    LG PDP50X300 6709900020A power supply clicks on and then off

    So...do a search,take a look on YouTube this is a common problem. There are 9 capacitors offered on Ebay to repair this board when the capacitors are showing signs of bulging. Some show the board with the capacitors in fine looking shape .
    Unfortunately there are no posts or when a YouTube tutorial is given show the end result that this does solve the problem or does it? I have searched and searched, but no results about the end result.
    Does any one have experience with this board ?

    I understand 1: Capacitors discolored or bulging
    The next are to see if there is a short or loading of the next boards
    2: Disconnect the Y-sustain board, the large board to the left, it also powers the Z -sustain board, the large board to the right.
    3: Disconnect the other connectors one at at a time 3 in total
    .
    Always remove the power cord from the tv each time to reduce the hazard of a shock, do not remove connectors while powered to reduce the chance of shock to yourself or the boards...right!
    This is a 2006 model from what i have read, with older models the power supply does shut down if you remove the connectors.

    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.

    Panasonic switching power supply daughter board has two 27uf @ 50 volt capacitors which I do not keep in stock
    by sam_sam_sam
    I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow

    This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

    After all of...

    HP Pavilion 15-eh Board DAG7HAMB8F0 - CPU throttling to 0.4GHz (PROCHOT_EXT) and black screen
    by m1ch43lzm
    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...

    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...
