    Magnavox 37MF331D/37 high pitched noise in background thru speakers

    When the TV is on, you can hear an annoying high pitched noise in the background of the TV audio (checking on HDMI).

    The capacitors look good, none are noticably bulging. My question is, could this be caused by bad caps, either on the power board or main board?

    If not, any ideas on what else it could be? Thanks.

      Panasonic TX-L50B6B | High pitched noise and black lines
      by oldmanhouse
      Hi folks, I have an issue with my 7 year old Panasonic TX-L50B6B that has appeared within the last few days.

      The symptoms are:
      • A high pitched "buzzing" / "whining" noise coming from the TV when it is turned on. There is no noise during standby, and the noise persists with all AV connections removed.
      • There are noticable horizontal lines in the picture. Upon closer inspection it looks like every few rows of pixels are dead/black.


      Attached is a close-up of the picture in "test mode", to demonstrate the rows of black lines.

      Removing electrical noise introduced by fan
      by tony359
      Hi all,

      I am working on a sound processor, it tends to overheat so I fitted a fan inside. The fan is connected to the +15V of the PSU via a DC-DC converter based on the LM2596 to reduce the voltage to around 10.5V.

      Unfortunately the analogue circuitry is picking up the noise from the fan in two ways:
      1. The fan is close to the analogue section, the motor itself gets into the outputs so I'll have to move it somewhere else
      2. Even with the fan running outside of the case, there is still some noise which is clearly going back to the processor via power line....

      Onkyo TX-SR805 noise in one channel
      by MegaZAC
      Surprisingly enough, this receiver doesn't have the DSP chip issue. The HDMI board does not get hot, and sound over HDMI works fine.

      Regardless of the input, the right channel has noise that is clearly noticeable even on average volume level. The only cases when there's no noise is when VCR input is selected (some tracks on the board are damaged, maybe that's why), or if HDMI input is selected but nothing plugged into it. In all other cases, even when no input is connected I still have the noise.

      There's some logic behind it. As soon as I select an input I get only left...

      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
