    Newbie needs help identifying bad cap and value

    Philips 42PFL7422D/37 LCD 42" TV. No display but I see a picture when I use a flashlight at an angle.

    I'm a newbie. This post led me to this forum:
    https://www.badcaps.net/forum/showth...2PFL7422D%2F37

    From searching this forum, I believe I narrowed it down to the inverter board. Please can someone tell me if the cap on the left in the picture looks bad and how do I determine it? Don't have a ESR meter but got a multimeter.(again, I got this from reading through some posts).
    Am I on the right track to fixing the problem?
    Also, what value is it if I were to go buy one at the store? I have some soldiering experience. Can't do chips but caps, resistors, transistors are no problem. Thanks so much for everyone's help.

    Those caps are definitely bad. Both are bloated and the one on the left is leaking.

    You are going to have to remove them and read the uF and voltage value because they are probably hidden by the white glue or on the underside.

    PS. Post pictures to this forum using the manage attachments as per (but not inline as they slow down loading of pages)

    Once you find the values, post them here and tell us where you live so we can suggest proper caps and a vendor in your area.

      There. Did it for you.

      The new forum format lets you upload from a URL, but not be linked to the remote site, so the picture becomes a part of badcaps.net.

        Need Help Identifying Parts on a crossover and a few other newbie questions
        by UL161
        Hi I am trying to refurbish this crossover with some higher quality poly-caps/parts... The speaker is a in-wall Polk 65-RT... Key questions I have are:

        1) What in the world is the yellow part on the board (label is MET 1.0J 100V)?... Should I even consider replacing it?
        2) The 470uF cap.... Does anyone know have a suggestion as to where I can find a reasonable audio quality polycap near that value? (or at least 3 160s or the like?) { I don't want to spend $70 just to replace this one if I can) (maybe even someone looking at this circuit could even tell if this cap is important...

        Good morning, I would appreciate help identifying resistors responsible probably for volume down / volume up buttons that I accidently knocked off while replacing fan connector. I enclose picture with location. Thank you for help in advance.

        Help Identifying IC on MacBooks Pro - 820-02020

        Subject: Help Identifying IC on 820-02020 (MacBook Pro A2338 M1, 2020) — C02045500 / EKQ8LL1A


        Hi all,


        I'm working on a MacBook Pro A2338 M1 (2020) with logic board 820-02020.

        The machine has a power issue — not powering on, and I'm trying to trace the fault.


        While inspecting the board, I found a cluster of components


        This area looks damaged or burned — there are about 4–5 components that seem affected


        I've attached a close-up photo of the chip and its surrounding area (see...

        70mai Dash Cam A510 - help identifying connector on camera module
        by m1ch43lzm
        Hi everyone
        I have a 70mai Dash Cam A510 which failed after about 3 months of being installed in my car, likely due to heat, i got it from aliexpress so no point in trying to return it for warranty (and shipping it back would cost me almost the same as a new one from ali)
        The camera would boot loop showing 70mai logo on the screen, sometimes it would boot fine then the live view would freeze or display purple lines

        I already took it apart, and found out that the camera boots fine if i unplug the camera module from the main PCB, sometimes "playing" with the connector...
