Ok I got 5.1 system in the bedroom, in there I connect directv, blu ray to 5.1 inputs for sound, works good, now out in the living room I got directv and I'm getting android tv, there no sound out on android tv unless I connect dolby digital out from the hdtv itself, so what I'm saying is there a difference running sound thru tv then 5.1. Like a pass thru from tv to surround sound etc. I just figure it out have to get a optical cable for directv and run the android tv from hdtv to 5.1 dolby rca plug

so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!!
what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol! 
i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing... -
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 -
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... -
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... -
Hello, I got this AVR for cheap and tried to fix it as a fun and learning project.
First the audio video receiver would turn on but had no sound at all, but no "PROTECT" message.
So, I opened the metal case and noticed some marks showing that some liquid has been spilled on the amp. Those water marks were found on the main board and the digital board.
I disassembled everything, then checked every single cap on every board of the amp and recapped when needed.
Also fixed A LOT of cold solder joints and also done some modifications,...
