    HP ZR2440w single edge LED misbehaving

    I've recently started having a part of the bottom of my monitor start to give me backlight issues. Sometimes it works great with no dimmed sections, other times there is a segment (as pictured) that is dim, other times the segment is about twice as long as pictured. It seems to be random, though if I power-cycle the monitor, it will get worse/better randomly. Is this potentially a capacitor issue, or would a capacitor cause different symptoms? Would a faulty LED sometimes fail to power on intermittently?

    Got the monitor disassembled (The front bezel is tool-less and a PITA!), doesn't appear to be any extruding capacitors...

      With an issue like that I'd suspect the LED strip.
      Something like a dying LED or bad connection.

          To follow up on this, I was able to narrow down the bad part to the LED strip that runs along the bottom of the Display by swapping the PS + Mainboard between identical monitors. Unfortunately, it doesn't appear the LED strip is available anywhere, so I guess I am out of luck and have to get a new monitor.

              Since you went this far, you can remove the LED strip and replace the bad LED with a similar one from a cracked screen. There are not that many models of LEDs for backlighting so it won't be hard to find a suitable one and it is a simple soldering job.

              A working TV? How boring!

                Shame to see that even Led monitors are failing in the same way as Tv's crappy, cheap Leds going pop.
