JBL Speaker: Partybox 200 won't turn on anymore

Tue, 28 Apr 2026 19:30:48 -0700

Hello,

I have had the JBL Partybox for over a year now and suddenly after pretty light use, it just stopped turning on.

The Power light illuminates orange so i know its getting power, I have opened it up and made sure all the ribbon cables and connectors were snug. I also have re-flowed and measured the power switch on the circuit board just to make sure it’s not the switch.

I can’t test any sort of power or connection since I can’t turn it on unfortunately.

I can’t seem to find anyone having the same issues as me so I am hoping I can find some help on here! Thank you in advance.

JBL Speaker: Opened JBL Bar 2.1 and have some interesting findings. Please help

Sat, 07 Mar 2026 23:08:24 -0700

I had asked this question on here a few months ago but that time I hadn't opened it or done anything to trouble shoot.

I have a 2yr old JBL Bar 2.1 Mk2. It stopped working about 2-3 months ago and I've opened it up now to try to see what could be the problem.

When playing any audio from any source, it creates a very loud screech sound from the speakers.

It is only present when audio is being played, it gets louder if volume is increased but if nothing is being played and volume is at 100, no screeching sound is there.

System sounds like bluetooth connected tune also make the same screeching noise.

Today I opened it up, there's a Switch Mode power supply and it connects to the main audio board with one pair of wires. This runs at 23V.

Then at the audio board, there are four big ICs only

ES8680FSB (DAC?)
EP92A2S4 (HDMI Arc)
2x Realtek ALC1322 with heatsinks on both (class d amp and codec?)

I thought there would be some dedicated IC for the class d amp but there's nothing obvious on either side of the board and only those two chips have a heatsink on them.

I've added a pic of the audio board. There's some white goo on the ALC 1322 chips from the heatsink.

The notable SMD parts

8 inductors near output pins (220 µH)
Around this, 5 electrolytic capacitors (220 µF 35V)
Little to the right, 1 inductor marked 100 µH
Near this, 2 x 220µF 16V and one 100µF 35V capacitors
To the edge of the board there's a 220µF 16V capacitor

There's two four pin outputs which are L,R Tweeter +ve, -ve and L,R Speaker +ve, -ve. So total 8 speaker pins.

What all I've measured:

Voltage at the 5 capacitors is 23V
On the capacitors next to the 100µH inductor, it has 5V
Resistance of speaker output + and - is 98kΩ
Resistance of speaker output + and speaker output - both to ground is 48kΩ
No ICs get very hot when I run it
DC voltage across speaker output is 0.002V?

Other very notable thing I also noticed was that when I ran the audio board without connecting the speakers, there was the same screeching sound but much fainter coming from the audio board itself.

Touching or holding the inductors would only barely reduce the volume of the noise.

Connecting the speakers would amplify this same noise 10x as it would be coming from the board and speakers too.

Please guide me on what to do next.

JBL Speaker: Pulse 3 not charging even after battery replacement

Mon, 20 May 2024 09:17:57 -0700

Hello!
Anyone has any idea on how to fix a blinking red light when charinging a JBL Pulse 3.

I have swapped the battery for a new one but it just keeps blinking a red light when the charger is plugged in and won't turn on. There is also a high-pitched sound when it's connected to the charger but that might be a normal electronic whine.

Unfortunately the JBL Spyro is making a loud humming sound that gets me a headache. No one can stand this sound so I cannot use it anymore. I already checked all the cables and everything is right here. How can I get rid of this humming?

JBL Speaker: Why is my JBL GO2 connecting but not playing music correctly?

Sat, 11 Sep 2021 11:42:01 -0700

It is the first time I use my JBL GO2. I didn’t charge it before using it. It connected to my phone and my laptop, working perfectly fine. Then (after an hour of using it) the sound started to be unclear with strong noises. I tried resetting it, turning it off, connecting to other devices,.. nothing is working.

When I turn it on, it makes a weird permanent sound. What can I do?

JBL Speaker: JBL SUB 140/230 Active Subwoofer continuously resets itself

Tue, 10 Aug 2021 06:40:27 -0700

Hi,

I have a problem where the subwoofer (JBL SUB 140/230) resets itself all the time when plugged in. Resets happen every few seconds or so. When plugged in, subwoofer turns on green light and speaker produces continuous static sound. After a second or so, subwoofer blinks red, speaker makes loud boom (short deep sound) noise and it shuts off. And it does that over and over again.

I have tried to play sound to it but it doesn’t change the situation. I have also tried to connect satellite speakers to the subwoofer and it also doesn’t make any difference.

I assume it is some kind of a problem with the electronics inside. I have checked speaker’s resistance and it is good.

What might be the cause of the issue?

JBL Speaker: JBL Go 2 only turning on while on charger.

Wed, 16 Jun 2021 17:19:29 -0700

I bought a JBL Go 2 for Christmas, and it only turns on when I plug it in. There is a blinking white dot. While plugged in it works perfectly, connects to bluetooth and plays music, but as soon as I plug the cable out it turns off and wont turn on. It was on charger for more than a day so I dont think its not charged. Its brand new, bought in december. I tried these things which I found on this page (reset and etc) but it didn't help. Any solutions or should I return it?

JBL Speaker: Why can I not hear music, but other stuff I can?

Wed, 03 Feb 2021 11:27:18 -0700

So, I have a JBL Speaker (I don’t know the exact model) and while I’m in a call, I usually listen to some relaxing music on YouTube with headphones on, but when I tried to do both stuff in my JBL Speaker, I can’t listen to the music, only to the call, and when I open the sound manager, it displays as if a different device was connected and doesn’t give any audio at all.
