Display problems with Surface 1872
Hi, I hope someone can help me here. I was given a Surface 1872 with a broken screen to fix. The picture was viewable but yes, the screen needed replacing. I cleaned out the broken screen and bought a brand new one (that was a mistake that I won't make again !!), I then attached the new screen in place of the broken one (not in the lid, just laying above it) and attached it using the 4 cables. The laptop booted up, but there was nothing showing on the screen. I attached a USBC cable and plugged it onto my Monitor's HDMI port and that screen was fine. I then, by accident, touched the laptop screen and bizarrely, the touchscreen was working, just only visible on my monitor, not the new laptop screen. Googling this told me that it was probably a faulty screen. I then bought a second hand replacement screen, apparently tested and fully working, but as part of the whole top, i.e. in and attached to the lid. I replaced the laptop screen again and this time there was still nothing on it, but my monitor showed some flickering & some lines. I therefore disconnected the screen re-attached all of the cable again and rebooted. I hear the laptop boot up, but now I am getting nothing on either screen !!! What on earth could have caused this ? Why, at least, do I not have video on my Monitor when I did before ?!? I have tried CTRL-Win Key-Shift-B & numerous other suggestions but nothing has so far made a difference 😢 ... Any help or advice would be a Godsend !!!
