    WTF is this?

    Got Gigabyte GA-PE667 Pro as probably dead. All components were fine, just the board. OK, I have waited for POST card to have a look whether it is completelly dead or what. Booted on first try.

    Today I wanted to have a look at some memory (again fully OK, just need to have a look at some parameters). Board appears to be completelly dead. What the hell? Did you ever encountered such a behaviour?

    I have the feeling CPU socket is too loosy but I tried to swap two CPUs several times, it should catch up at least one time I think…

    All bigger caps are good, Rubycon and Sanyo. Only the smallest ones (100 uF) are Choyo…do you think they may be so important they make chipset look dead?

      How can I be sure that my EC chip is dead?
      by double_DD
      Hi all,

      As the title suggests, how can I be sure that my EC chip is really dead?

      I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.

      Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard...

      by disorder

      history : as always hdmi port and usb ports destroyed after unplugged
      after change them, ps5 dead too : 1 beep, no blue light. after inspection 1.8v power was shorted, and because of dead panasonic chip. after remove it : no short anymore
      so i changed it
      now i have got 5v stby,, 3.3v stby, 3.3v power, 1.8v power and no short on them
      but the ps5 is dead again : 1 beep, near 10 seconds with power lines and then off, no blue light ...

      Finding a dead short component
      by Beton
      Hi guys!
      I searched for the term "dead short" in the forum but no specific thread came up however if I'm just blind and couldn't see the thread talking about this please forward me to that direction.
      So my problem is I don't know how to find the source of a dead shorted voltage rail. Dead short = ~0 ohm resistance.
      I have two VGAs (HD 4850 and HD 4870), both dead shorted to ground on the memory rail. I have the boardview file for the 4870 and the memory rail consists around ~7892346 capacitors...
      I have a bench PSU and if I try to inject voltage the voltage...

      Chieftec GPS-450-AA with dead 20N60C3
      by zunasthegreat
      Hello everyone hope all doing well!
      I have this PSU (GPS450-AA delta oem) around for like 4-5 years and I had it recapped early 2020 or 2021 with mostly UCC KY and Nichicon PW's. The bulk was and still is fine, the original Ltec's were bloated and empty. The previous issue was some major coil whine noise and at times random shutdowns when going idle. Today it started tripping the mains breaker and I think I have dead APFC mosfets (20N60C3). Right now upon checking I have the Q1 and Q3 FETs dead so far and I guess those are responsible for the PFC circuit. The only thing I care is If there...

      MSI Raider GE75 - Not posting, probable dead CPU
      by FiguringITout
      Hello, today I'm working on this lovely MSI Raider GE75 gaming laptop which I bought to flip. Unfortunately, I believe the CPU is toast but I wanted a second opinion before I chucked it into my spare parts bin. I will not have most tools with me today as I'm away from my workbench but I have the basics (a good multimeter, a horrible iron, a solid screwdriver, and my trusty thermal cam). I do not have the original 230w charger, but I have a Dell 180w which was sold with the device and reportedly "worked fine for them".

      Specs: I7-10750H, RTX 2060, 32GB RAM (unknown manufacturer)...
