    Todd Engineering Sales PC45B Power Source

    It's a 12VDC to 120VAC power converter on a Jayco 5-wheel camper that I fried.

    I was going to repair it when I notice this part, circled in red, was blown. The part's info was on the side that is missing, so I can't look for a replacement.
    It's more than likely a transistor.

    If anybody has this unit, or have schematics for this unit, can you look and tell me the information on this part?

    It's marked as U2, which can be a voltage regulator in a TO92 capsule.
    Try to make a circuit schematics, it can help.

        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...
