    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...

              Looking for help with a Viewsonic VP230mb where the backlight comes on only momentarily
              by lostone
              Hello, I came here after finding some similar questions asked on other monitors and hope someone here can help me get an ancient Viewsonic VP230mp (23" 4:3 LCD) back to working condition.

              First a little background, I have a background in computer and electrical engineering, and I'm smart enough to know I know nothing about LCD displays and how they work. For this topic I'm as green as they come.
              When the display is turned on the viewsonic logo displays in the uppper left for 2 seconds then the screen goes black, the power LED is green (on) and when a computer is connected...

              LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
              by Hakuu
              Hi There,

              This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

              After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

              More Details

              Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt...

              Panasonic TC-P54VT25 No image. A or D board?
              by canadaboy25
              I have a Panasonic TC-P54VT25 that will power on and prime the display but there is no image at all.

              The panel is primed as there is a slight glow from the entire panel. This means the problem should be logic related. The service manual also confirms this and recommends replacing the A or the D board.

              I have tried to get the TV to display the test sequence but I have been unable to and I don't even know if this TV has a test sequence or not. I tried following tom66's instructions in post #3 on this thread https://www.badcaps.net/forum/showthread.php?t=26790. There was...
