    Asus E410 only works on battery after reverse polarity
    by Kervin Mathumbu
    Hi everyone. Fixed my AC and despite trying to be extra careful, I reversed polarity and got a notable pop sound. Now the PC will only work on battery. Windows still shows the battery as charging but the count actually goes down until empty (I have two of the same laptops).

    I have board R3.0 so the schematics on another thread here do not match mine. I have tested the BQ charge IC and my pin 1, 2 and 3 have 3.35v each - instead of 18v or 19v. Could this be a bad BQ IC or capacitor? Any thoughtful advise sould be greatly appreciated.

    Sony Bravia KD-50X690E blown resistor
    by x_orange90_x
    I just picked up this tv yesterday and the previous owner said while watching tv he heard a loud a pop and then the screen went dark. I removed the back cover and found the source rather quickly; resistor R8601. A chunk of the ceramic had blown off exposing the inner wire. Due to the damage I cannot make out the colors of a couple bands. I likewise cannot find a datasheet for the power supply. I tried pulling up pictures of the same board online but the resistors have different colored bands which I half expected as I've had this happen before.

    The power supply is 715G8413-P01-001-0H2S...

    Xbox One X Psu
    by Viktor Árvai
    Hi I have a question about an xbox on x psu model1815 rev1 , Every time i plug it in it trips the housebreaker and the fuse inside. On the high voltage side almost everything is shorted to ground , on the 12 v side no short on main leads and nothing in general.
    My question is what is the most common part that can cause this, i figured ill try it here first before i start pulling off everything.
    Thank you!

    A1708 peculiar bms problem.
    by 100FIX
    Hi, I have a mbp a1708 2017 that I am trying to fix.

    (1.) It turns on fine on ac power when bms flex is unplugged.

    (2.) I noticed when battery & charger is unplugged and reconnected, it turns on only after a few minutes but doesn't stay on battery power i.e. it turns off as soon as charger is unplugged and doesn't turn on until (2.) is repeated. During this time, health information and charging information are displayed and normal and battery charges but laptop turns off as soon as charger is disconnected.

    I have reballed u7000, problem persists.

    No option for optical audio output on older Samsung LCD LN52A650A1FXZA
    by ohmmy
    Im trying to use a soundbar with it. Plugged in the optical cable on both ends but in settings of the TV the “sound select” option is greyed out and won't let me switch off “main” even if I turn off “TV Speaker” option. Anyone have an idea on why or what I need to do? Thanks...
