    Lg 42pt350-ud

    I don't know how to exactly label this but upon cutting on tv the panel initializes for a brief 3-5secs and then goes off but the TV remains on till you cut it off. All the voltages are present.
    The only one that changes is ER on the Z-SUS which starts at 20 in the first 3-5secs but then after the panel goes off jumps to 60-70..or it may be the opposite.

    Could anyone guide me on this repair?
    Of course now that I have wrote that last sentence about ER I am thinking it may be the Z-SUS.

    Have you tried using the EXT AUTO GEN to isolate the main board? If you need help, post a picture of your control board.
    Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

      I am not familiar with using that.

      So, here are the ctrl board and main.

        LG Plasma ZSUS Flashing Screen, No Booting! - 50PB690V
        by reessi
        Replaced Zsus beginning of year as most transistors were short stopping tv powering up.

        Now screen flashes on off continually and ZSUS ticks. Looking like replacement maybe faulty or could something else cause it to shut down.

        If I remove both tabs from ZSUS to screen but keep all other connectors to ZSUS on then TV boots properly but screen very dark without ZSUS output, no ticking from ZSUS. So it only shuts down when under load from screen.

        If it is ZSUS then how to fault find, I already looked for shorts. No transistors shorted or caps and its...

        All Voltages are OK except ZSUS 15v.
        YSUS board disconnected still 15v missing.
        ZSUS was replaced: 15v missing.
        Any help will be appreciated...

        plasma TV Lg 42w451 - why is the zsus igbts damaged when the ysus is plugged?
        by Salvatore057
        Hi all,
        I am trying to fix my plasma TV which is not powering on due to damaged IGBTs. I have changed two igbts and 2 IC drivers on the zsus and also two igbts on the ysus.
        Now everytime I plugged the ZSUS and the YSUS boards to the power board, the two 30f124 IGBT on the ZSUS are damaged and the TV stays in standby mode. When I plug the ZSUS board alone the TV turns ON but I do not see pictures. When I plug the ZSUS board without the two 30f124 IGBTs and the YSUS board, the TV powers on with a picture.
        I am lost, should I change the YSUS board? Is the YSUS board damaging...

        LG 60PB6650 - Bad ZSUS (3.8v to YSUS instead of 16v)?
        by JDC
        Make and Model: LG 60PB6650-UA
        Issue: Turns on, no backlight, can hear static (no channel)

        I've been repairing TVs for a couple years now. I know how to use a multimeter for the most part and know how to test most components for shorts.

        The power board connects to the ZSUS and then connects to the YSUS. The ZSUS is where I believe the failure is because the 16v line is only 3.8V, even when I disconnect the ZSUS from the YSUS.

        This particular model seems to have a common failure with its YSUS. My goal earlier was to prove the YSUS was bad so I could...

        LG 60PZ570 - Zsus replaced, still have issues
        by JarrodHook
        Hi everyone,

        I have had a interest in electronics forever, and as a hobby have tinkered with repairing things, taking them to bits, and so forth.

        However, I have a LG 60PZ570 that is causing me to rethink my life!!

        I purchased it for $100 as it had no picture, got it home, and it has the classic ZSUS issue, where in the picture is splotchy and dark.

        I checked the ZSUS board and determined there were a few blown transistors, fuses, etc.

        I looked up the repair kits, but the $70 shipping fee was a bit steep for me (I live in New Zealand)...
