    Identifiyng a component on board MSI - MS-17FK : Bravo 17 A4DDK

    Hello everyone,

    I'm begging for help on this one. A customer came with a laptop that has a broken screen. I also checked the board and found a blown component on the board. I assume it has something to do with the backlight because even the broken screen has no backlight. Otherwise, the laptop works fine on the external screen.

    Can someone help me with identifying the blown component? I wasn't able to find a schematic for this motherboard or find the right IC from the marking on it.

    Thanks, everyone! Have a great day.

      Hi, I think it's an APL3512ABI-TRG.

          Nice find! Looks to be a logical device and the markings do match - these are common to being used for USB connectors so there should be plenty of equivalent devices on the market.

          Review DIODES Inc. or similar. 'USB Load switch' with a 2A rating, etc. but must be ACTIVE HIGH for the enable pin. SOT23-5 package.

                  In such cases I take 1st similar donor board and change without reading markings when you see it's definitely backlight driver, never had any issues so far.

                      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.

                      Assuming...

                      LG 47LB5DF blown power supply board
                      by cmlewis89
                      Hi folks,

                      I'm new to this forum. So my trusty 17-year-old LG 47" LCD recently died. As I was booting it up, I heard a hum followed by a loud bang, sounds of pieces flying around, and loss of power to the unit. Inspecting the PSU, I saw two obvious problems: a blown thermistor (bang + flung pieces) and a visibly bulging main cap. Inspecting as many components as I could with my Fluke MM, I diagnosed that the following components on the "hot side" of the board were also bad: one of the 2 main MOSFETs, main 8A fuse, small cap (25V 47uF) connected to main caps, and a blown...

                      • 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

                      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....
