      Re: 4720z adaptor blink

      boodey,

      normally if the adapter blinks, it can sense a short in the mobo. capacitor, transistor or any other mobo parts that make the power adapter blinks.
      what i do if i cannot locate it with a DM, i remove the suspected part and put the charger on. if the blinks go away then, check the isolated part and compare it with other part of the same part number with your DM. (sometimes a mobo can have more than one part of the same part number.)

      i usually start the far end parts away from the DC jack. you can also try touching the parts for overheating. one way to find failed components.

      hope this helps

                  Panasonic ZT60 plasma tv with strange behavior and 8 blink code
                  by cloo
                  I recently got my hands on a 60" Panasonic P60ZT60 plasma tv (european model) that has some strange issues along with an 8 blink code.
                  It know this tv is getting old but it was once considered one of the best plasmas ever made, and i think it is still holds on to that even by todays standards.


                  So, long story short. When i first got the tv it had a very bright washed out picture with very raised blacks in all picture modes and i couldn't find the cause in the picture setting menus.
                  After doing a factory reset this problem was gone and the picture was back to...

                  Un50cu7000 2 blink oddity *partially solved
                  by EazyBone
                  I write this to maybe help another with this TV.

                  So I aquired this TV a 2023 model. It started the 2 blink reboot problem which indicates bad panel. It was still under warranty and the repair man came by.

                  The Samsung repairman brought a brand new panel and switched my original boards to the new panel. The new panel then had the 2 blink error code. The repair guy said he has seen this and the MAIN board on this model will cause the 2 blink. He then replaced the main/power board (they are both connected) and put it back onto my original panel. Voila it worked.

                  panasonic TX-P50V10E 6 blink led problem
                  by Vebririon
                  Hi everyone,

                  I'm new here and trying to repair my Panasonic TX-P50V10E plasma TV, which is currently showing the 6 red blink error code.

                  Just for context: I'm used to building PCs and installing modchips in old consoles, but this is my first time trying to fix a TV. I'm French, and while my English is okay, I'm using ChatGPT to help translate and clarify my messages as much as possible — so please forgive any odd phrasing.

                  I'm also not very experienced with using a multimeter, but I'm very motivated and ready to follow instructions carefully and report...

                  Panasonic P58V11B 8 and 12 blinks error "fix"
                  by Biruslapio
                  Bought this TV used not working, panel flashed briefly on power up and it was blinking 8 times, a quick look on SS board revealed a common fault on the 3uF 250V capacitors, C201 to C205 (C1620X in the service manual), the solder joints were all cracked, C201 and C205 pins were darkened and some sparking had occurred on them, C201 was split open and clearly overheated in its last hours, replaced that one and resoldered the others, 8 blinks fixed.

                  Also the previous owner broke the antenna connector by taking the TV out of the wall mount forgetting to unplug it, I desoldered the tuner...
