Soundbar: Philips fidelio b97/10 stopped connecting wireless to Subwoofer

Sun, 12 Jul 2026 08:15:26 -0700

Hi everyone, I bought this soundbar about 2 and a half years ago (lucky me — it broke just as the warranty was ending). I've used it regularly, but not every day, so it definitely hasn't been overused. Everything worked flawlessly until 5 days ago, when it suddenly stopped connecting to the subwoofer and rear speakers (the rear speakers still work when plugged directly into the soundbar).

I've already tried a factory reset, unplugging everything, and re-pairing — nothing worked. I suspect a small component on the board might have failed.

The soundbar can still connect via Wi‑Fi or Bluetooth to my phone, and the app detects it without any issues. But without the subwoofer, it loses half its purpose, and it's a shame to throw away such an expensive piece of gear.

Has anyone experienced the same issue or has any idea what could be causing this? I haven't been able to find a repair center in my city yet.

Thanks in advance for any help!

I have removed the two hidden screws on the bottom and try to use a spudger to remove the faceplate, then a knife, then a flat head screwdriver. I cannot get them separated without severely damaging the shell.

Sony ZS-RS60BT Repair: My device keeps powering off when I play a CD

Tue, 30 Jun 2026 11:40:47 -0700

I thrifted this radio like 6 months. It was in perfect condition and I've only been using it to play my CDs. But until today, when I went to go play my second CD of the day, it randomly just powered off. It can play the CDs perfectly fine, no skipping or anything, but after a few minutes the red light disappears and just powers off for no reason. Idk if I need to replace the batteries because when I bought it, there was already working batteries inside that were brand new so I didn't bother replacing it. I also don't know if it could be the power cord because it's also in good condition and it's been giving me no issues until today.

Logitech Z623 Speaker System: How do I fix a subwoofer that has no sound?

Mon, 22 Jun 2026 21:54:14 -0700

The left/right speakers work, so it has power and is connected properly; no sound (not even a buzz) from the subwoofer. Not sure if it is a macOS configuration issue, or if I need to get in and see what's what. Any assistance you can provide would be appreciated.

Speaker: Why does Pioneer SB23W Sound Bar Shut off 10 Secs with popping sound?

I have a Pioneer SB23W Bluetooth enabled sound bar. The sound bar started making “popping’ sounds 10-20 seconds after turning on then it shuts down as like a circuit breaker. Is there an internal circuit breaker or is this a capacitor issue or something else?

Logitech G560 LIGHTSYNC Gaming Speakers: Logitech G560 volume randomly decreases by itself after firmware updat

Mon, 08 Jun 2026 09:27:42 -0700

My Logitech G560 speakers are working normally. The sound works, the lights work, and all speakers are functioning correctly.

The only issue is that the volume randomly decreases by itself.

The problem started after a firmware update. I tried reinstalling G HUB, reinstalling drivers, testing different connections, and using the speakers on another PC, but the issue remains.

I also took the speakers to an electronics technician, and he believes the fault may be related to an internal component on the main board.

Has anyone experienced this issue before? If so, which component is usually responsible, and is there any way to source or replace the faulty part?

Any help would be greatly appreciated.

LG Speaker: Xboom GO xg7QBK not working

Fri, 29 May 2026 12:54:09 -0700

Hi,

I've updated the post below.

I have a LG Xboom GO XG7QBK that doesn't "work":

After pressing the power button the power led turns on.
- Pressing it again doesn't turn it off.
- No sound output (beeps or whatever on startup, buttons)
- I can hard reset it (7sec power + boost button) after which the devices turns off, but doesn't solve the issue
Can't put in BT Pairing mode
When plugging in the charger, no battery led indications.
- The device turns on with the battery only, charger disconnected.
- The device turns on with charger plugged in, battery disconnected.
- The device turns on with both connected
Pressing the power and volume up/down for two seconds make the power led blink 4 times, to turn on/off "auto power management".
If i connect it to the wall, and then use a cable to connect my phone, it charges the phone.
After opening it up:
- Replaced the cable that connects the buttons to main board (damaged it while disassembling, replaced it just to be sure), no change in behaviour
- When pressing BT + Play/Pause for two seconds, all leds (colours+power+Boost+Bluetooth) start blinking except for the battery leds. Colours stop after 1min or so.
  - When in this state i can't convince the device to hard reset. Need to remove power source to "turn off".

Pictures of the motherboard, no apparent damage, ill review all components when i have a magnifier.

Any suggestions on next steps to diagnose?

Update:

Ive been using the fixbot do diagnose and check some stuff, and came to the following conclusion:

My LG Xboom Go XG7QBK powers on (Power LED is on), but it is "frozen" or "soft-bricked."

There is no audio, the Bluetooth/Reset buttons do not respond, and it won't produce any sound. I have performed deep troubleshooting on the main board (EBR37418701) and found the following:

Main Power (PVDD) at the TAS5822M amp (Pins 6/7) is 7.38V (Normal).
Logic Power (DVDD) at Pin 9 is 3.39V (Normal).
The Reset pin (MRST) on the Bluetooth daughterboard is 3.2V (High/Normal).
**CRITICAL:** The I2C bus (Pins 11 and 12 on the TAS5822M) is sitting at 0V, but shows high resistance to ground (no short).
**CRITICAL:** Pin 29 (PDN) on the amp is at 0V, meaning the MCU is keeping the amp in shutdown mode.

It seems the Bluetooth module/MCU is powered and not in hardware reset, but it is failing to initialize the I2C bus or execute its boot sequence. I have already tried a battery disconnect and holding the power button to drain capacitors. Is there a known "Force Boot" or "Firmware Recovery" key combination or a specific test point to jump to force a firmware reload on this model? Or does this indicate a failure of the MCU/Flash memory on the daughterboard?

Speaker: How to charge Bluetooth speaker with broken port and NO soldering iron?

Tue, 26 May 2026 06:33:19 -0700

I have a generic Bluetooth speaker with a broken charging port and I don't have a soldering iron or the ability to buy any parts or tools. I have a cut USB cable. Where can I safely connect the power wires to this specific red PCB (pictured) to charge the 18650 battery without causing a fire? The port was next to the SD card slot. Also, there is a loose red wire that I think is the antenna.
