It fits into the Dell fine, but there was no bracket for the inverter board. It’s a Samsung LCD panel, 1280×800 WXGA 15.4″ screen. I replaced an LCD on a Dell Inspiron 1525. I had to send this screen back and replace it with Rev.C1 screen. The new revision had two mounting brackets on the top and bottom and the screen didn’t fit into the case. I was replacing the LCD screen on a Gateway laptop and purchased a new one with exactly the same model number, but… the revision was different. Most likely the mounting bracket is permanently soldered to the frame. You’ll find this warning on most LCD screens.Īnd the old metal frame removed and goe on the replacement lcd? Try to find a new LCD screen that matches your screen.Īlso white tape that says “Do Not Touch” covers the area of the frame on top were the mounting bracket would go. Inverter or the piece on top (mounting bracket )that the bezel is attached to.Īpparently you are looking at a wrong screen. The replacement it has no screw holes on the frame for the I’ve googled everywhere and this blog seems to be the most helpful and knowledgeable, so I’m really hoping to get some glimmer of hope that I won’t have to put up with a broken screen for the rest of my laptop’s lifetime because I can’t afford a replacement screen. But apart from the size + backlight, is there any way to find out for sure if a certain video cable is compatible with my laptop? So my question is: How do I find out which screens are compatible with my laptop? What are the main sources of incompatibility? I know that my screen was TFT Active Matrix with LED backlight, so I can’t order any with the CCFL backlight. Obviously, I can’t replace my laptop screen with the exact model it came equipped with. The official vendor’s website lists the screen, but as out-of-stock, and at either $600+ or $900+. I have a newly released laptop with a messed up screen, and I can’t find any websites selling the screen part # or model # at all. If the old one still works, but the new doesn’t, your new screen is defective or not compatible.Īlso, you might be interested in how to troubleshoot bad video. You can test the computer with the old, partially working screen, as we did earlier. Make sure the cable seated properly, all the way down into the connector. If your new screen doesn’t work, check the connection first. This cable supplies data signal and power for LED backlight. Newer LED-backlit LCDs have only one cable connected to it. If the original screen lights up, apparently the new screen has defective backlight lamp. You can see a very faint image but there is no backlight.ĭisconnect the new screen from the inverter board and plug in the old screen instead (I assume it has working CCFL), as it shown on the picture below. Send it back to the seller for a replacement. If the old screen still works but the new one doesn’t, your new screen is defective. If your original screen was cracked but undamaged areas still work and show some image, you can use it to test the laptop.ĭisconnect the new LCD and install the old damaged one back in place. OK, you have reseated all cables but it still doesn’t work. Be careful, they are very fragile.įortunately, most newer LCDs have a different type of connector, without any pins inside. You can straighten bent pins with a very small screwdriver. It’s possible that you accidentally bent them while trying to plug in the cable. Take a look inside, make sure there are no damaged (bent) pins. Some older LCDs have very thin pins inside the video connector as it shown on the following picture. The video cable has to be seated properly, all the way down into the connector. There is a chance that now the screen will work properly. Reconnect the cable, secure the connection with sticky tape and test the laptop. It’s possible that during the reassembly process you accidentally pulled the cable from the connector. If your new screen lights up but has no image make sure the video cable plugged correctly. The wider end connects to the screen (supplies data signal) and another one to the inverter board (supplies power for inverter). Somewhere close to the hinge, the cable splits. The video cable routed from the motherboard to the display through one of the hinges. On the following picture you can see how the screen connected to the laptop. The old style screens have a backlight lamp inside and require an inverter board which is usually mounted on the lower part of the display assembly, as you can see on the following picture. Troubleshooting LCDs with CCFL (backlight lamp) Double check the compatibility between the original and new LCDs. If the screen looks identical, it doesn’t exactly mean it’s compatible. First of all, I assume that your new LCD is compatible with the original one.
