    Hp z23n monitor shows horizontal lines

    HI ALL
    i have the above board 715G7282-P01-001-0H3S WHICH SHOWS horizontal lines.

    on power board i noticed 3 capacitors that changed color.
    these 3 capacitors are connected to the positive side of main capacitor.
    i have no schematic and i do not know the values.
    those are c921,922,923.
    c921 is removed.
    how can i substitute.


    thanks

      HannStar Hanns-G HC194d LCD monitor repair
      by momaka
      Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

      ASUS VA27EHE randomly unstable
      by Sharx112
      Hello community. I've got an ASUS VA27EHE with a Panda LC270lf1l01 panel that started to behave strangely. A bit of intro:
      If you power on the monitor without any inputs it turns on, displays the ASUS logo, shows no signal and goes into standby normally. When you plug it via HDMI sometimes and more recently, most of the times, it distorts the bios logo with horizontal lines, then when loading into windows 50-50 the windows emblem also is in horizontal lines. And after the system loads it almost always works properly, lol. On some rare occasions a part in the top of the monitor is being distorted...

      Samsung QN70Q6DTA Ghost or horizontal lines after tape fix horizontal line
      by Ihandyrepair
      Hi guys

      I just started fixing 4k TV few months ago. so I am still learning a lot
      I got this tv from friend complaint is ghosting or horizontal lines on image.

      never saw the original symptom but I took the tv back home. the funny part is that after bringing to home, the tv worked fine no issue for 3 weeks.
      then it started to show the ghosting white image.
      I started using the tape method, but this tv does not have a T con board and it has only 1 ribbon cable from main board to the tv panel.
      it has 3 thin small boards at the bottom of the...

      Dell monitor PSU vs Dell laptop PSU
      by keepread
      Hi there!
      Someone gave me their old monitor, it's Dell S2715ht.
      The owner was using it when his PSU began to smell and then to smoke. It literally began to melt. He turned the monitor off, pulled the PSU, and ditched it because it was smelly even after it cooled. So I got the monitor but not the plug.
      Now, I tried to bring the monitor back to life, by plugging one of my many Dell laptop PSUs. They are of the same 19.5V, and the wattage of the laptop PSU is higher than that which the monitor is rated for. Visually, the socket on the monitor seems compatible, and the plug plugs...

      ACER BM320 Monitor - Horizonal Flickering Lines After a While
      by reessi
      Hello,

      The monitor started off showing flickering thin (1 pixel) lines horizontally every say 3mm..

      They are black on the right and gradually fade to nothing on the far left.
      They start either after 5 mins or up to 2 hours after so annoying for testing.
      They flicker continuously very fast! With a slight pause milli-second every second.

      Initially I cleaned the LVDS cable and connected to the T-Con and then it worked fine for 3 weeks but not sure if this was just co-incidence.

      I tested each half by removing the first the left flex from...
