    MSI Claw A7 no power

    Hi all,

    i got a MSI Claw "consoles" which drawed 5v without doing anything else. I took the board out and found the blown up cap from the picture.
    Can anybody help me to id it? I think i saw some with the J7 reading on a MacBook A1466 donor board.
    Ist there anything else i should look for which possible damages?

    Cap was changed (sorry made a mistake in my post replaced it with the same J8) but still only getting 5V with minimal ampere jumps.
    Can this be a faulty Power IC or anything else i can look for? There are no shorts on the board and mosfets also look fine.

      Final Update, i gave the PD chip TPS65993 a reflow and now i get 5V and 0,3A and can meassure 5V in the board. But the chip ist getting hot 50C and doesn't switch voltage so i guess it's my problem.
      I can't find any replacement and only found a TPS65994A which seems similar. Anybody has an idea what i can try?
      Could a full reball help in this case?

        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...

        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...

        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...

        What capacitor should I purchase for Power Supply of obsolete game consoles?
        by chth96
        hello.

        I have Sega Saturn and 5 years ago, I recapped all of capacitor in the Power supply, Because At that time, It frequently freezed black screen after SEGA logo displayed.

        It hardly ever freezed after I finished to recap all of caps in the power supply.

        But Yesterday, It did not show any screen at all and its green power LED constantly blinked.

        To my surprise I found that all of two NXH 10v 2200uf capacitors in the secondary area of Power supply have been bulged and It measured 57 mF and 75 mF capacitance.

        It seems that quality...
