    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...

    Argon SA1 audio amplifier power-supply - fuse blown after fixing the short?
    by Babbar
    I found a project in the electronics trash yesterday. A nice Argon SA1 audio amp with some electrical issue. Took it apart and saw that the 4A250V fuse was blown so started lifting components to find the short. Eventually got to two MOSFETs (model FTA14N50C) that are shorted and when i took them out the short was gone.

    Now i didn't have any replacements of the same model of course but i found a couple with pretty similar spec i thought (K10A60D & K12A50D) and put them in. Also replaced the blown fuse with a 3.5A250V one. Checked another time for short circuit and plugged it in....

    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...

    Edac/Drobo Power Supply Fuse
    by vletr
    Hello,

    Looking for next steps on troubleshooting for an external power supply made by EDAC, model EA11011H-120. The power supply was dropped onto a tile floor and initially and briefly worked but the led power indicator light faded out and the power supply showed no signs of life since.

    In disassembly, I found that the large capacitor had leaked and was reading open when measured. The fuse nearest to the AC in had also blown, with no continuity. I ordered a new capacitor and fuse and replaced both, but on power-up with no load the fuse immediately blew.
