    Phillips 47PFL5704D/F7 Audio

    I replaced 2722-171-00692 Power Supply. The 18v audio power is good.
    When I plug the set in and supply a HDMI input the there is no audio. Turn up the audio with the remote and it does not work untill you hit 60 percent. Then the audio works fine. Turn on power and it works fine. It only when set losses power does it do this. As long as it stays plugged in and dont lose power it works fine. Any Ideas? The set was not working when it came in and they did not say anything about this . Strange

      Access the service menu and check for a factory reset option, if that fails, also check for an option for the "audio table" which lets you select a different profile for the volume control.
      Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
      For service manual, schematic, boardview (board view), datasheet, cad - use our search.

          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"...

          Denon AVR-2700H audio stops while receiver still works
          by Cornito
          Hello team,

          I've got a new issue with a Denon Avr-2700H.
          After several minutes working, receiver stops playing sound with a poc eared in the speakers.
          Receiver still work and display video with error message on display.
          Seems to me that is the main output relay.

          I'm looking for the service manual that I can't find for the moment.

          Does somebody have it?

          Regards...

          what i went through dealing with my mobo with dead onboard sound!
          by ChaosLegionnaire
          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...

          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...

          Mi TV 4 Pro-Samsung Panel LSC550FN20 - Video problem, backlight and Audio works fine.
          by SolarFlare
          Hi,

          My barely 3 year old TV has stopped displaying video, although the video output comes for a few seconds after turning ON which displays the manufacturers logo then shows the home screen (all this with some blue flicker) then the video goes blank and the screen is dark blue with the backlight on. The audio output works perfectly and the TV also takes in voice commands(smart TV).

          The TCON board has the following Chips -
          Samsung VTU63A0
          RT6939 - 2nos.

          and all these chips are getting real hot within a minute, I dont know if this is normal....
