    Hello, I have a problem with the monitor, it worked normally for some time and now, after moving it to another place, it turns on for a fraction of a second and goes out
    it is not the fault of the power cable or vga because I have already connected several and always the same. If the monitor turns off and on with the button, the same will turn on for a fraction of a second and again black, When I enter the options on the monitor, you can barely see them
    I have read various posts and it turns out that it is either the fault of the inverter or the power board? in general, I do not know if it pays to repair

    Have you checked this monitor on 3 computers? Were you looking for cold solders on the monitor board?

    Check that the capacitors on the monitor electronics are not swollen. Unscrew the monitor and check.

    Cold February of backlight fluorescent lamps, modification of protection or re-soldering.

    yes, 3 sets of different cables
    February I look below, I gave photos ... maybe you will see something and tell you because for me 1/10 is cold xd but maybe because I have little experience in searching

    They look functional, the photos below are also condensed and February too

    The C58 on the green plate ("lonely" bottom left) appears to be swollen.

    that is, try to replace it for now, if it did not help to look for other reasons?

    I already had such a case, replacing one capacitor is a job for a short time, other capacitors also dry up, so I propose to replace all electrolytes and the problem is solved. The repair cost is a penny thing.

    Yes. You can start there. Such a capacitor is worth one zloty. It's worth checking out. Remember to buy a LOW ESR capacitor with the same capacity and the same or higher voltage. Also remember about the dimensions, especially the height, so that it fits in the place of its predecessor.

    Not only the C58. There it seems to me that there are a lot of solders to improve, but due to the quality of the photo I'm not sure. For me, when the screen went out, such an improvement in solders brought a result

    OK, I will remember, well, half of the solder looks strange, but with better light I will try to apply it soon, I will let you know what and how

    Let my colleague correct all February that look cracked against the light. I see at least a few such places in the photos.

    And after improving the solders and replacing the conduits, if it does not help - replace the fluorescent lamps.

    Of course, as long as it is profitable, I have several monitors with released fluorescent lamps and somehow I do not have the energy to replace them due to low profitability, but ... after replacing the capacitors in several other monitors - the image returned and the symptom was identical to yours - it turned on for a second and went out.

    Good luck

Topic summary

The discussion revolves around a Belinea 10 19 27 monitor that turns on briefly before going black. The user has already tested multiple power cables and VGA connections without resolving the issue. Responses suggest potential causes including faulty capacitors, cold solder joints, or issues with the inverter or power board. Users recommend inspecting the monitor's internal components, particularly looking for swollen capacitors and improving solder connections. Replacing all electrolytic capacitors is advised as a cost-effective solution. If these repairs do not resolve the issue, replacing the fluorescent backlight lamps may be necessary, although this may not be economically viable for all users.
