    Seeking boardview & schematic if possible for the machine mentioned in the title.

    HP Vetius 15-fb0048ax / DAG3PPMB8D0 ( REV: D)

    I've checked other similar units listed here on BadCaps but they're notably different unfortunately.

    Problem with Samsung Tv UE49MU6120KXZT (Version 01)
    by RGSound
    Good morning I have a problem with my [B]Samsung UE49MU6120KXZT (Version 01)[/B] TV with Motherboard[B] BN94-12644A[/B].

    After disconnection from 220V the TV remains switched off with status led off. I need information on how to proceed with reprogramming the flash memory and the BIN file to reprogram it.

    I have purchased this programmer on Ebay: [B]CH341A EEPROM PROGRAMMER FLASH BIOS 24 25 SERIES + CLIP TEST[/B]. I include photos of the motherboard. I am not very experienced but I would like to learn so the more detailed the information, the better it will be for me...

    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

    PP5V_G3S is missing too

    Someone has the power on sequence of this ?

    Thank you on advance.

    SMPS 750W 25VAC out not working correctly
    by foshland
    Hi, I have a power supply that now is working but generating a lot of heat (200ºC) in the resistors circled by green (see photos) with a minimal load (60W). Output voltage is correct with that minimal load. What cai I look now?


    Thanks a lot

    HP adapter for Dell monitor
    by paparazzo79
    Hi guys.
    I got myself used Dell 27" touch monitor but I got scammed again, seller sent HP adapter.
    Though voltages are the same, I suppose power supply design is not the same.
    So may I use it without any harm to the monitor?...
