Sennheiser Momentum 4: Weird sound coming from right ear cup

Fri, 24 Jul 2026 05:46:32 -0700

I've suddenly been dealing with a very loud and startling sound coming from the right ear cup. It's a bit hard to describe but it sounds kind of like a crack, and occurs intermittently.

Could it possibly be an electrical short and if so is it possible to fix myself? Any help with the issue would be much appreciated!

Samsung Television: Does not turn on, Standby LED stays off

Fri, 24 Jul 2026 02:10:15 -0700

Hello!

My Samsung 55 inch OLED TV (model GQ55S95BAT) does not turn on.

Things I tried in this order:

Disconnected from power
Disconnected all HDMI cables
Pressed and hold power button for over 60 seconds
TV stayed disconnected from power for over 10 minutes
Plugged TV in working wall mounted power outlet
LED does not light up or blink
TV does not start when pressing power button

Question:

what else can I try? Is the power supply or motherboard the culprit? Can I fix it myself with minimal knowledge?

Thanks in advance!

Jabra Evolve2 85: Jabra Evolve2 85 pairing fails with "incorrect PIN" after hard reset

Thu, 23 Jul 2026 10:11:22 -0700

My Jabra Evolve2 85 headset is failing to pair with my phone. When I put the headset into pairing mode (holding the switch until the LED flashes blue), it appears on my phone's Bluetooth list but then disappears or gives an 'incorrect PIN' / 'failed requesting connection' error.

I have already tried:

1. Entering the default PIN '0000'.

2. Hard resetting the headset (holding Volume Up + Multi-function for 3 seconds until the purple flash).

3. Resetting the network settings on my phone.

4. Turning off Bluetooth on all other nearby devices.

The LED continues to flash blue during the entire process, but the connection never completes. Is there a way to force a firmware recovery via USB if Bluetooth is unresponsive, or is this a known hardware failure with the Bluetooth radio?

Boult Z20 Earbuds: One of the earbuds is not charging when placed in the case.

Experiencing an issue where one of the earbuds is not charging properly when placed inside the charging case. I have attempted to charge the problematic earbud using another earbud's case, and it charges successfully. However, it does not charge when placed back in its original case. How can this be resolved?

Thu, 23 Jul 2026 09:50:13 -0700

Hi,

I have had my LG smart tv for about three years now. The sound for it recently stopped working yesterday feb 20th. I looked online for several solutions to solve the issue but nothing seems to work. Model number. 42LB5600-UZ.AUSDLJM.

Can anyone help me solve this issue if you had it at one point with the same brand?

Thank you

Anker Soundcore Life Q30: Q30's won't turn on

Thu, 23 Jul 2026 09:14:58 -0700

Initially, the headset was switching itself off seconds after being switched on, during use.

Today, however, it didn't turn on anymore.

If I press the power button or the NC button, the blue light comes on. But it won't turn on.

When I plug in the charging cable, the red light comes on.

With the 3.5mm sound cable, the headset also works.

Does anyone know what might be happening and how I can solve it?

Service is not a possibility, because although the headphones are not yet a year old, I bought them through the official Anker website on Aliexpress and they refuse to provide repairs.

Teac GF-350: How do I fix a stuck CD drawer?

Thu, 23 Jul 2026 06:02:41 -0700

In the past, I've had problems where the CD drawer might act up—for instance, it would close and then immediately open. But now the CD drawer won't even open at all. Sometimes (but not all the time), I hear a thunking clunking noise as it tries to open the drawer, but there's no movement at all.

Many thanks in advance.
