    No Vcore on GTX 1050 Ti

    Hi, I got a Gigabyte GTX 1050 Ti that may or may not have suffered some water damage (a lot of corrosion on the shield and the ports, but not as much on the board itself, which I cleaned). The card has no shorts that I can find on any of the rails but is not detected. I have 12v, 3.3v, 5v, 1.8v, pex and Vmem, but not Vcore. However, the core do get a little hot when I turn on - not to much, I can safely touch it. Obviously no voltage on the main coils. How should I proceed? I'm not sure about the proper way to test the mosfets for shorts because of the very low resistance on that card. I've attached board file and schematics for reference as my board is a little difference revision (no external 12v connector, for example).

    Hi ilod, you can try measuring the gate on diode mode red probe on ground. You should get around 0.4-0.7 voltage drop on them. If you find an odd mosfet, try to then measure the gate in resistance mode to see if it's a short. Just my 2 cents.

    Not a professional advice

      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.

      Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
      Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

      LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
      by Hakuu
      Hi There,

      This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

      After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

      Panasonic TC-P54VT25 No image. A or D board?
      by canadaboy25
      I have a Panasonic TC-P54VT25 that will power on and prime the display but there is no image at all.

      The panel is primed as there is a slight glow from the entire panel. This means the problem should be logic related. The service manual also confirms this and recommends replacing the A or the D board.

      I have tried to get the TV to display the test sequence but I have been unable to and I don't even know if this TV has a test sequence or not. I tried following tom66's instructions in post #3 on this thread https://www.badcaps.net/forum/showthread.php?t=26790. There was...
