    Hanns-G HG281D no display but power.

    Hey guys, I have the Hanns-G HG281D with the FSP217-4F02 power board, with no display or any sort of life coming from the panel itself or backlight, however the power light will show blue when plugged in, go to yellow standby after a short time, and will turn blue again when the power button is pressed, however, the display will not work at all. Does this sound like the known power board issue?

    I have some pics:

    It could be the inverter is bad (bad lamp, bad HV transformer, bad driver transistors).
    Or, it could also be the caps on the video board, which are notorious for going bad. If you have read that other big Hanns-G HG281D thread, this should certainly convince you to recap the video board.
    And, yes, it could also be the power board not providing 12V and 24V to the inverter board. But I have some doubts it's the power board. Either way, if you have a multimeter, set it to measure DC volts and check the voltage on all of the pins on those white connectors on the power supply board. Then post what you find here. Like this, for example:

    Connector CN###
    pin 1: xx Volts
    pin 2: xx Volts
    ...
    and so on.

        Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
        by Tynan Dill
        I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

        Upon bringing it home and plugging it up, it showed a standby light.

        I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

        The screen seems to blackout and stay black, but with a flashlight I can see the display.

        With my Playstation 4 connected via HDMI, and running a game I can hear sound.

        Assuming...

        [HELP] Acer AN515-55 (LA-J871P Rev: 1B) – Board won't power on after GPU investigation – Suspecting Super I/O or PCH

        Hi everyone,

        • SNID: 03902728734

        Initial Issue


        The laptop initially presented graphic issues and driver failure (Code 43) for the GPU.

        After preventive maintenance (cleaning, thermal paste, etc.), it powered on normally. We disassembled it again to inspect the GPU, reassembled...

        Hi and thanks in advance for any input you might provide!
        I have a Sceptre U550CV-UMRD8POTV83BB 4K LED (this is a dumb tv) that I bought new in August 2021, so It's just completed 3 years.
        Main power board model: TP.MS3683.PC821 T-Con board: N4TP546UHDPU2L_BO

        Last Sunday I was watching a dvd and fell asleep for about half hour, when I awoke the tv screen was black and couldn't get the dvd menu to show, so I changed the input to antenna and had sound but no picture, turned it off. I then got online and found this great site! ....read many troubleshooting tips and this...
