    It looks like the monitor was exposed to rain...

          Better look for a donor with a broken screen and rearrange your matrix.

            I don't have a doner. I noticed that the leds don't work are all nearby. And there Is 2 components at the estremità (meaby 2 diods). Can be them the problem?

                Possibly one of them is bad, and the whole segment will then stop working.

                  But i don't see a separation in the led strips 😭. I have a test Power supply, i can apply Power on each One by One to see the One that Is faulty?
                  At witch voltage the led works?
                  You meaby miss another question. The sheets inside the monitor have an orientation?
                  Thanks

                      Is there a metod to determinate the correct orientation of them?
                      For the leds testing? Can I test them One by One with a Power supply?
                      Thanks you so much

                        These sheets should have the correct sequence, the first one is thick (plexiglass) and should be positioned correctly up and down, do they have any protrusions or slits on them? Then thin ones (1 or 2 sheets), if there are two thin ones, then you also need to lay them out correctly (which is the first, which is the second... Here it was necessary to remember the sequence.

                          The sequence is correct. Meaby i reverse upside down One or 2. Can be a problem?
                          Can I test the led singularry?
                          What Is the tension of the led?
                          Thanks

                            I test each led individually and each works fine. Now I don't understand.. can the problem be the two components at the extremity of the section that doesn't not work?
                            What Is that?
                            Thanks

                                I have an HP model : 14-cf0011nf and I want to change its display screen (it has an original 14" full HD TN 30 pins panel) which works without problem but I want to put another screen with an IPS panel, the problem is that I tried several screens but there is no display except with the original screen, I never had this problem before I changed hundreds without problems but this PC is not 'accepted than its original screen
                                otherwise on the motherboard it displays edp and I don't know, do the panels I tried only work with the LVDS protocol?

                                Hello Badcaps Community,

                                I purchased a preowned AOC monitor that is not working and out of warranty. It was sold as not working. I am looking for guidance on self-repair. In particular, I am after the firmware for the monitor. At the end, I have included monitor model information and links to pics and vids of the issue.

                                The problem is that it will not display a picture on any of its inputs. And the on-screen menu does not appear. The power button works properly. It powers on with the remote as well. But the on-screen menu does not appear, even when not connected to any...

                                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...

                                Hello again everyone,

                                This is my latest mission, to try getting this Sony tv back to normal working order…

                                I've only just got it today, when you power it up everything is as should be, in fact it works perfectly for a few minutes then the screen starts getting horizontal lines on & eventually the full screen goes back, I will upload photos of the problem & also some photos of the board etc. You might notice that I'm busy trying the tape method, I'm not sure exactly where the clock lines are so I'm just guessing & hoping for the best lol . I've already tried...

                                Macbook Air M2 A2681 Kernel panics after screen replacement
                                by reformatt
                                Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".

                                It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...
