    Noise filter question...

    Can I replace GL-2080FVP-XLW with GL-2080FVP-L ? It appears that the form factor of the harness requires a switch of the L and N female quick slides. -XLW has a metal (grounding?) contact plate soldered to it's body. -L does not.

    if its going into a device with a metal housing yes. and yes that is a ground tab.

    You must have a sad, sad boring life if you hate on people harmlessly enjoying life with an animal costume.

    Sometimes you need to break shit to fix it.... Thats why my lawnmower doesn't have a deadman switch or engine brake anymore

        Problem

        This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

        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

        Modding HPF filter
        by madan1
        Hi everyone.
        Recently scored a dead amp from a mackie srm1801 subwoofer and after fixing it, now I'm thinking about a home cinema/party subwoofer project.
        Most likely I will use a 15" JBL woofer, which I already have and a diy box.

        After reading the mackie user manual, I noticed that it has a 40hz HPF (labeled as "36Hz BUTTERWORTH HPF" in the SM) to protect the speaker from low frequencies. Indeed this seems to be good idea for the intended usage - professional music subwoofer, but bad for movies, where one would expect to "feel" the SUBwoofer....
