    Tom,

    I can get a guaranteed working Logic Board for under $20. Is it worth swapping it out?

      I cannot think of any obvious checks you can do besides checks for resistance. A logic board may be the best way to go.

        Which resistors would I test if I wanted to do that first? I have the service manual for the TV.

          Tom,

          I got the new Logic board and swapped it out. It definitely is better, however i now have a pink band on the left hand side of the screen. Can you tell me what that would indicate.

          Thanks,

          Dwight

            One of the ribbon cables on the logic board is not properly seated. Remove them and check carefully.

              Tom,

              The problem seemed to fix itself. The band is gone and the TV is working great. Thanks again for all your help.

              You can close another success story thread.

              Regards,

              Dwight

                Phillips 50PF7321D/37 Plasma slow reboot
                by Uranium-235
                Customer said if he keeps it on for a long time, turns it off, and later back on, it takes 10 minutes to get to proper brightness. Is this just a cap issue? I didn't have time to take it apart I was just there to drop a repaired laptop off

                Hello,
                I am having Samsung PS51E550 Plasma TV. While the TV was working, a crackling sound heard & video went off with audio still ON. After switching it off & ON, the red LED on TV blinks six times & then off.
                Opened TV cover & observed foll
                a) Green LED on the small PCB blinks at @5-6sec ON & off for 3-4 secs. Red LED on logic board ON
                b)Vs & Va on power supply board raises momentarily to 209v & 58v resp & then drops.
                c) Cold test on Y-main board shows all 3 pins of FGPF4536 IGBT short to Grnd.
                How to confirm Y -Buffer board...

                Panasonic plasma TX-P42ST50 - 6 blinks
                by jm1234
                Hi,
                anyone able to provide the service manual for old plasma Panasonic TX-P42ST50E?
                It turns off almost immediately (0~5 seconds after pressing the on/off button) and starts flashing the red diode 6 times.
                I disconnected the left-hand side board (SC?, both the ribbon cable and the power cable to it) and also another ribbon going to bottom left board. Then the led signal is 8 flashes. According to service guide to another Panasonic plasma it would mean the left-hand side board is faulty. But I'm not sure it 100% applies to my model.
                I checked that board for any obvious faults...

                What parts can be salvaged from a plasma with a damaged display panel?
                by SurrealMustard
                I recently found myself the proud owner of a later-model Samsung plasma (the PN59D7000 for those keeping score at home) whose panel was, unfortunately, damaged in transport. I'm now preparing to part it out, but am curious as to whether or not any damage would have come to any of the components by attempting to power it up with the panel being broken. I read in one Avsforum thread (for whatever that's worth 😂) that the "scan driver boards" (by which I assume he means buffer boards) could be impacted by doing so. Is that actually the case? If so, since I don't intend on selling bad...
