    Problem with resistor HP 450 G1

    Hi, I have the following problem with HP 450 G1
    When I turn on the charger, the element I showed (resistor 330) becomes very hot and hits light current when touched. The laptop does not turn on.
    I'm a beginner so I'm asking here if you can give an idea where to look for the problem
    Greetings

      Re: Problem with resistor HP 450 G1

      follow the trace, but i bet one of that diaodes is shorted

      remove resistor and i bet that one side have voltage and other side is shorted

          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...

          Problem with LG Plasma 60PM6700 - Random power downs
          by theone111
          I have an LG Plasma TV 60PM6700 for the past ~12 years.

          In the last ~3-4 months I have been having some issues.
          1. Problem: It started with random picture disappearing (sound still worked).
            Frequency: Happened about once a week.
            Solution: Had to turn off TV wait a few seconds before turning it on again.
          2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
            Frequency: Happened about once a week.
            Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
          3. Problem: TV shuts down

          Need help to replace burned resistor in 350w atx psu
          by mikey5791
          Hi to all forum members,

          Got this faulty 350 watt atx psu dirt cheap from a local online seller as i am keen to use it as a learning tool to repair faulty power supply.
          The faulty part is quite obvious from the burn area near the 16pin KA7500 BD pwm. The fuse is still intact with good continuity.

          Upon power on ac, there is 5vdc standby power on cathode of diode D14 and about 10vdc on cathode of diode D13.(This should be the aux power to generate the 12v and 5v rail.)
          Initially i replace the two burned resistors near my marked red arrow to 200 ohm resistor...

          What resistor ohm will work better to repair this waterpik?
          by artvandalai
          The resistor on this waterpik blew. I changed it with the a similar spec 47ohm 2 watt yageo resistor but it still keeps blowing the resistor. Checking with the multimeter the motor, capacitor, diodes, and thermal fuse all checked normal. Will a higher ohm resistor work better? What ohm resistor will work better to repair this waterpik? This video is showing the repair with a 56 ohm resistor https://www.youtube.com/watch?v=_J7_rV7ui1Y

          Thinkpad X1 Carbon "LMQ-1MB 12298-2 48.4LY26.021" VCC3M problem
          by Zeonalbasta
          i have a problem with thinkpad X1 carbon gen 2 "LMQ-1MB 12298-2 48.4LY26.021"
          The laptop was turned off because the MOSFET was not transmitting voltage. After checking it turned out that the gate pin on the MOSFET was the problem, because it was producing an inappropriate voltage. and it was discovered that the problem was with the Think engine, so I decided to reprint each pin, and finally the mosfet could work properly. However, there is another problem, even though the voltage has been supplied to the laptop, it still won't turn on, there isn't even an LED indicator. After double...
