    HP L1906 LCD Monitor

    Have an HP L1906 LCD that failed to power on after lightning storm. Opened up and found a number of bulging caps on power board. All were CapXcon. I ordered various size Panasonics and U-Chemcon to replace. Repair went beautifully and all is working well now. Guess lightning storm was just enough to put the caps over the edge. Sorry I didn't take pics, but caps looked pretty much like any bulging CapXcon gone bad. Hope this helps someone.

    If it can be assembled, it can be disassembled.

    Hello, i have the same problem, black screen and no light on the power led.
    I have removed all the screws but i don't know how to disassemble the monitor.
    Can you explain to me how to remove the bezel to access to the electronics, please ?

    (excuse my for the faults of language, not english)

    Thanks for your help

      It's been a while since I did this, but I can tell you what I remember.

      1) Bezel/trim ring just pops off the best I remember. You have to pry it starting in corners and working your way around ... and be gentle.
      2) The rest of the parts come apart using a small Philips screwdriver and a small star/torx driver if I remember right. You may have to remove a label/sticker to access a screw or two.
      3) Remove the base/stand using the clipping devices. Then remove the tilting mechanism by pulling the plastic cover off, then unscrewing the 3-4 screws anchored to the monitor chassis. This is important! Monitor will not come apart unless you do this step.
      4) NOTE: If the monitor back doesn't just come right, there is still a screw attached somewhere ... find it!
      5) Remove the backlight wires and and the front panel connections and draw their orientation/connection in your notebook or take a pic.
      6)Remove the two boards. Again disconnect the wiring harnesses and document their connections.
      7) Document or take pics of everything as you go through process. Everything should come apart fairly easily if all screws have been removed.

      That's about all I can remember. Last piece of advice is to test it out after the repair, BUT BEFORE you put it completely back together.
      If it can be assembled, it can be disassembled.

        Hello, and thanks for your response.

        I have removed all the parts of the monitor to get back the electronic board.
        If i look close some of the condensators, three of them seems to be in poor condition


        They are at the center of the picture at the edge of the board.

        Are they the same than in your case ?

        Thanks for your answer.

        Bye.
