    Ugreen HDMI splitter missing a pulldown resistor

    Odd one I've found. This splitter likes to cut out - on my Xbox Series S the display/audio would randomly go to black for a few seconds - on my PC the monitor would flicker several times before eventually staying on. A few others have reported similar issues. Couldn't be bothered returning it for the sake of £8.

    I pulled it apart and found it is driven by a Texas TS3DV642 mux/demux. There appears to be a missing pulldown resistor on the HPD line, it is just left floating. Adding a 100K pulldown to ground fixes the flickering.

    (Not that this is worth the hassle for an £8 splitter)

      Xiaomi mi 9T missing resistor
      by badcap111
      Hi, while trying to replace a broken screen connector on the motherboard, I knocked off a resistor next to the connector, and the resistor vanished. I have tried to find out the value of the resistor by looking at the schematics, but I cannot find the value. The ID of the resistor, or what you should call it, is R6400.

      I don't know if the resistor is necessary for the phone to function, and the connector is still not soldered on to motherboard. I have contacted Xiaomi and asked them if they know the value, but they want a proof of purchase, which I don't have.

      Is...

      Missing resistor on BQ ILIM pin. DA0P5JMB6D0
      by liquidzorch
      Hello. I can't find the schematics anywhere for this motherboard, does anyone have one, and can give me the resistor value for the BQ728H missing in pic below? I already read the dadsheet, and this resistor value is calculated, so I can't just go with whats in the "typical" diagram.

      On a second note, could this resistor cause it to only boot with the battery and not the charger? It boots fine with a charged battery, but will not turn on with the charger (nor charge). The 19v does not get past the first mosfet, it recieves pulses to turn on, but something is preventing it....

      Dell 2209WA - power supply - Fusible Resistor replacement
      by jinu_j
      Hi

      I am trying to repair an ancient Dell 2209WA Monitor which suddenly shut off with a pop sound. On investigation found that one of the fusible resistors had blown. Further investigation identified multiple components as faulty because of which the fusible resistor blew. Please refer the attached circuit diagram showing the components that were found to be damaged.

      1. FR950 - blown fusible resistor - 0.2 Ohm 1W
      2. Q950 - shorted Q950 MOSFET - 650V 10A N Channel Mosfet
      3. R835 - Blown Resistor - 20KOhm SMD resistor
      4. D930 - Shorted Schottkey Diode...
