    Panasonic tc-l32c22 lcd

    I have a Panasonic TC-L32C22 , which had no power. I bought and installed a new power supply. The set turned on and worked for about 10 minutes, turned it off and now will not work again

    I checked for 5v standby and it is 6v instead

    Any help would be appreciated please

    Thank you
    John

        There is no markings on the connector. How can I determine which is the ps-on? any ideas how I can find ps-on or, to further test this set? Belongs to my neighbor and I would love to look like a hero to the kids. they would be very happy if their tv was fixed. they do not have much at all

          How is the battery in your meter? Test a new AA battery - you should see around 1.5 to 1.6V.

            Changing the batteries in both meters right now because, I am getting 2 different readings from each meter even though both readings are within a volt in each. One is a Fluke 8060A true RMS multimeter and the other is an Atten AT9205C (chinese but, new and seems pretty good

              Also, bear in mind, I have 2 power supplies and, they are both acting the same. I replaced the power supply because I found one on Ebay for $20 and, it actually worked but, once I turned the power off to replace the cover thinking it was fixed, it would never turn back on.

                  Okay post a shot of the green (under) side of the PSU PCB. Clear, detailed, and close as possible to 2000x2000 pixels but not exceeding. If necessary, break it down into multiple shots.

                              Tom means the number that hopefully is on the IC with 20 legs that is ringed in red on the picture. You may need a magnifying glass and try rubbing it gently with isopropyl alcohol.
                              If it is the same as the tv number I apologise.

                                On the P2 Power board connector, the TV_SUB_ON (Power on from micro) is on pin 9, the Inverter On is pin 13. First, pin 9 should go to >3v to turn supply on, followed by the Inverter On pin.

                                  By the way, are you getting any blink codes on the Power LED? Or is the unit completely dead.

                                    if the tv worked with a new supply,but didnt when reassembled ,i would take the back off again and reseat all connector cables,(unplug and re-plug in),and making sure the psu ground points are grounded,and have a check and double check on the tv's side buttons.the little tact switches if jammed will cause this problem,if one jams on, the set will sense it and not respond to remote or the side buttons
                                    fixed so far...376 lg lcd tv's,24 onn tv;s,24 panasonic lcd,16 jvc lcd,12 marshall jcm800 amps,refurb of various disco equipment lighting,old style disco decks ,and a flymo!

                                        So, correct me if i am wrong. It looks as though the 115V goes to the fuse and then to the Rectifier, then to the 5V standby transistor so, if no 5V I should look to this transistor

                                        I think i will find a properly working power supply to determine

                                        I apologize IF i seem dumb but, I obviously am. I must be skipping some chapter or something because, I am surely missing something here


                                        Thank you for your help in trying

                                        I guess I will just need to study more to hopefully someday understand

                                          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 hereπŸ€”?
                                          Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting πŸ˜‚.

                                          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...

                                          helo everry body!!!
                                          My laptop HP 245 AMD 14-FP5-6L -GDDR5X2 has a battery charging circuit error:
                                          - If not power on, battery charge ok.
                                          - if i turn on the power, not charging the battery ( the battery charging indicator light, from yellow to white)
                                          The laptop only charges when not turned on. I have changed the battery and charger, but the situation remains unchanged.
                                          I replaced the BQ 25A charging IC but the device only charges when not turned on.
                                          everyone please help me with solution, what should i do ?
                                          thanks a lot !!!!!...

                                          Panasonic Toughbook CF-33 mk1 BIOS repair
                                          by aa10aa10
                                          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....
