    Lenovo Thinkpad Yoga X1 Gen 6 no charging
    by Andreasbest
    Hello.
    I received a yoga 6th gen ( nm-d341 ) that is not charging, tried both charging and thuderbolt ports but no charge, i don't see any physical damage on them, in fact they look like new.
    When i use charged battery works great, i updated to latest bios as i saw a warning from lenovo regarding urgent update to fix charge problems and also updated ME firmware, no luck.
    What do you suggest?

    ASUS UX363JA No power
    by dclass-pro
    Hi guys, I'm repairing a motherboard from an ASUS UX363JA R2.2 that won't turn on, I found a component exploded near the display connector.
    I don't have the diagram so I can't figure out what code it has, also if I power the main with the USB-C I have a draw of about 2A at 5V and it doesn't go to 20V.
    I checked the mosfets and inductors and everything seems ok, but I don't know what to do.
    Do you have any ideas?​

    LG OLED55CX Clicking No Power
    by cheebster
    Hello, i have this OLED here, as the topic says OLED65CX.

    TV shows standby led, when pressed the PSU clicks, then shut down.

    Disconnecting the 12V VIN from the T-Con, make the TV boot up, led flashes like normal and it stays on.

    What i've tried so far:

    I have a working TV, an OLED55C1. Similar TV... Took all the boards to the C1, 1 by one, and everything works. So basically, all of these boards from the defective CX (PSU, Main, TCON) works either 1 by 1, or together on the working C1.

    However, none of the C1 boards work on the CX,...

    MOSFET no voltage at gate Quanta G7HA DAG7HAMB8EO
    by irfan karatela
    I'm working on a HP Pavilion Laptop Model 15-eh1508sa that is missing 19v. I've looked at the schematics and want to know what conditions the ISL9238C checks before it enables the gate for MOSFETs PQ8200 and PQ8201,

    I havent found any shorts on the board.

    I get 19v at +PRWSRC but around 1.7v at the Drain of PQ8201(+vin)

    NV-V8000 vcr caps change
    by Thermaltake
    Hi, I am restoring my NV-V8000, and wondering there is 16V 4700uF cap near transformer, is it low esr one or normal one ? On PSU they are all replaced with low esr, but I am not sure about that one near transformer. I tried to google and look at manual but I couldn't find anything.
