    Remove capacitor without damaging the board

    I have an old Mikrotik board with one bulging capacitor. It still works, but the cap doesn't look healthy.

    I have tried replacing it, however it seems to ignore my soldering iron like it's a toothpick. I do suspect an industrial-strength lead used during manufacturing.

    How do I remove it without damaging the PCB and (more importantly) surrounding components which might be more temperature-sensitive.

        Im going to take a guess that its a through hole cap;

        I add a small amount of flux at the base of each leg of the cap from the back of the board (not so much the leg); hold the tip of your iron on one leg of the capacitor at a time until the solder melts enough to push that leg through, swapping legs working the cap until its free;

        A good iron makes the world of difference;

        Other people on this forum will likely have better methods, but this works for me 👍

            Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
            by Tynan Dill
            I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

            Upon bringing it home and plugging it up, it showed a standby light.

            I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

            The screen seems to blackout and stay black, but with a flashlight I can see the display.

            With my Playstation 4 connected via HDMI, and running a game I can hear sound.

            Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
            Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

            Problem

            This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

            TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
            by howardc64
            All left and right refers to looking from rear of TV (or looking from front with TV upside down)
            • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
            • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

            How do I remove the chip from the board
            by gusto
            I am new to hot air soldering. I need to remove one chip from the board. I have a hot air solder and I set the temperature to 350°C. I slowly started heating the chip, but the solder didn't melt. I heated it for about 5 minutes, but the solder still wouldn't melt. I increased the temperature to 450˚C and still nothing. After a while, the board started to change color, but the solder still didn't melt.
            Fortunately, I'm testing it on old network switches to see how it works.
            What am I doing wrong?
            I've seen a lot of videos on youtube and everyone got the solder melted and the...
