    Citronic AC-1USB Output Too Loud
    by Carm99
    Hi
    I have a Citronic AC-1USB.
    When I run a turntable into it and then try to record it. The volume is too loud and distorting. In the red. Mainly 12” Singles. I haven’t tried a CD into it yet. I’m wondering if there is any way to bring the volume down inside the unit itself. Change a part or two. Put a small pot somewhere as there are no adjustments at all in there. I’m looking for the schematic but not found one yet.
    Heres the circuit board inside.
    Cheers

    faulty loudspeaker amplifier-no sound output
    by Cornboats
    I've several amplifiers of different sizes which are faulty. I haven't fixed them because I haven't a clue. This is the smallest culprit. 240v in (UK) and 12v dc to the board. Small neon lights when power button is on. Different dc voltages across all of the capacitors. Where do I go from here?

    Blown capacitor repair on MSI Radeon RX 5700 XT MECH OC
    by MeetingIncapable
    Hello,

    I am new to repairing computer electronics, so excuse any mistakes I make.

    A friend of mine had a broken graphics card (MSI Radeon RX 5700 XT MECH OC) and gave it to me. It does not power on or show any signs of life.
    I identified what looks like the remains of a blown capacitor at the bottom of the board (see picture).

    I wanted to replace the capacitor, but I have two questions:[LIST][*]Does this repair have a chance of working? or is a blown capacitor a sign something else is wrong?[*]How do I determine the rating/value of this capacitor?...

    BIOS - DELL INSPIRON 15 7559 - Need the CLEAR ME!
    by joaopedrogallo
    Hi there! (I hope i'm doing the right way to ask this)

    I'm working on a Dell INSPIRON 15 7559, with service tag CZ4X2J2.
    Im sending both BIOS and EC .bin file and ask if someone can Clear ME it for me.

    I guess it's only BIOS to be cleared, but I'm sending both.

    It's taking too long to show the DELL logo.
    I took this files from another original Dell motherboard which stopped working.

    Best regards!
    Thank you in advance!...

    Main rail / charging circuit issues on Bucky/BenSolo 17859-1 board from Dell Vostro 5581
    by benwaterson
    Hi All

    Been a while since I have been here, and a bit rusty.

    I have the above laptop motherboard that was working and now the charging circuit is faulty.

    Have 19v in fine until it hits PU4403 - not shorts I can see and thermal cam reveals nothing.

    I have swapped out the ISL9538 and also the two mosfets (PU4403 and PU4405). Have 2.8v at the power switch, which pulls low when pressed - charging light comes on and goes straight off

    Below are measurements (pin names are per the datasheet for the ISL95338 (couldn't find one for ISL9538,...

    PS5 EDM-020 Beep but no light or fan spin
    by CPRMatt
    I have a PS5 in my shop that beeps when the power button is pressed but the light does not turn on and the fan doesn’t move at all. I tried replacing the power supply because it had some roach bodies in it but the rest of the device had no signs of infestation, and it does the exact same thing. Then I tried replacing the HDMI chip (MN864739) because I saw somewhere that it could be the culprit but still no change. Does anyone have any other suggestions or things I should test on the board or is it likely dead? Thanks!
