    Panasonic TX-P50UT50B Red Green Blue Pixels

    Hi guys I've got the above tv it had a new SS board a few weeks back as the original one had gone bad


    Anyway I've noticed today on black borders or with no video signal it looks like noise is on the background but if I go close and look it's all green blue and red pixels making the noise


    Any ideas what this could be ??

    If I run the scrolling bar test it looks perfect no colours on the black parts it's pure black

    I'm not sure how to access the service menu but can do it with help I'm sure

    ATi Radeon 9600XT (256MB, AGP 8X) - Blue Pixels and Corruption
    by TechGeek
    The title basically says it all. The card displays randomly placed blue pixels on the screen (especially when rendering 3D stuff), the right edge of the screen is garbled in VGA mode, and it sometimes fails to re-initialize on a reboot or when trying to wake up the display. Bad VRAM? Dud GPU?

    LCD TV Green/Pink screen problem
    by jimjoe123
    I have a Dick Smith 37" LCD TV, Model GE6804. I am using it as PC extended monitor only.

    Problem is while watching tv, I hear a semi loud click(like a electrical breaker tripping due to overload, just sound like it but no actual electrical overload), then screen is covered with green or pink. I can still see the original picture image but overlayed by green or pink. See attached images. Pink.jpg is what I see, and Normal.jpg is before green or pink screen, What I captured was pink screen, but about 80% of time it's green and 20% of time it's pink.

    Then each time...

    Panasonic Heatpump Dryer Repair
    by BigPete
    I picked up a Panasonic NH-P70G2, though it would apply to the NH-P80G2, NH-P70G1 and NH-P80G1 models as well, as maybe some other models. This one was coming up with a H86 error. After lots of testing and googling it was an error with one of the thermistors in the condenser area.
    The attached French service manuals is incorrect, TH11 is gray and is a 95k thermistor and TH12 is black and is a 35k thermistor.
    In my case TH12 was bad. I was able to get a 35k thermistor on AliExpress. It's 6mm in diameter.
    Unfortunately the whole machine has to come apart to fix it.
    I have...

    Panasonic TX-P42G30E green light blinking, no video, no audio
    by ItepK
    Hey everyone!

    I've gotten this TV for free, neither have it seen a TV repair man, neither have it been opened before.

    This post describes my entire troubleshooting process of this TV.

    When I turn it on using the ON/OFF switch at the side of the TV, the light rapidly flashes green, then it stays on, but it does not react to any of the remote buttons, side buttons, and doesn't play audio.

    I've taken the unit apart, and I've started to check some voltages:

    • On the P11 connector, there is 15V DC only for a brief moment, then it goes

    Panasonic 55DX600u repair help - no display fast green then slow red led flash
    by fixxy88
    Hi everyone. I've been given a dead Pana 55DX600u that I hope to save from landfill. I suspect the tcon board or UC1 on that board.

    Set will flash green led and attempt to start, backlight gives a brief flash then set shuts down and red led flashes slowly. Voltages out of PSU look ok. TCon board gets 12v at fuse when attempting to start and 3.3v on L1 but main IC gets warm very quickly (heatsink/cover removed, felt with back of hand) during the second or two the 12v is applied before PSU shuts down. TVS diodes on lvds input lines are not shorted, no caps appear to be shorted. ...
