    Samsung PN59D6500 with No Video/Power

    Good afternoon everyone. While away on a business trip my Samsung PN59D6500 decided to die, I took it apart and checked all the boards, and have been unable to find any bad caps or anything else obvious. Here is what I discovered so far:
    1) My wife called me when it failed. Basically while it was on it made a loud ferocious fart sound (As she described it) and suddenly turned off.

    2) Pressing the power button physically or via the remote does zip, the power led does a quick flash but there is no video and the TV doesn't go through its normal power on sequence.

    3) When the TV is power cycled, the power LED will flash 6 times then return to the mode I described above.

    4) The LED diag on the logic board is blinking everything 6 seconds instead of the normal 1 second.

    Tom's excellent fast track has helped greatly, and another video on Youtube helped me “possibly” track down the issue to either Y Buffer, Y Main, X Main, or X Buffer based on how the LED is flashing on the logic board but I don't have a multi-meter on-hand and can't do any proper troubleshooting. What are everyone's thoughts on this issue? Should I go ahead replace the boards I mentioned above or is the issue possibly with Logic and Main? Any feedback is greatly appreciated.

    You'll Have to do some proper testing or you'll just end up wasting money!
    --Considering some of the boards you mention can be $50 or more--and that fault could be on any board you mention--It'll get expensive in a Huge hurry if you just randomly replace this and that, with no proper methodical fault-finding!

    As most vendors Don't Test--No Matter WHAT they say-- fitting a duff board could kill an otherwise OK board in the set!--Then it gets Fun, you go round in circles and gets quickly Uneconomical to boot!

    ONLY way is by Proper Testing First.

    What is rather worrying is description of when fault occured--Loud farting--maybe a buzzing before shut-down. 'D' series Samsung are known for bad plasma panels, they develop tiny cracks near edges, lets air in, set goes Buzz due to panel down to air....

    --IF this has happened, Set is toast.

      Yeah before reading Alastairs post seeing the "farting noise" made me think the panel has just died.

      Powering the set afterwards can short the boards giving the fault you now see with the blink code

        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 UN43NU6950FXZA No power
        by mrtek
        Hi

        Picked up another TV. Samsung UN43NU6950FXZA. No power and no standBy led on. Removed back cover and:
        Main fuse = OK
        Back light LED = OK. Power them with aux power source
        LED output = OK 156V
        I do get 12 V DC out of the power supply going to the digital section but no 5V or 3.3V. PS_on voltage is only 1.8V. I have looked everywhere on the PCB , I could not find i reference for 5V output.
        Also removed connections to panel, speakers and remote but no luck. One strange thing is that even with the LED power supply working, backlight LED do not turn on...

        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...
