        These things are built like overbuilt tanks, I don't think so. The IR (remote) sensor should be separate from the buttons, you could unplug the buttons and try without them.
        Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
        For service manual, schematic, boardview (board view), datasheet, cad - use our search.

                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...

                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...

                Panasonic Plasma TH-50PZ85U No screen No blinks on red power light
                by Alicat
                Hello,

                Stopped by this site trying to fix my parents Panasonic Plasma TV.

                Model number is TH-50PZ85U

                Power comes on and the red power light stays on solid.

                Did a few checks like hold the power button on for 60 seconds, hold the - Volume while holding the menu button, no luck, still@ blank grey screen as the screen lights up very vague.

                I also hear a few clicks.

                I also think my parents said there was a thunderstorm and the TV failed after that.

                Section 6 in the service manual talks about power and no screen,...

                Panasonic P42S30 Plasma - Pink sparkles
                by Lintesir
                My parents' Panasonic P42S30 died recently, and they asked me to have a look at it. I was able to identify the SN-board as the culprit, as it was shorted. After removing Q401, Q402, Q421 and Q422 the short was gone, so I replaced these components and that got the TV working again. However, when testing the tv a bit, I noticed quite bad pinkish sparkles on some colors. For instance the greyish bar on this forum seems to trigger it quite badly. I made a fullscreen test picture with only that color, with the below result.

                There is about a 5cm high region at the top without any sparkles,...

                PANASONIC TX-P42X10Y Plasma TV damaged after a power spike
                by tofik
                Hello, I have an PANASONIC TX-P42X10Y Plasma TV, purchased new in 2009.
                Unfortunately plasma is not working at all after a power spike. Standby LED is not even working.

                I did some quick tests, YSUS + ZSUS MOSFETS and IGBT's are free from shorts, diodes on these modules seems to also be fine, buffer board is free from shorts as well.

                Anyway I focused mainly on the PSU, did some voltage tests with the results as below, I attached them on the photo (also please see attached PDF with the SERVICE MANUAL for this model, page number 43).

                I understand...
