 sub not working

Hi, since my 3 yr old dropped a toy into the port and I removed it by taking the back off the sub no longer works. I noticed a couple of broken capacitors which I replaced but the problem is still there. as I live in the UK, can someone advise me of the best course of action. The system sounds great and am reluctant to bin it yet (cost of fixing it to buying another).
Thanks Ilyas

Well, I have recently inherited one from a family member, but this one came with the same issue. I simply drilled a small hole into the metal grating, completely bypassing the circuit boards inside. I reconnected a piece of fresh speaker wire to the sub, and had that plugged into my receiver. Now, not only can I boost my sub, I can also control its volume.(It didn't come with the remote either!)

My esc333 packed up soon after I bought it (2nd hand on ebay). No original speaker connectors came with mine so I had to hack into said connectors and solder some cables straight onto the PCB, all was OK for a couple of days then no joy, although it appeared to power up.

After a while I decided to strip the whole thing apart. I simply undid every connection and put it back together again (I'd suspected a dodgy connection). After this back in business.

My only gripe is that I received no external infrared receiver with mine. So some of the advanced adjustments, which you can only make with the remote I can't do. If you are thinking of scrapping yours I'd be interested in buying that off you?

Sounds like you've blown them.

When you were playing back to the friend, were you playing louder than usual?

Was the old box ported, and the new one sealed? The lack of ventilation may have caused the blow...

How do you disassembly the JBL PSW_D110?


what i did was i stuck my hand in the port, screw driver in hand, used the blunt end of the screwdriver put it in the indent on the magnet on the back of the sub, positioned it so that the end of the screw driver was stickin out and smacked it with a hammer and it popped out, make sure u take the screws out of the front of the sub, and then take the insulation out of the box and do the same thing to th eboard just do it on theblack part of the amp not on the board

JBL spot series speaker not working.


I know this is old but just incase anyone has the same problem. Its proabably the connection from back panel to the internal amp (Inside the sub enclosure). The ribbon cable has the + for the left speaker right at the edge with quite a bit of tension. Over time and with the vibrations from the sub this will bend/pull out slightly and needs to be pushed back on and some hot glue put around the connection to hold it in place.

Thats how I fixed mine anyway.
