    HP zbook 15 g2 - sound ( noise) problem

    When I use earphones , the sound from the earphones has a noise problem. When I stop sound( e..g put video in mute mode) the noise remains a little longer and then stops. The problem is ONLY when using earphones.

    Under Linux it is the same as with Windows 10.

    What can it be ? Thanks for help

      connect a desktop speaker to the earphone connector of the laptop. Then check the output sound.
      Possibly, the audio processing circuit of the laptop got defective.

          Thanks for your reply. Do you mean a capacitor on the path from audio chip to earphone connector can be a culprit?

              yes, that is possible. But I have not enough experience on audio controller ICs.

                  Philips HTS8000 home cinema noise problem
                  by courtcircuit
                  Hello

                  I have since a long time a Philips HTS8010S/01 which has been old but was doing the job.

                  Since a few days, it starts by making a weird "static" nois when switches on for a few seconds to a minute and then works like a charm.
                  Noise loudly outputs from the 3 channels, even if no signal is sent by the controler.DVD to the subwoofer/amp unit.

                  I was thinking of a soldering that was starting to be damaged and that was only doing the job after a few seconds of heating, most probbaly on the power board
                  Removed each of tyhe boards
                  ...

                  Hi.

                  IΒ΄ve been given an old CRT from Panasonic, itΒ΄s almost new, it was storaged and almost not used since bought.
                  It is imaculate inside, almost no dust or debris inside.
                  The picture is good, but I have no left sound channel, I tried all the inputs, outputs, even on headphone jack. In AV2 I hear sound from right channel but no image, on tv tuner only right sound channel, the same for AV1.
                  So I started to look for a service manual, I found one, and started from the beginning.
                  Most of the times the caps are the problem so I orderer all the caps for all boards,...
