    Issue with HP W2338H Monitor

    Getting the 2 seconds to black error. Screen is still on and visible with a flashlight. I have dissembled the monitor and checked for bad caps etc. I have another monitor of the exact same make and I did some experiments first swapping the video board and power board separately to see if I could narrow down the issue. I have come to the conclusion that no bad caps or boards are present. Same issue with the known working components vs the orginal. If I switch the entire screen assembly, the monitor works fine so I am assuming that it is a ccfl issue. Any recommendations where to get the correct parts? Would prefer a modular replacement, as I didn't see how to actually remove the ccfls. Model number on the unit is Samsung LTM230HT01 G03 7w9e12a920

      It works with the power board and the video board on your other monitor? If so, it must be the screen. It couldbe that one of the tubes is faulty and causes the power supply to turn off the inverters.

      Does the screen appear to work fine in those 2 seconds that it works?

          Exactly. Screen functions fine. Back lights are just shutting off.

                  Do you hear any buzzing sounds coming from the LCD panel while it is on for the 2 seconds? If so, then defiantly some arching going on with the tubes.

                      For a week or so heading up to the failure there was a buzzing noise when the monitor was on. That has gone away since the failure.

                          Def a ccfl. Just took them out and found 1 bulb broke. Downside I broke the LCD putting it back together. Any ideas where to get a replacement LCD?

                              If you go to eBay and enter LTM230HT01, you'll get several hits.

                                  Did that already. The revision number is different. Mine is g03. Those are a09 and say touch screen which this monitor isn't. Will those still work?

                                      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...

                                      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....
