    Distorted audio from set top box

    Box in question is a Grundig GUDSTB2000 Freeview (DVB-T) Receiver. Nothing special just wondering if it can be fixed.

    Picture is fine, channel change possibly slow, but the audio is distorted and slightly out of sync. Box has two scart outputs and a digital audio output. Audio is the same from both scarts. Haven't tried the digital audio output (not sure if I can).

    It's powered by an external 12v source which I know to be good. Inside there are around 40 electrolytics made by Secon and Chang. CPU is Zorran SupraTV ZR39162PQGC.

    There was one bulging Secon cap (1000uf 10v) next to the tuner but replacing it made no noticeable difference. I've replaced 3 others close by but still no change.

    Does this sort of problem sound like it would caused by bad caps? Don't want to go much further with it if it's more likely to be something else.

      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...
