    Samsung PN50A550 No Power

    Hello Everyone.

    I have a Samsung Plasma Tv with power problems.
    This Tv come to me with a power problem like turn on - turn off.
    Everything on the Power board looks ok. (caps, no burning signs, etc)
    So, I did a sample test shorted pin1 - pin 3 from main board ribbon cable and short pin3 and pin4 over logic board.
    So, the tv keeps on for 5 minutes. After this time, I took this tv of to my bed and I try stand over the floor reclined on the wall.
    As soon I turn on, I saw a short(bright light) comes from y-board or Buffer Boards.
    So now the tv refuse turn on making clicking noises.
    Stand by keeps 5volts.
    No generate vs or va voltages.
    The fuse fs803 was blow out and I try to use another with higher amperes, but still blow everyone that I used.
    Any Ideas.


    Thanks

    Microsoft Surface Pro (5th gen) model 1796 - no power
    by PantherDave
    Hi all!

    I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅

    I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

    Asus Probook P5440UF-XB74 power issue
    by GLISIT
    Hi all,

    TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!


    I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

    A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about...

    Samsung TV won't turn on ... keeps cycling the power relay on & off
    by Journey11
    Hi All,
    First time posting here ... my name is Kevin but my friends call me Journey.
    I have a Samsung 75" LCD model UN75RU8000FXZA that I don't remember the original fault other than it wouldn't power up anymore.
    After it sat for many month's I decide to look at it again. The motherboard seemed to have power regulation issues. After much fussing I decided to just get a new MB.
    It came a few days ago and I installed it now just cycles the power relay on and off ... when on the backlights light up and then dim and then relay kicks off and the whole things starts again....

    Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
    by sam_sam_sam
    I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

    One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

    Samsung BN44-00262A H37F1-9SS power supply help finding blown value components!
    by cheeky2
    This Samsung combined power supply and inverter was replaced a while ago from a Samsung 37inch LE37B530P7W TV. However I would like to repair this one.
    I have replaced the Mosfets Q1820 and Q1821 ( FDPF7N50U) which were both blown and the fuse FM802S. The schematic for this power supply that is attached doesn't relate to this power supply as the driving transistors and diodes are D1830, D1831, D1832, D1833, Q1811 & Q1810 are nowhere on the schematic!
    Does anyone know what the components for D1830, D1831, D1832, D1833, Q1811 & Q1810 should be? I ask as I did change the Mosfets...
