    Lg 42ld520

    Hello,

    My TV is fine once it heats up. But it has an issue that was a horizontal one fifth of the bottom of the screen at first. Then when I left it off for a week when I turned it back on the same issue was 98 percent of the screen with a little strip at the top where I could see my Computer Mouse move.

    I use my TV for a monitor and it has been mostly on for 3 and a half years.

    The lines actually go vertical inside of a horizontal problem.


    That bad percentage part of the screen becomes unresponsive while the good percentage part is fine.

    Also, it takes two times hitting the power button to get the TV to come on.

    Then the light which should be blue goes out. Even when the TV finally heats up and works the light goes out and stays out.


    Any idea what this issue is?

    I have one like this, The fault is on the main board around ic603,Possibly C653? I have not isolate the problem yet as the set started working again.
    When it acted up there was a good picture about one inch from the top and the rest was lines etc.
    If I find the exact component causing this issue I will post.

      Thanks RJ

      I still have the same issue but as long as the TV stays on it is fine and the screen shows fine.

      But now I have another problem.... whenever I am watching videos the power on the monitor just goes off for about 2 seconds and then comes back on and plays again only to do it again.

      It does it for hours and then stops and goes days without doing it only to start happening again.

      Does anyone have any idea about this LCD TV?

        MacBook Air A2337 (820-02016) USB-C Port Issue – Only Works in One Orientation (CC Line Problem?)
        by rounin
        Hi everyone,

        I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.

        🛠 Original Issue
        The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
        Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.

        I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

        Three 820-01700 32GB Logic Boards Same Issue: Won't Wake From Hibernate
        by ugamazing
        I have three identical-spec 820-01700 boards (2.6/32/512), and ALL THREE boards came to us with the same fault, from different sources: The boards don't wake from hibernation with the keyboard or lid, they ONLY wake when you press the power button. I understand this is a very minor issue, but the boards must be fixed!

        We will of course begin with the obvious (checking lid signals), but I couldn't help but notice these three boards were all 32GB variants. Has anyone noticed an issue relating to these 32GB boards in particular? I of course don't think it's a RAM issue, but it's bizarre...

        Hello guys!
        I have a strange issue with my laptop keyboard and I'm lost trying to detect what's wrong - the KB9028Q-C or the keyboard itself.
        It powers on OK and has no other issues except the following:
        • CAPS LOCK does not work at all
        • Fn button toggles Flight Mode
        • When I press 't' or '5', it produces 't5', and when I press 'y' or '6', it produces 'y6'
        • (with SHIFT pressed: 't%' and 'y^' respectively)
        I initially thought it was a keyboard malfunction (internal short, etc.),
        but when I press and hold...

        Alienware 15 R2 Service Tag: DL7NN32 ISSUE (Battery is not charging)
        by Simone Vergani
        Hello everyone,

        I'm experiencing an issue with my Alienware 15 R2 (Service Tag: DL7NN32). The laptop works perfectly when connected to the AC adapter — it powers on and functions normally. However, the battery does not charge. If I disconnect the DC adapter, the laptop shuts down immediately, as the battery is at 0%. I have replaced the battery with a new compatible one, but the issue persists. I also replaced the AC adapter with a compatible one, but the battery still doesn't charge.

        To assist with troubleshooting, I'm attaching two power circuit schematics:

        Dynabook Satellite Pro C50D-B-100 - BIOS Issue, Black Screen
        by wizard13
        Hello everyone,

        I am experiencing a BIOS-related issue with my Dynabook Satellite Pro C50D-B-100. When I power on the laptop, the screen stays black, and there is no response from the system. I suspect a corrupted BIOS.

        I have checked the forum and the available documentation but could not find a solution specific to my issue.
