    What component is this that burnt?

    Smelled some electrical fire smell from monitor. A few days later monitor would start to flicker and lose power and turn off. Turn on monitor and saw some part shooting electrical arcs. Evens though the monitor still works, I opened it up. The part looks pretty fried. Can anyone help me identify the part that is burnt?
    And what do I replace it with.

        Yes how odd - thought this was going to be the same board - anyway see if your board has the same cap in the same position at the other side.

            Anyone know the specs for those ceramic capacitors? I've never replaced those kinds. Just the typical electrolyte ones.

              They are all different , but usually have some numbers on, have a good look at the one in the position marked toast - may need a magnifier but not usually.

                Probably like 10nF - 47nF, high voltage (>= 1kV) ceramic epoxy coated capacitors.

                  Read the marks on C414 or the other blue caps of the same size. The marks on the burnt caps were most likely the same. As ben7 said, probably a few nF rated for 3 kV or higher (so far 3 kV for those caps is what i have seen regularly in monitors).

                    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...

                    Hi Everyone

                    Lately I am experiencing the deja-vu incident on one of the led monitor like this.
                    https://www.badcaps.net/forum/troubl...lashing-on-off

                    The monitor is HP 27es LED Monitor
                    https://h30434.www3.hp.com/t5/Deskto...e/td-p/6804692

                    The monitor will randomly blackout and display no signal and will recover again.
                    Sometimes need to power and off again to restore the display but...

                    LG 23MP55HQ LED Monitor turns off after a few seconds or flickers.
                    by Rick_1234
                    Good evening, gentlemen.

                    I have a problem with my monitor. It turns off after a few seconds or flickers. Shining a flashlight on the screen doesn't show any image, so I guess it's not the "2 seconds to dark" I read in the forum.

                    To turn it back on, I have to press the power button twice. Then after a few seconds it turns off again or flickers. See video.

                    Wise Wing F199 19'' LCD monitor - recapped
                    by momaka
                    Looking through my repair pictures and notes, it's been a long time since I posted anything in the LCD monitors section. So here goes that.

                    I'm dedicating this thread to one of the very first LCD monitors I repaired (if not the first one), which was more than 10 years ago now. The monitor is a Wise Wing, model F199. It's a 19” CFL-backlit LCD. I got it for free off of Craigslist in 2009 from a guy, who said he bought it for cheap from Wallmart and the monitor worked only for a little less than 2 years before quitting.

                    When I saw the Craigslist post, I wasn't...

                    4 weeks ago i launched Metro Exodus Enhanced and during cinematic advertisement part ( 30 fps ), pc just shutdown.
                    Also monitor flickered with NO SIGNAL 10 seconds after shutdown. So only monitor and pc was affected.

                    Next i pressed only power button, rebooted again and its fine again. Happened once and i cant reproduce.
