    VIERA TX-PR42GT30 Noise (black pixels)

    Hi.
    Purchased TV with 7 blinks.
    I repaired SN Board, everything works fine but this noise... It is clearly visible on green and red patterns.
    is that normal? Lifetime is 9500 hours.
    I have U30 tv with 10000+ lifetime and can't see any noise...
    Tried to play with VSUS on powerboard - no difference (from 208 to 219)

    Its normal but its not normal if you see it from 2/3 meter distance.

    Vsus has to be 215V from factory. U30 is a different panel and technique. All these ST/GT/VT models have the same "issue"
    I only repair Panasonic plasma tv's! Currently owning a TX-P55VT50 and still searching for a ZT60!

        No this SC board does not have potmeters. Only on the powerboard. You could set V-sus to high in service menu but this is normal , i have it on all my Panasonic tv's. ( Except cheaper sets like U30 ).

          My friend have 50GT30 with ~5500 lifetime and no visible noise.
          I see that noise only when I close to the tv - something like from 30cm.
          I can see that only on the patterns from service menu. I see nothing on a usual content like movies =) Just I wanted to hear another opinion.
          Thanks

            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...

            Dell G3 15 3500 - Battery bug (black screen and flashing keyboard backlight)
            by HTR-Informatique
            Hello,

            YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo

            I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.

            On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.

            I also changed the screen because the PC fell and the screen was broken.

            I changed the battery with a new and original battery.

            I also had corrosion/oxidation on the...
