    LG Monitor L19NT-A with interference on screen help

    Hi guys; I already posted in the computer forum but did not get any tips on this Monitor issue, may this is the right place to post this issue!
    I send new Pic how this intermittent fault goes away by pressing 2 fingers against each other in the middle top edge of the panel.
    Any help would be appreciated

        Nice vid. Your Mr.Buzzer is a interference suppression film capacitor 450nf, 275V. I'd check that first with a capacitance meter. It should read 450nF. With an Ohm meter it should be 1Meg and charging up a cap. You can find these caps on other power supply boards from other LCD monitors and TV's. Swap it, check your display again for noise in the signal.

            could try putting something there where you put the pressure, for better contact, then reassemble, seems like loose contact in that section.

                Acer Nitro 5 AN515-54. displays on the external monitor and works fine, the issue is NO display on the internal screen
                by DqMagetz
                Good day!
                I have a customer's laptop — Acer Nitro 5 AN515-54 (EH5VF - LA-H501P). It has a display on the external monitor and it's working fine, but the issue is NO display on the internal screen. I already replaced the eDP cable and checked the LCD connector pins.

                Here are the voltage readings:
                • Input – 19V (stable)
                • +LCDVDD – 3.3V briefly, then drops to 0V
                • EDP_HPD – 3.3V briefly, then drops to 0V
                • PCH_BKL_PWM – 2.2–5V briefly, then drops to 0V
                • EC BKOFF# – 1.8V briefly, then drops to 0V
                • PANEL_OD_EN – 0.3V

                Is it possible that the EC chip is corrupted or damag...

                AOC U34G3XM, new monitor, black screen with backlight on, possible shortcircuit during dissassembly
                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...

                Dynabook Satellite Pro C50D-B-100 - BIOS Issue, Black Screen
                by wizard13
                Hello everyone,

                I am experiencing a BIOS-related issue with my Dynabook Satellite Pro C50D-B-100. When I power on the laptop, the screen stays black, and there is no response from the system. I suspect a corrupted BIOS.

                I have checked the forum and the available documentation but could not find a solution specific to my issue.

                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...

                HELP - Contrast/brightness issue with subtitles on screen
                by cloudy
                Hi everybody
                Since day one I'm having an unpleasant contrast/brightness issue on my Asus laptop.
                Basically while watching movies, if subtitles appear on screen, the contrast or the brightness of the entire screen increases a lot (not sure if it'is brightness or contrast), disturbing the viewing of the movie.

                Last year I replaced my screen because got damaged and this contrast/brigthness issue persists. It happens only on the laptop screen, in fact If i plug an external HDMI screen the issue does not occour on it.

                It occours both on ubuntu and windows...
