    Panasonic TH-P50G10A 7 blinks (something different)

    Got this Panasonic TH-P50G10A 7 blinks.

    Typically you'd be expecting SC board and I was not disappointed there.

    But this is not your typical blown SC. Essentially it's not shorted or none of the IGBTs are.

    I found the VSCN voltage was a bit weird, so I did what i hate doing and disabled the SOS7 cct.

    Turn it on, no bangs , no smoke , perfect picture.

    Now take another reading Vscn to chassis is reading 14-15V, -40V is expected and to VAD it's about 200V expected 145V. So a difference of 55V.

    can't work it out , have probed and swapped over almost the entire Vscn gen cct.

    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 😂.

    TV Model: Panasonic TC-P55ST50

    Panasonic Plasma 42PV80LB 7 Blinks, VSCN too high
    by Biruslapio
    Hello I'm struggling with this old plasma TV and its SC board, TNPA4393, I've measured the SU/SD buffers, every IGBT and transistors, gate drivers, SMD diodes, optocouplers etc, no shorts or suspecting measurings, at least with they soldered on the board.

    VSUS - 187V
    VDA - 75V
    VE - 130V
    VSET - 320V
    VAD - (-149V)
    16V_F
    5V_F A/B
    15V

    All voltages are normal except for VSCN, which according to the service manual is supposed to be 145V+-4V, it is always 205V.
    VSCN voltage is fixed, generated and measured from VAD...

    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,...
