    Re: Haier Power Supply Board AY090D-4SF01

    Alright, well, I went back and rechecked the LED strips (individually this time), and one strip had a bad (but working) LED....8vdc dropped across it. I didn't notice it the first time around cause the whole array worked.

    So thank you all for your help, I did learn alot about the power board circuitry which will be helpful in the future!

        Glad you found the culprit, was a good refresher thread for me too, was able to put that backlight testing back into my memory, it fell out, hope it stays in longer this time.

            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.

            Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
            Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

            by Soulzink
            Hi everyone,

            I am trying to fix a samsung washinmachine power supply main board.
            I already replaced it with another one to fix the machine but i want to try understand the issue with the old board.
            Therefore i hope to be able to get some help to explain what to check in order to troubleshoot.
            The power supply board reference is the following: DC41-00189a
            I have followed one thread (https://www.badcaps.net/forum/troubl...ingmachine-rel...

            Samsung Power Supply Board BN44-00874F
            by Nicktronic
            Hey everyone,

            This power supply board is hard to find but there are repair kits available. This board had a blown fuse, FP801S, blown PFC MOSFET, QP802CS and ceramic cap, CP809. I replaced them with parts I already had and tested the rest of the parts that would've come in the repair kit and they were fine. I powered the board up on the bench expecting, in typical Samsung power supply board fashion, to see all my output voltages but, nothing. 0 volts on CNL801, CNM801 and CNT801. The only thing I have is 170vdc on the filter caps. No standby voltage either.

            Anybody...
