    GTX 1660 - Sense Issues PCIEe POWER

    Hi everyone,

    I've got a GTX 1660 with a strange fault. On boot "PLEASE POWER DOWN AND CONNECT THE PCIEe POWER CABLES(s)" message appears.
    Checked and re-checked the 8 pin connector on the board and on the power supply side.
    I've seen that on Sense pin I've got around 3.1V without the connector plugged. If is plugged in it goes to ground.
    I've got some troubles in identifying some components. U16 has an "L2" marking and D6 a "KL7" marking.
    I will need some help in identifying those components. I usually repair graphics card with Power Stage / VRM issues and I don't really understand
    how the sense voltage drop is detected and by who.

    Thanks in advance.

          Possibly U16 is a 2 input AND gate - what is the part number / SMD code?

              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.

              Dell inspiron 17 (7786) - DP/N 09P7JP - odd power issues, starting with no power LED
              by zlr8r
              hey guys, hoping for some pointers to repair an eBay bought "faulty" laptop.

              Ill try and give as much info as I can.

              Dell Inspiron 17 (7786) Laptop
              Service Tag: 5J0NHT2
              Bios: 1.9.0

              When I received this , it would only flicker on the KB backlight for a second, then off and on.
              Then it started getting weirder!
              Sometimes when attaching the AC power supply, and pressing various pre-boot diagnostic keyboard keys... it did try to boot, in fact out of a hundred attempts, the laptop did actually boot into the Bios ! but never has...

              Original NES power issues
              by sli4
              I recently turned on my old NES to find the red light won't go on at all. When powered on it shows black bars on the tv and a loud buzz through the tv speakers. Powering it off, the buzz goes away and tv goes back to normal (white snow).

              I tested the power supply itself and it is outputting 9V as it should - first two solder joints on the board at the power port show the same.

              Here's where it starts getting funky - When powered on, one side of the 7805 voltage regulator is showing 18V and the other is about 8.7V (center 0).

              On the big blue connector I get...

              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...
