    Panasonic Viera TH-P42X20A Power Issue

    Hi guys, I have come across this set which will not fire up. No physical damage to PDP.

    I replaced the SMPS (LSEP1287AN), but the symptoms were identical.

    When 240v supplied:

    Three clicks in quick succession from SMPS
    Flashing green LED on front bottom centre for about 4 seconds
    One click from SMPS
    Red LED once on front bottom centre, pause, repeat red LED (continues)

    What I did then:

    Isolated every cable to every board one at a time. None made any difference EXCEPT P6 (on SMPS) to A6 (on MAIN). When this is removed, and 240v supplied:

    Three clicks in quick succession from SMPS
    NO green LED, just a very short pause
    One click from SMPS
    Red LED x 10 on front bottom centre, pause, repeat 10 x red LED (continues)

    Please note that it makes no difference to any of the above by changing the position of the manual on/off switch. Known working remote has no effect on anything at all.

    So I'm guessing a have a component failure on the MAIN? Any help would be deeply appreciated.

    Cheers.

          Looking for help diagnosing a 65" Panasonic Viera TV - TH-65DX700Z (Turns on - Clicks - Turns off)
          by mostachio
          Hi Badcaps,

          I've had a friend discard a TH-65DX700Z Pansonic Viera Television and I've decided to have a go at repairing it. If possible could I please get some advice in terms of diagnosing the problem so I can purchase the appropriate parts for repair whether it be components, a repair kit or a replacement board. I am happy to post pictures if required.

          TV Details:

          Symptoms:

          The television turns on and displays a picture then makes a clicking sound and turns off.

          I haven't opened it up yet but...

          Panasonic Viera LC470EUN (SE)(M2) T-Con issue?
          by Ama Chur
          After watching some youtube videos and checking some forums, I'm at a loss. With both ribbon cables connected, we have no image. With the left one pulled out, the screen is black and white, split down the middle. With the right cable removed, it is all black. Backlight is working fine and we have sound and can open applications. We are strapped for money right now and are hoping to repair whatever the issue may be. I think the TV was manufactured in 2012, so I'm aware that may not be possible. Edit: Found a single vertical line of blue pixels on the left side of the screen with one of the ribbon...

          Dead Panasonic Viera TX-P65STW50 Plasma TV
          by badcappo
          Hello, got a ST50 plasma TV for repair. No signs of life, not even blink codes. Opened it up to check the power supply, type MPF6914. Apparent issues from visual detection and measuring for shorts:
          Diode type G972s6 - D101 with a short
          Mosfet 06N90E - Q301 shorted
          Fuse T5AH 250V - F103 blown
          Diode D301 shorted
          Relay DG1U-17VDC II - RL001 blown

          I have not found a circuit diagram. Maybe someone here already dealt with a similar issue? Thanks for tips where else to check πŸ˜€...

          Panasonic Viera TX-L50E6E - no image
          by J8rda7
          Hi,
          the TV has a black screen. Sound OK, backlight OK.

          When I measure T-CON voltages, there is VGL+VGH=0V. After unplug the right side of the screen from the T-con, voltages are OK and half screen works normally.

          I tried to search for any kind of short on the right side, but I had no luck. I have a beginner experience in measuring and repairs of the LCD panels..

          Thanks to anyone who can guide me in solving the problem.. and be patient with my english πŸ™‚πŸ˜

          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 hereπŸ€”?
          Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting πŸ˜‚.
