    VX2255wm won't turn on

    Hello,

    I have a problems with my Viewsonic VX2255wm monitor.

    Few days ago the monitor started to have a problem, the monitor was working fine but each time my computer was stopped/started the led of the monitor was blue and the screen was black, and when I tried to push the power button of the screen it seems to be frozen, Blue led and black screen. So I decided to remove the power cable and to plug it again and it worked.
    And I did it everyday.

    But today the monitor (with blue led and blackscreen) when I unplug/plug the power the blue light goes on during 2seconds, off during 1seconds and then ON again (Blue led light, black screen, power button frozen)
    And even when I shut the computer down my led is still blue.


    I tried to push power button during 30seconds, another power cable, another PC.

    So I'm here first to see if someone has already seen this sort of problems before doing anything. (NOTE : The whole screen is off, not just backlight, I can see it with my flash light)

    Do you think this problem can be a capacitor problem ? Power supply ? (So why plug/unplug the screen did the trick last days ?)

    Note (if it can help to see where the problem come from) : There was a power outage in my street on week ago that has ruin my Printer.

    Thanks !
    I will post pictures later when I will be able to disassemble the screen

                  Leaving default caps can damage my screen ? or it is just to avoid having issues in the future with the others ?

                  I have ordered all capacitors but I changed only one because I'm not a very good welder i don't want to damage a working screen

                      You can wait for monitor to fail again, mean while you can practice soldering
                      YouTube is a great place to learn.

                          by turmix
                          Hello, I'm working on a new deskmod pc project and have a problem with my monitor, an AOC U34G3XM, well, I may have bricked it.

                          The monitor was dismanteled and the separate parts parts integrated in the desk. the screen panel alone is on the upper part, and main board/video board + power board on the back of the desk (not enough place on the cover to fit it)
                          At first everything was working smoothly, then I decided to change the connexion between the video board and the screen for a longer one. Still working fine

                          During another reassembly, I made a mistake, and...

                          Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
                          by Ryan.man
                          Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

                          My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

                          This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

                          Having this very weird issue.
                          The owner of this laptop complained about screen being intermittent when opening and closing, and has been using the laptop on a thunderbolt video connection since the screen failed.

                          I swapped with a working screen from an A2141 waiting for parts.

                          The Os exhibits this weird behavior where it boots to to 1/3 the status bar, then it makes the boop sound. It's at the log in but for whatever reason the desktop isn't loaded.

                          The laptop boots fine into recovery mode. I updated from Monterey to Sonoma and the laptop still has...

                          AOC 27 monitor Q27G2WG4 doesn't display logo or image on screen
                          by 3D Modelka
                          Hello. I have a problem with my AOC 27 monitor, specifically model Q27G2WG4, which I have been using for 3 years. The monitor stopped turning on: when I turn it on, the backlight turns on, the indicator starts glowing white, but the logo on the screen does not appear, and there is no image. However, if I check in the Windows system, the monitor is displayed as connected and working. I tried connecting it via HDMI and DP, but the result remains the same. If I turn the monitor on and off multiple times, it will eventually start and work. However, when the monitor is working, there are no issues....

                          Dell 34 inch U3419W Monitor with thin stripes on partial screen
                          by ChristianBr01
                          Hello everyone,
                          I have a Dell U3419W Monitor that has some thin stripes on a part of the screen since Tuesday.
                          This lines cover about a third of the screen and appear for 2 seconds before disappear for another 2 seconds.
                          This repeats the whole time. I have not opened the case yet cause I had no time, but will try to fix it on this weekend. For me, it looks like a problem on the TCon... Am I right?
                          Does someone have seen this before?...
