    Replacing Capacitors on a Samsung LNS4696D power board

    I have read a couple threads and believe my issue is bad capacitors but I am not sure on what to get. The ones on the board are CapXon and these are the values:

    5 - 1000uf 10v GL 105C
    8 - 47uf 50v KM 105C
    5 - 10uf 50v KM 105C
    4 - 1000uf 25v KM 105C

    If there is more info needed let me know.

    Thanks for the assistance

    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...

    Upgrading a Samsung ue55nu7096u with logic board from an ue55ru7105k -- good idea?
    by ohren
    I hope this is the right forum to post in despite not technically being a repair, but still a question of swapping boards.

    I thought I'd explore the possibility to upgrade an existing working Samsung ue55nu7096u with the logic board (and power board if needed) of a newer model (ue55ru7105k) of the same size and appearance (and resolution). The reason being I'd like the extra inputs of that board including component in, an extra HDMI port and bluetooth. Its panel is broken so I have no use for the board otherwise.

    The models launched in 2018 and 2019 respectively....

    Samsung LN46C630K1F – Intermittent Backlight, BN44-00341B Power Board

    Summary for TL-DR readers:
    • Backlight is intermittent, may come on with TV boot or not. No flickering, never fails during TV on.
    • Have obtained Samsung schematic & service documents - Can upload if helpful.
    • Have read ALL applicable threads
    • C1818 and CP820 replaced as low hanging fruit
    • CN802 data taken for normal and failed BL operation. SUMMARY: Pin 2 - 5vDet = 3.52 @normal, 0.0 @BL fail. Pin 6 - EPWM = 1.631 @normal, 1.058 @BL fail.
    • VCC pin (18) of PFC...

    what to check before replacing hybrid MOSFET/controller IC on SAMSUNG TV power board
    by MacGyver's paperclip
    TLDNR; Have an old SAMSUNG TV with blown hybrid MOSFET/controller IC on power board to be replaced; replaced blown main capacitor on same power board several years ago successfully, and TV has been working fine since until this IC popped all of a sudden. Want to know what if anything to check on board to make sure before replacing and testing with new IC. Have 2 new matching ICs, DIP socket to make removal/replacement easier, a whole other known-good power board with which to compare, if necessary.
