    problem with replacing lcd screen

    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?
    If anyone has any information on the subject I would appreciate it​

              I wonder if it's not the bios that blocks the display like with incompatible wifi cards and if there is a way to modify this, if anyone has already had this problem and managed to solve it

                  Hello,

                  Your screen is HD (N140BGA-EA4) and you try with 2 models FHD ! (NV140FHM-N69 , NV140WUM-N43 are Full HD 1920X1200)
                  Please try with an HD screen. (1366X768)

                      N140BGA-EA4 its a FHD 1080p TN and works perfectly but with any another FHD IPS not working, i tried with NT140WHM-N41 (1366*768) its worked, but my goal is to have a functional FHD IPS screen

                          Does anyone know about 16x2 LCD screens used in alarm keypads?
                          by Ady2017
                          I have got an old Gardtec GT595 alarm which has got a faulty keypad with a failed LCD screen. This was apparently a very common problem with these and many people have had to replace the whole alarm because of this problem. Somebody claims to be able to repair the keypads by replacing the screen and I have tried it myself by replacing the LCD with a commonly available HD44780 1602 16x2 Serial LCD screen but it is not working. I am sure it is a problem with a driver or simular which is not allowing the screen to talk to the rest of the electronics. Does anyone know what this original screen was...

                          ipad pro 9.7" blew a SMD component while replacing the screen πŸ€¦β€β™‚οΈ
                          by ipatch
                          i have an ipad pro 9.7" (1st gen) A1674 where i replaced the screen, but never attached the screen to the frame/chassis (glued down) due to the ipad being previously dropped so the new screen would never fit in the frame properly. so i need flex/bend the chassis to eventually fix the new screen in properly. so i temporarily just applied blue tape around the edges of the screen to keep it in place. when watching videos with the ipad the screen started flicker, so i though maybe the new quasi cheap amz screen i purchased was going out. so i disconnected then reconnected with power still on,...

                          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...

                          Dell G3 15 3500 - Battery bug (black screen and flashing keyboard backlight)
                          by HTR-Informatique
                          Hello,

                          YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo

                          I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.

                          On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.

                          I also changed the screen because the PC fell and the screen was broken.

                          I changed the battery with a new and original battery.

                          I also had corrosion/oxidation on the...

                          Maldischarge-link that fixes it with replacing caps
                          by r-p
                          Starting this thread because Capkid doesn't seem to be reprogramming controlboards anymore (LG 60PZ950 with red maldischarge) and my game-plasma also has maldischarge (Hitachi 42PD3200). So I will grasp at straws to keep them running. I am extremely bad at throwing stuff away.

                          Is there any merit to this link?

                          Very short version: Specific caps seem to loose their capacitance and/or increase their ESR. This may cause the maldischarge. Replace them with better/bigger/newer ones and problem solved.

                          From the limited knowledge I have on the subject, I think...
