    Benq power board failed, no backlight

    I have a HP LCD monitor with benq power board. Last week, when i turned it on, the backlight turned off right away. I can see the image moving on the screen using flashlight.

    I found out the whole thing was made by benq and there 're some discoloration( lititle darker) near the transfomer .

    I borrowed a ESR meter from my friend and all the caps are still within range. I suspect it is the transisitor that near the transformer.

    The transistor is FU9024N , a p-channel transistor, and i only have a multimeter

    Anyone know how to to test it using the multimeter?

      Well you can find a few transistor test methods out there. i always skip them because my multimeter has a nice little feature where you slot the transistor in a socket and switch it to "Transistor test" mode. look around and you should fine one.

          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....

          Samsung LN46C630K1F – Intermittent Backlight, BN44-00341B Power Board

          Summary for TL-DR readers:
          • Backlight is intermittent, may come on with TV boot or not. No flickering, never fails during TV on.
          • Have obtained Samsung schematic & service documents - Can upload if helpful.
          • Have read ALL applicable threads
          • C1818 and CP820 replaced as low hanging fruit
          • CN802 data taken for normal and failed BL operation. SUMMARY: Pin 2 - 5vDet = 3.52 @normal, 0.0 @BL fail. Pin 6 - EPWM = 1.631 @normal, 1.058 @BL fail.

          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
