    Dell 1905fp missing resistor

    I'm working on a Dell 1905fp ultrasharp monitor's power supply.

    I was in the process of repairing it when a surface mount resistor from the solder side disappeared.... into the carpet/abyss.

    It's R134.

    I would appreciate some help in determining its value.

    Thanks ahead of time,

    Hello r134 is 47K. I have this board on my work bench.

        I don't suppose you could tell me what resistor R125 is, could you? I'm having a terrible time finding it online and it is the last piece of the puzzle for this board.

        Thanks!

          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...

          Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
          by Bowline
          My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

          Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?

          My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
          The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
          I have tried multiple different Dell power adapters. My Dell...

          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....
