    Proview PL926Wbi completely dead.

    I have a proview PL926Wbi. It shows no signs of life. I looked through the board replaced the main rectifier and bridged the main fuse.

    Now I have 5v going to the logic board and 15v going to the two 3055s. When I hit the switch nothing happens. The fuse on the logic board is good.

      Was there a question there, or are you documenting a process that DIDN'T work?

          I guess both, I was really tired. I put 5v to blon through a resistor and the bulbs light up.

              I fixed it. Logic board has a 3.3v ams1117 regulator. It was only outputting 1.25v. Replacing it fixed it. If you have a problem with this display, check this regulator.

                  Well done. And thanks for providing the information.

                      NxB- Thanks for the suggestion. I have the same model monitor with the same problem. I'll check mine out for the same issue!
                      Stupidity should be a crime, especially for drivers. I have NO patience for them.

                          Dell E6540 laptop completely dead after dssasembly
                          by max-power
                          Hi, I disassemble my laptop to replace the speakers, to access them, you have to remove everything including the heat sink and fan, unscrew the motherboard, lift it up a bit to access the speaker wire.
                          that was not the first time I dissasemble it, i did replace the same speaker a few year ago and I repaste it last year, so I had nothing to worry about. but when I put everything back together, its completely dead.

                          After a bit of investigating, i found one pin of the status led ribbon cable that was unglued from the cable and bend touching another pin, I bend it back at his place...

                          A2681 M2 MacBook Air Dead Logic Board
                          by yuuki47
                          Hello...

                          My sister purchased an M2 MacBook Air a year and a half ago. While she was using it a week ago, it randomly shut off and no longer powers on. There are no signs of life and not even the MagSafe indicator LED lights up.

                          We took it to Apple and they disconnected the battery and tried a bunch of stuff before they declared the logic board "brain dead" and quoted us about £567 to replace it. Typical of them...

                          eBay replacements run about £367 with the Touch ID sensor included.

                          I did consider to probe the logic board for shorts...

                          T480s random shutoff and then completely dead
                          by wangbreeze
                          Hello Gurus,

                          I got a ThinkPad T480s. It was running fine but suddenly started random shut down. When it turned off, I had to push the reset pin to bring it back to life. But it got aggressively worse and became completely dead. No charging light, no life.

                          I did some initial diagnostics with just the board (no battery, nothing attached, and no CMOS battery as well)

                          Initial testing of the coil resistance seems to indicate no dead short. The only low resistance I measured was at PL701. It reads 38 ohms.
                          charger gave - 20V - ok

                          Completely dead MSI z490 tomahawk
                          by pavski
                          Trying to troubleshoot MSI z490 tomahawk board and would appreciate your help. The board is completely dead and shows no activity when the power button is pressed.

                          I have tried to look at the Superio, the PSIN signal seems to be correct (goes from 3.3V to 0 on button press) but the voltage on PSOUT pin is quite low. I

                          t is only 0.8V which seems to be incorrect but goes to 0 when the button is pressed.

                          Can you please let me know if this is indeed incorrect and what else should I look at next?

                          Thanks!

                          Lenovo Thinkpad T14s completely dead.
                          by Andreasbest
                          Hello.
                          I received a T14s Gen1 ( NM-C891 motherboard ) that is completely dead, no indication of life at all.
                          I tried hard reset without RTC battery and short both pins of it for 1 minute but no luck.
                          Since it's type C connector i have no idea what to measure or where to inject voltage, so any advice are welcomed
                          Thank you in advance!
