    what is this component ?

    The board is an inverter for 4 bulbs on a 15" screen.
    The board is a TDK PCU-P154E inverter.

    The device is marked "45", and it is 2.8 x 2.4mm

    I believe this is a fuse, perhaps 4.5A ???

    It is connected directly to the Vcc into the board and it is open.
    The board draws 1.7 amps, and it seems to function normally when I
    bypass the device.

    Any thoughts on what it is ?

      it may be a circuit protector.
      if it is then it's NOT the current on it - you need a datasheet to decode the numbers.

          I just repaired one of these inverters, the current when operating was about 1.8 amps
          Looks like it could be made by KOA, series CCP2 B or E. [45] looks like 2.5 amp current rating, fusing cuurent is 4.5 amps.

              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...

              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...

              A2991 Logic Board issue, 20volts 0 amps help!
              by Stephen
              Customer plugged in samsung monitor into the board and used it as a power supply, killed UG800 and UG400. I replaced those two with an exact donor board we had In stock and working, board pulls 5volts and then gets like 2.89 amps on the left side. The singular port is the port that failed. Used a perfectly working chips from donor (board was locked) Now I only get 5volts 0 amps on that power and then 20volts 0 amps on the two left side ports, I checked for DFU and nope nothing, computer not turning on. No shorts present anymore. I am confused as I used the exact components from an identical...

              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
