    Re: Issue with Westinghouse 19" LCD Monitor (large pics)

    Crabs?

    Anyway, I didn't know if the Taicon caps were better Quality or not since none of them are bulged. I took some more pics of the back of the board. let me know what part of the board and I can take very close shots if I can't find it myself.

    Thanks,

    Bob

      I can see 2 fuses
      F200 on first pic, at bottom in middle
      F102 on fourth pic, top left with a M or W on it
      suspect there may be a third possibly F101 (not sure about that)

        He refers to the 8 legged ICs near the transformer.
        If you can, replace those Taicon for Panasonics as a preventive measure.
        And check the fuses Bob describe. On the model discussed here before, with the different PSU from yours, F200 was the culprit. Check them both, F200 and the "W"/"M" one ...

              look at the chips they have crabs on them. Or am I mistaken>>>???



              I have a untested board for your monitor. Maybe you want it or parts off of it?.

                That's Realtek logo. Not that one. This is microcontroller (aka minimalist cpu with few control outputs and few inputs).

                The IC they were referring is FET drivers in 8 pin DIP package (on the inverter/power supply board). Black square, dot or notch for pin 1, with 4 legs on each side in parallel.

                Cheers, Wizard

                      I have an acer AL1916Wa LCD monitor, and it does not turned on. The power sorce and the controller card are the same
                      I have a monitor that has exactly the same source and the same control card, as yours, but mine does not turned on, I check the voltage of the source 13.8v and 5v are ok. what can I do.

                        I tested the two fuses. F102 is good. F200 is bad. It has a #3 on it as best I can tell. Where do I get one of those and how do I know the value of it?

                        A parts board would be great but I hope all I need are the caps, chips, and the fuse. I already ordered the mosfets off of Ebay.

                        Thanks,

                            I would suggest starting a new thread. even if you barrow bcuda's pictures. It gets very confusing for people to reply to multiple questions from multiple people in the same thread.

                                F200 as in our models ....
                                Get new caps, MOSFETS and I think the fuse is either 3 or 4 amps (that info is around this or the L20146NV thread that I started). Mine is bridged with solder.

                                  Just an update, The caps and fuse are in. Waiting on the chips to come USPS. I thought they would be here today but not luck. Maybe Monday.

                                        The fuse on the bottom of the power supply board is a 4amp surface mount fuse. Mouser.com carries them, they are part number
                                        652-SF-1206F400-2

                                        We have repair many of these units and every time its the caps, mosfets and the fuse.

                                          Agree : caps going south kill the mosfets, that in turn blow the fuse.
                                          And I recall seeing the part # and amp rating somewhere around here, just can't remember where. Thanks for the info, man!

                                            Hello,

                                            I am currently trying to help a ONG by volunteering to help repair laptops, it's something that i have been into since 2017, always watching videos, on discords, forums etc...

                                            I have an HP ProBook 4510s laptop that does not power on and has no indicator lights, which suggests an issue with the power supply or the motherboard.

                                            I started by verifying that there is voltage at the input of the motherboard, confirming that the power adapter is working correctly. However, when I checked the voltage at the output of the first MOSFET (Q1032), I found 19V at...

                                            Good day everyone.

                                            I have been scratching my head with a Lenovo laptop I got in today.

                                            The laptop had no power and taking no amps from the power supply. Checking voltage showed 20v only on one side of the first mosfet. Took it off and replaced it and then same story. Took off second mosfet and then the first mosfet had the right voltages as well as 25v on gate is it should. Replacing the second mosfet the problem started again.

                                            Even using a wire to bypass the second mosfet does the same interference with the first mosfet.

                                            Would anyone...

                                            How do you test MOSFET in laptops ?

                                            I tried to use this method:

                                            Testing an N-channel MOSFET:

                                            Step 1: Discharge the Gate (turn off the MOSFET)
                                            Place the black probe (COM) on the Source (S) and the red probe on the Drain (D). The multimeter should show no continuity (high resistance or "OL" – open line).
                                            Then, touch the black probe to the Source (S) and the red probe to the Gate (G). This discharges any stored charge in the Gate, turning the MOSFET off.

                                            Step 2: Charge the Gate (turn on the MOSFET)
                                            Now, place the red probe on the Gate (G) and the black probe on the
                                            ...

                                            Here's another LCD monitor repair: Westinghouse L2210NW.
                                            Quick specs: 22” CCFL backlit LCD, 1680x1050 max resolution (16:10 aspect ratio)

                                            I got it with a bunch of desktops PCs from a repair shop that was trying to free up space a few years ago. It seemed like a cheap monitor, so I didn't really care that much at first when I picked it up (and indeed it is, picture-wise.) But hey, free is free, so I can't complain. Moreover, it looked clean and the screen didn't have any significant scratches or blemishes.

                                            Pictures of the monitor outside/case after a brief...

                                            VGA MOSfet permanently shorted and loss of MOSfet pad
                                            by Nooy
                                            Hello everyone, I recently found this badcaps site and super Learn Electronics Repair youtube channel. And I wanted to learn how to troubleshoot power supplies and VGA cards and how to practice soldering, since I already have a properly defective piece of them. I am currently trying to solve two problems:

                                            I have a Gigabyte GV-RX460WF2OC-4GD type card. I managed to find the faulty MOSfet (AON6414A) on it, which I replaced. The card starts up, but after about half a minute, the MOSfet in the same position will be shorted again. Is it possible that the PWM controller driving the MOSfet...
