    JVC lt-32vah3000 no sign of life apart from Digital Audio Laser port is lit RED

    HI,

    Have this set that does not respond to remote functions. It is either bricked or main faulty as the power supply is on and mainboard supplies seem present. I have noticed the red light from the digital audio out.

    This is an android on a vestel main board 17MB171

              Help troubleshooting an audio problem with an RCA SGT-250 CED Player
              by samson7point1@yahoo.com
              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"...

              Roland KR-3500/4500 Digital Piano. Crackling audio sound on all keys -Fixed
              by i_am_patch
              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...

              Schematic Digital Audio mixer RCF type M18
              by Bektronics
              Hello dear audio friends.

              I am feverishly looking for the full electronic schematic (not a block diagram) of the RCF type M18 digital audio mixer.
              The device does not make a WIFI connection with my Apple tablet and yet I have already installed the recent app on it.
              I suspect that there is a problem in the mixer itself with the WIFI card and of course I would like to see this on an extensive schedule before opening the device.
              Thanks in advance if anyone can help me with this schematic.
              Of course, all information about this digital mixer and possibly references...

              Vintage SONY Digital Clock Radio ICF-C12W no audio
              by UserXP
              Dear all,

              I have this old radio clock by Sony from the early 80s, I guess. The clock display works, but is dim, the function board appears to be OK - but the radio unit shows no signs of life. It doesn't produce a single noise, crack or anything from either FM or AM band. It's like it doesn't even power up.
              i opened the radio and it is full of some TRACON gray capacitors. They only have their negative strip printed, voltage and capacitace markings - no series, no temperature marking, nothing else.
              My question is, do you know of this brand of capacitors and how bad are...

              Monitor Audio RSW12 - Green light but no audio
              by MOSSEP
              Hi

              Im hoping someone might be able to give me some idea of what may be wrong with my Monitor Audio RSW12 Sub.

              Ive owned it since new in around 2002, so would really like to keep it running if I can, it was the first ‘decent' bit of audio equipment I ever purchased and is a little sentimental.

              The issue I had was that it would power up with the red light, but sometimes the green light would not come on and I would get no bass from it. If the green light did come on though, I would get sound out of it.

              I have already tried replacing all of the...
