      Welcome to the site. A good start is as I mentioned in your initial post was to provide good pictures and any voltage measurement you have taken so far. We do not have the set in front of us so the information requested would help.
      Willing to help but I'm no expert.

                      Is there damage to this component?

                      Are you certain you have 35V at P5 (STBY5V_ON)

                          This looks like a bad PSU from what I've read so far. Do you want to repair the PSU or simply/easier replace the PSU?

                              I picked up a Panasonic NH-P70G2, though it would apply to the NH-P80G2, NH-P70G1 and NH-P80G1 models as well, as maybe some other models. This one was coming up with a H86 error. After lots of testing and googling it was an error with one of the thermistors in the condenser area.
                              The attached French service manuals is incorrect, TH11 is gray and is a 95k thermistor and TH12 is black and is a 35k thermistor.
                              In my case TH12 was bad. I was able to get a 35k thermistor on AliExpress. It's 6mm in diameter.
                              Unfortunately the whole machine has to come apart to fix it.

                              Panasonic TC-P55ST50 8 blinks then no blinks
                              by Andre Gilbert
                              Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing here🤔?
                              Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.

                              Problem with PANASONIC CF53 laptop after changing BIOS settings
                              by AquaMan Ua
                              Hello. I am asking you for a hint on how to solve the problem with my touchbook Panasonic CF53-2 standart model. After setting up the BIOS, the laptop displays the wrong image until Windows loads. (More precisely, it displays, but distorted, instead of the Panasonic image immediately after turning it on, it displays what is in photo #1 in the attached file) Then the image appears when Windows starts loading and then there are no problems with the screen until the reboot. If you enter the BIOS, just a black screen. If you connect an external screen, the image on it is the same as on the built-in...

                              Hi everyone!
                              I happened several times, in the search for help from the web, to consult this very interesting forum.
                              So I decided to sign up and I intend to participate actively by making available my knowledge and experience on the subject, I'm a new user but at the same time I'm old in the sense that I have 4 decades of experience in repairing and designing electronics but above all I'm a great passionate about the subject.

                              Having said that I come to the gist of my post on the forum as the title suggests.
                              For my passion for technology I'm now collecting several...

                              Good day,

                              I have tried to remove BIOS supervisor password from Panasonic Toughbook CF-33 mk1. Model number CF-33AENABTG, unfortunately I don't have any other info.

                              I read the BIOS using afuwin, edited it and tried to flash new edited BIOS using afuwin. Unsuccessfully. Afuwin showed "Error: Problem erasing flash." starting with 0x00040000 and stoped. Then I tried many other options to flash BIOS from Windows without any luck. Finally i rebooted the device - and no post. Afterwards I have read the corrupted bios chip (MX25L12873F) using EZP2010 programmer....
