    problem with hotair station LK852D-2

    Hi, i have a hotair station LK852D-2 , and the problem is about the air flow is little and hardly to getout any air flow from it, i unfurtanitly replaced the potinmeter 500k ohm with new one, but it never solved the problem, and then i unsoldered from the board as you can see in the attached photo, and that make Some parts of the circuit diagram been damaged, and I need someone who has the same circuit diagram to provide me same photo of the diagram, especially the place where the 500 kΩ potentiometer switch is located( the place of 500k ohm potentiometer is indicated it with red arrow in the attached photo). is there any solution to the low air flow problem? What is the reason for that? Thanks in advance.

      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

      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...
