    LG 66UH5500 won’t power up

    When I push the power button the LG logo will flash then the tv goes black and the power light will flash twice and go dead .

    Does this sound like a back light problem or more like a power or main board issue ?

    Any help would greatly be appreciated

    I had the same problem with this model but 50 inch. It's because of one burnt backlight. read this thread: https://www.badcaps.net/forum/showthread.php?t=67154

        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.

        troubleshooting microsoft surface pro 4 no power no led charge light
        by ipatch
        hello, �� i have been sitting on some microsoft surface pro 4 tablets for a while now. i was originally tasked with replacing the battery in one of the tablets, and ended breaking the screen and logic board in the process. decided to buy another tablet with the same specs. got that screen off successfully of the second tablet. the logic board appeared good, but i guess i shorted something out in the installation process of the logic which i've read is a common issue if there is no barrier between the logic board and battery pins. all that said, i ate costs of the repair and have...

        Dell Optiplex 7490 AIO - red power led after flash
        by Mark01
        Hi guys,

        This is my first post! 🚀
        I have no idea what I’m doing, but I’m learning by trial and error.

        I’m currently working on a Dell Optiplex AIO 7490—one of a bunch of AIOs that mysteriously failed to POST just a few days after the warranty expired. The original issue was that the PC worked fine until it was rebooted, after which it got stuck on a black screen (no backlight), with fans spinning at normal speed and a solid white power LED. Forcing it off by holding the power button would just cause it to switch on automatically and get stuck again on...

        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...
