    TX-55DX600B one (1) blink SOS code

    Hello,
    I have a TX-55DX600B bought 16 months ago from Panasonic outlet on Ebay, seemed cheap at the time. Worked well up until now I have the following issue;

    Turn on.
    green light flashes quickly for maybe 3 seconds.
    then screen flashes (can only see if back cover is off, or if in dark room.
    Red light continues to flash every 3-4s.

    I believe one blink code.

    I checked for short on PDU - P board with meter from fuse (which received V) to ground and none - is this correct?
    I have ordered an A board, coming this week (can return at cost of postage).
    If its not the A board - I believe it is relating to Backlight LED - BL_SOS (LED driver).

    Question - Am I correct in my assumptions - I got info from this forum and also;

    If not A board, should I try P? or is this likely to be LED strip - in which case is it worth bothering, simple enough for a normal person to manage? I guess I'd need suction cups and two sets of hands.

    Attached are images of back of board.

    Any help / advice appreciated, Would really love the SM for one of these if someone has one.
    Thanks,
    Tom.

    Looks like the Backlights have failed.

      Thanks for the reply.
      Could I ask what makes you say that and also would you advise to attempt repair? All led’s or just the faulty strip?

      Thanks

        Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
        by Tynan Dill
        I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

        Upon bringing it home and plugging it up, it showed a standby light.

        I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

        The screen seems to blackout and stay black, but with a flashlight I can see the display.

        With my Playstation 4 connected via HDMI, and running a game I can hear sound.

        Assuming...

        LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
        by Hakuu
        Hi There,

        This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

        After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

        More Details

        TV Model - LG OLED77G1PUA

        Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt...

        Sony xbr-65x900c main board issues?
        by jb_Bak
        Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.

        Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:
        Power Board Connector that goes to Main board
        CN6401
        Pin 01 NC
        Pin 02 NC
        Pin 03 "BL_ON": 0V
        Pin 04 "N/C"
        Pin 05 "STBY 3.3V": 3.5V
        Pin 06 "GND": N/C
        Pin 07 "AC_OFF"...
