    Panasonic TX-P42VT30E 7 blinks of death

    Hi,...

    I am just triying to fix this Panasonic. I will tell what I have done until now.

    I have checked the SN BOARD and I found some Transistors shorted and I changed them all.

    At the same time I saw that the PSU is also broken as it blows the T4AH250V FUSE. So I will have to change the 2 R6015ANX MOSFETs, so I need to buy them on internet because here I could not find them

    I am confused about fixing this Panasonic. What I know is that the SN BOARD is not in Shorted if I check the main source connector. I also checked all the connectors to the screen but are all ok.


    I am a novice and not professional for that reason I am looking forward to hearing some advices from all of you.



    What do you recommend to do? First, I need to wait the 2xR6015ANX.

            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 😂.

            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...

            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 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,...

            Looking for assistance troubleshooting a Panasonic TC-P65ZT60 with 3 LED Fast Blinks
            by CrewmanRedShirt
            Hello all,
            As the title states, I followed the troubleshooting guide located here: https://www.manualslib.com/manual/23...page=53#manual, which concluded the 'A' board needs to be replaced. Looking around the net and eBay, I see that there are repair services for the board (TNPH1043UE? Not sure if it is a 'UE' as the suffix grid does not appear marked). What additional troubleshooting can be performed to ensure 1) this board is the problem and 2) since there are repair services, what are they fixing on the board?) I expected 3.3V not to be available anywhere...
