    LP156WF6 lcd screen

    I didnt repair led/lcd screens before from laptops...and to tell you the truth it was very rare that they were not working; either i got them broken or damaged lcd cable...
    But now i have three LP156WF6 lcd screens with same symptoms...(different laptops) There is no short anywhere...all fuses are good and on lcd board coils i have 19v and 3 volt...nothing is getting too hot...but no picture and backlight. I checked with working screen and those laptops are posting picture, so this lcd-s are definitely dead.
    My only conclusion is that the chips (i believe there are 2) on lcd boards are dead or something...and i have a few of similar broken screen lcd-s for chip replacement but i want to be sure that is the problem?! someone here more experienced in lcd screen repair? any advice?

      Trace the cable end on the display. There should be a T-con board. In the past, have had good luck repairing these on the iMAC displays. Found shorted caps onboard. You can review the caps for their resistance, with no power of course. Otherwise ask some of the vendors that sell T-con boards on AliExpress for assistance. Mention this lcd panel. Just some ideas to explore.

          Post the full laptop panel part numbers such as LP156WF6-SPB1 , LP156WF6(SP)(K5) .Do you know what laptop models each came from,a few years ago there were some problems with win 10 and nvidia drivers bricking the EDID firmware.I posted some links to a thread at notebookreview which discussed the problem and fixes. https://www.badcaps.net/forum/showthread.php?t=76270 sadly notebookreview is no longer but you can use the waybackmachine to view the archived web pages https://web.archive.org/

              iphone XS turns off when press on screen.
              by smic717394
              Hi,

              I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...

              Vizio TV M50-C1 reboot cycle and static on screen
              by spice_disc
              I'm currently trying to diagnose and fix my Vizio TV (Model M50-C1). I've tried a number of different basic solutions, but I'm trying to determine if my issue is currently a failing panel, T-Con board, or main board (or something else entirely) and whether or not it is worth my time to fix it. Details of the issue and what I've tried are below as well as why I think it is either a bad panel, T-Con board, or main board.

              The Issue: The TV will be on and working fine but after the TV is on for ~5-10 minutes the screen will freeze (with sound continuing) until the TV reboots itself. While...

              ipad pro 9.7" blew a SMD component while replacing the screen 🤦‍♂️
              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,...

              Trouble to identify part (Lunii screen) for replacement
              by FreakyMex
              Hello guys. I'm a complete noob in electronics. I'd like to repair my child Lunii's (a "story box"), basically an audio player that allows the childs to choose between several options the places, characters, objects of the story, and then play a story according to the choice of the child. There is a screen that display the selected option before each choice. The Lunii fell and the screen is now broken.
              I'd like to repair it (probably just have to change the part, because the lunii still works perfectly fine) but I can't manage to identify the part/order it online. Do you have any...

              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...
