    Samsung QE50Q60TAU - Horizontal screen lines
    by Runlinc
    Hi everyone, the tv was in a continuous reboot cycle. To get the best screen image i can I taped the VGH and VSS pins on the left side buffer board joining ribbon.

    I am left with a good image apart from the black horizontal lines that I cannot get rid of.

    I cannot find anything on the buffer boards that has shorted.

    Do you think there is anything i can do to eliminate the lines, or are they caused by an internal panel short and the image cannot be impoved.

    Many thanks for your assistance

    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

    RAZER BLADE 15 2021 MODEL, No power, shorted rails.
    by chickenhawk88
    The laptop I am working on is RAZER BLADE 15 , RZ09-0369, the motherboard is DA560 VER 4.0. The original fault was it powered up with keyboard rgb on and no video on screen/hdmi. I found corrosion on memory module that leaked onto the memory socket. I cleaned the memory socket and was able to boot normal with other memory socket with good memory. I really should have stopped at this point as everything was working except for the one bad memory slot.

    I wanted to find out what was wrong with the other memory slot. I replaced a 330uf cap, a buck converter on back of board and when i...

    Biomass Boiler not driving cleaner motor relay. ENERTRES BIOMASA BI-650
    by edugimeno
    Hi everyone!
    I have this board that suddenly stopped supplying power to an output that drives an interchanger cleaner motor.
    I checked while the board was in place with all wires attached and there's no AC voltage on the corresponding plug X5
    This X5 is driven by fuse F8 (tested OK) which comes from the second orange relay
    To make sure there are no charcoaled contacts inside the relay, I got a 24VDC power supply and got it ready to manually power up the coil side of these relays.
    I respected the polarity, positive to cathode of protecting diode
    So provided all...

    MBP 2019 16" (A2141) LCD went out.
    by Ajm121
    Hey Friends,
    I have an MBP 2019 16" (A2141), i9/64Gb/1Tb, and recently the LCD went out. Not flexgate or Dustgate. Backlight is on and works, the board still works and posts to an external monitor. Not a software issue, absolutely nothing shows up onscreen except for backlight glow. opened the bottom cover and resistor L8504, a 120 ohm resistor (I believe) is fried, and fell off the mobo with a gentle touch. after it fell off, same problem with zero change observed which is why I think it is the issue. That resistor, acc to the 820-01700 motherboard schematic, goes straight to pin 46...

    Battery not charging in ASUS G532LWS Motherboard -> BQ24780S
    by cope
    Hi everyone,

    I have been working on a no power issue with my personal ASUS gaming laptop. It went dead a few months ago.

    Some history:

    Since then, I've found a blown mosfet on the GPU line which I replaced. It started up without a battery, then when I added the battery back it wouldn't start up again.

    As a result, there were some blown components around the BQ chip. (The BQ chip itself - BQ24780S, the low side battery mosfet (shorted), and a resistor -> all replaced)

    Now, with a new battery the system will start up and run off...

    Tv Philips 55PUS6031 no image, backlight ok
    by Raulnn
    good night! I have this TV, with quite poor build quality. It has a tcon integrated into the panel, a single flex from the tcon to the panel, and the 2 panel controller boards joined by glued flexes. There is no way to separate them.

    The symptom is that the image is not visible, but the backlight works. How to know if the problem is in the main or in the tcon-panel? I can't override zones.
