I have a logitech g935 headset and the weird issue is that one side does not work on wireless but when plugged in with the 3.5mm cable it works fine so I don't think it's the wiring?. I have already updated the firmware and checked all the windows audio settings to make sure the balance was equal etc so I don't think it's a software issue. Should I assume it's a logic board issue? I did take it apart but not sure where to troubleshoot on the logic board. I do have a fluke meter and familiar with soldering if needed.

The Problem: This player has a toggle switch to select between Stereo, Mono R, and Mono L. Regardless of the setting it outputs the sound to both the L&R audio jacks. In the Mono R position, the audio output level is normal (from both the L and R audio output jacks), in the Stereo position the audio output is about half the volume, and in Mono L, it's about 3/4 the volume. Something about putting it into Stereo mode is causing the volume to drop significantly and I can't figure it out.
The player processes the audio signal using two different reference frequencies. The "R"... -
Hello all ~
Hope this finds you well. This LG 82UN8570AUD (April 2021 model) 4K UHD television has full audio capabilities but video is compromised / problematic.
When I picked up this large LG tv it had a full black screen upon startup. Previous owner said it just went black one day. No popping sound or anything else of note.
I got the display to work by taping off several traces of the right-hand side ribbon cable on the TCON that leads from TCON to PANEL. However, despite dozens and dozens of attempts to find the right combination / range of traces taped... -
Have an issue with my momentum wireless headphones. Bought them on ebay to try out repairing them - have done component level repairs on laptops and other small devices, so figured I would give it a shot - but I know very little about audio circuits and troubleshooting - so please forgive my lack of basic terminology knowledge and any help is appreciated.
An overview of the symptoms is listed below with a more detailed outline after that:
- Immediately on power on - slight static in right side of headphones
- Static only lasts for 45 seconds to a minute

This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.
Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today.... -
Hi All. I had a Roland KR-3500 Digital Piano (similar to the KR-4500) that exhibited a Crackling audio sound on all keys. After reading somewhere about someone with a similar issue who had replaced all the Electrolytic caps I decided to also go down that route. (Spoiler : It worked !) After some basic troubleshooting I determined that it could be noise feeding thru from the Keyboard scanning since the Demo tunes played back undistorted and the Audio amp / speakers were fine ( Inserted an Audio signal into the rear Audio input). After extracting the main board from the shield, I replaced 7 Capacitors...04-30-2024, 08:20 PM
