    Pyle Pro PTA1400

    We have a small community center where locals gather for a monthly jam session / community music night. The makeshift sound system includes a Pyle Pro PTA1400 amplifier.
    The left side audio has been intermittent, no sound when turned on, crank up the volume and there would be a defining bang and it would work normally through the evening with normal volume control. Would have to repeat the procedure the following month, almost like something was momentarily healing. The amp has now given its last bang and channel A is dead. Did the normal cable swap, it's definitely dead, not a cable problem. Have signal to the amplifier board input, but no output. Wiggled connectors, tapped on things, flexed circuit boards, no response, nothing obviously burned up. Any suggestions as to where to start? I have written Pyle requesting a schematic, no response yet, might someone have a schematic they could share?

    Thanks in advance!

      Sansui Integrated Amplifier replacement volume control troubles
      by Coert van Dorsten
      Hi all you clever electronmic gooroos!

      I was wondering if you could help me with the below issues Im having on a Sansui Integrated amplifier. I bought this unit as a project to repair as Im playing around with basic electromics.The unit has a faulty volume control pot. The service maual refers to a 150K Logarithmic pot (A) tapered stereo. Im struggling to find this value. Seem to be a jump from 100K to 250K. Im now trying a 250K pot. It works but the problem is that as the volume is turned up from starting at Min the Left channel will come on first just slightly before the Right...

      Sony HCD-HX80R Amplifier Volume Control Problem
      by crackedprint
      I have a strange fault on a Sony amplifier. The volume control varies the display from MIN, then 1 up to 30 and then MAX as expected. At MIN there is no sound. However, at 1 it is quite loud and increasing above 1 does not change the sound level.

      I have tried a Cold Reset as per the service manual.

      I have looked at the I2C clock and data to volume control chip IC501 (BD3499FV). Data is only sent to IC501 when the volume is set to MIN or 1. At any other setting no data is sent to IC501.

      I have looked all the way through the service manual and tried many online...

      Vizio D65x-G4 Volume changes on its own
      by karthur
      On this Vizio D65x, the volume will change on its own. I don't mean like during commercials where the volume will increase. I mean its like the (+) volume button on the remote is pressed and the actual volume dialog is displayed on the screen going up. It will do this, then the volume may start going down. It might go all the way to "0"or it might stop at a different number, then start going back up. The whole time its doing this, the volume dialog is shown on the screen.

      It wont do it until it has been "ON" for 20 or 30 minutes, so it does seem to be heat related....

      Kenwood KR-A70 Receiver Balance changes with volume controls?
      by freethink
      I have a Kenwood KR-A70 Receiver on the bench, and the digital volume control is acting very funky. When I adjust the volume, the balance also changes. Volume Up = balance goes Left, Volume Down = balance goes right. Has anybody ran into this issue, or know what the problem might be?

      Marantz SR5007 popping on volume change and mute in Direct Mode
      by BigOof
      Hi,

      I bought a used Marantz SR5007 and it's giving me some issues that I can't seem to really place. It functions well in most settings, ARC mostly works, it has no issues driving my speakers in any of the digital input modes, but I'm having issues running analog inputs in direct or pure direct mode. For some reason in this mode there's distortion for every volume increment I give it, but once the volume is stable it has no issues. Muting creates a loud pop, switching to another source also causes a pop and so does turning off the amp in that mode. Again, no issue in the digital modes....
