      Yes - steady hand, steady eye, tweezers and a lot of luck.

      There are videos on soldering smd components on youtube
      http://www.youtube.com/watch?v=EWeAOemTY_E
      However before going to a lot of effort you can "piggy back" it that means put a new fuse on top of the old one. You could even use a non smd fuse to try

      You need to get the correct rating

          CuriousInventor makes excellent soldering videos. Excellent focus, clarity, and great explanations on WHY the techniques work or not work.

              Like I suggested you could just piggyback it.

              If you are sure it is open, its not going to matter if it breaks.

              Obviously you are going to need a few extra tools - like this - hah hah

              Or you could do this http://www.youtube.com/watch?v=TyUm6hJ2vK0

                  I am sure that Budm's workshop could match that. Might not be as organized though.

                  The second video would be the way that I would do it. If you have a practice board have a go at taking them off and putting them back on that will give you the confidence to do it.

                    I have a friend that can do the job. Let´s see if I can find the replacement.

                    BTW: Has someone take a look to the Caps measures I uploaded?

                      Ok, guys I have more news about this problem. We have replaced F1 (fuse) and it blow up again, but this time worst, cuz now the display does not even start.

                      Any thought?

                      Do you know if Dell sells the entire board?

                      Thanks in advance!

                            Seeking Advice: Repairing Dell U3425WE Monitor with Faulty USB-C/Thunderbolt Ports
                            by Borse2008
                            Hi everyone,

                            Looking for some advice or opinions on what to do with a monitor issue I’ve run into. Apologies in advance is this crossovers a few forum categories.

                            I have a Dell U3425WE, which I've recently replaced with another model. That said, the original unit is still fully functional in terms of the display — it works perfectly over HDMI and DisplayPort. However, the USB-C and Thunderbolt 4 ports have stopped functioning correctly. The Issue:
                            • The 90W Thunderbolt 4 port (circled in the photo) no longer charges or powers any device, including laptops or MacBooks.
                            • There’s

                            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.

                            Guide me through repairing a Dell p2210f LCD ccfl backlight monitor
                            by DanPoka
                            I bought this p2210f dell monitor to fix. Schematic is the same as p2210.
                            Behaviour is that monitors comes on but then backlight switches off almost instantly. If I look with flashlight I can still find the "No signal message". So definitely a backlight issue. Trying to advance the issue I proved that the protection circuit is switching off the backlight by shorting out C3 and resistor to disable the INL chip then re enable by removing the short.
                            This is where it gets interesting. When I disassembled the monitor to solder leads on c3 capacitor I noticed the backlight flickered...

                            Hello. I have a problem with my AOC 27 monitor, specifically model Q27G2WG4, which I have been using for 3 years. The monitor stopped turning on: when I turn it on, the backlight turns on, the indicator starts glowing white, but the logo on the screen does not appear, and there is no image. However, if I check in the Windows system, the monitor is displayed as connected and working. I tried connecting it via HDMI and DP, but the result remains the same. If I turn the monitor on and off multiple times, it will eventually start and work. However, when the monitor is working, there are no issues....
