Re: lg 50pg4000 loses sound remote stops working and switches off
How to test a headphone output? Hint, it involves a pair of headphones and careful listening...
Digital audio out do you have a 5.1 AV Receiver, soundbar, etc?
It might be entering e.g. hotel mode automatically for some reason.

You should do such checks as a matter of troubleshooting any electronics, regardless of fault, unless you are -certain- it is not related to the power board.Leave a comment:

Good day ladies and gentleman!
I am currently trying to repair a Grundig Vision 9 37 9880 T USB LCD TV for a friend that has a weird audio problem. Basically everything works fine except for the heavily distorted sound when the Subwoofer module is connected and there is a buzzing sound coming from the PSU PCB.
This seems to be a rather rare TV so there is not much prior on topic help to be found however a service manual is available at the usual sources (Electro Tanya i.e.).
I think the PSU buzzing comes from one of the coils near the bridge rectifier but... -
Yamaha PSR EW400 piano intermittently loses sound and shuts down.
Youtube people recommend verifying that the DC jack's solder connections aren't broken, and the replacement of a couple of capacitors in the vicinity of the DC jack. While these solutions might work, I'd feel a lot more secure if I had a schematic to help me check the status of the myriad components.
Schematic and suggestions are welcome. -
Hello to the forum.
My name is Christos, I am new to the forum here and i am posting from Greece.
So i have this old German sound card from Marian, called Trace Alpha. To be exact i have 2 of them and i use them professionally for my small FM radio station here. The first one works like a charm, but the second one does not work at all.
To be more specific in the same exact pc with windows 7 (i even tried 32bit) the one works while the other doesn't.
So i tried asking for a schematic from the company and they would not give me one. Instead they... -
