    MAC Display A1316/A1407 appears to be dead even after replacing the PSU three times ?

    I have an older 27" MAC Display that I simply loved.. Sharp clear display.. Then it crapped out on me..

    Long story short, I assumed it was the power board and replaced the PSU three times.. STILL completely dead..

    So, I was wondering.. Would a bad VIDEO BOARD cause the same doornail dead symptom???

    The thing is, this MAC monitor doesn't have any indicator that power is on.. In the past, I have only known it's "ON" when there was a pic on the display...

    I haven't checked voltages, as I am not sure where on this PSU to check..

    About the ONLY thing I have done is confirmed that the fuses are not blown on the PSU boards I have..

    Any assistance would be most appreciated..

      I have the same problem, did you check the capacitors? I have changed them all but I don't have dc output.
      Be careful with this power supply because there are 3 capacitors that are 420 68uf and could be dangerous. If you can upload an image I can show you what I have checked but mine is still dead.

              Laptop dead after replacing BIOS Chip
              by bigbadbios
              Hi all,
              I have an ASUS ROG Strix G533z 12th gen i9 laptop that had no video.
              I suspected BIOS corruption, so I took the main BIOS chip off and replaced it with another one that had a clean BIN I bought online.
              After doing so, the device is stone dead. Even with the original chip fitted back.
              I sent it to Northridge Fix (I am based in US) and he said no activity on thermal cam and no power issue is not directly firmware related.
              Can anyone help? I'd love to save this fairly new and powerful laptop.
              Thank you!​

              Problem

              This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

              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...

              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...
