    a2251 eDP lines dead

    Hey guys,
    I have this display connector water damaged.


    PP5V_G3S_ALSCAM_was corroded, not the other side where lcd backlight is.
    nevertheless, EDP_INT_AUX_N and _P both have .0l in diode mode (not shorted to ground)

    I fixed the alscam line, restored laptop via dfu. I get chime but no image on internal and external display using type-c - hdmi cable (not the original apple).

    I tried displays from a1708 and 1706 but the result is the same(I do not have another a2251 display on hands).

    Question is should I try to find a working a2251 display or this is 100% dead eDP line?

    If so, if I take the cpu from a locked donor board, will my clean IC remain?

    I am asking this as I am not quite sure where ic lock lives, in T2, NAND, CPU

    Thanks!

      Screen Display Vertical Multicolor Lines
      by Stanley1843
      Hello, I have a screen in where sometimes when I open it pop-up vertical multicolor lines (I would say the most of them are green). If I tun off and turn on the screen the lines dissapear or if I leave open the screen after approximately five minutes the lines gone. I measured the below voltages on the main PCB and on the T-CON board and the voltages are the same when it doesn’t display the vertical lines and when it displays the vertical lines. Also, I cleaned all the connectors very good with IPA. I moved back and forth the connectors and the COF tabs but the vertical lines didn't displayed...

      How can I be sure that my EC chip is dead?
      by double_DD
      Hi all,

      As the title suggests, how can I be sure that my EC chip is really dead?

      I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.

      Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard...

      Samsung QN50Q60t lines on screen
      by jeyoung12
      Hi all
      I have lines on the screen...which is an age old problem that can be remedied by watching Youtube videos and getting out the tape.
      My issue (after successfully fixing a different sammy tv with a separate tcon board and isolating the side of the panel...):

      This tv has an integrated tcon...so it is a bit more confusing when trying to isolate the clocks.
      It has a c ribbon and i have taken each end out to see if that will isolate the lines. instead, it makes it much worse ALL over the tv!

      So....i don't know what end of the C ribbon to work with...

      Sharp (Hisense) LC-55p6050u - Flashing/dimming row of pixels
      by DrvLikHell
      Hello again! I have come back for some wisdom and hopefully for some guidance with this problem I'm having. The TV is a 4k 55" Sharp LC-55p6050u and the problem is every other line of the bottom 32 lines flickers out, comes mostly back, then flickers out again, and repeats this continually. The lines on the bottom right of the screen go out completely while the lines on the bottom left are affected so slightly that it's almost impossible to see it. There is a gradual gradient from appearing almost perfectly fine on the bottom left, to an obvious problem on the bottom right.

      The...

      Samsung QE50Q67TAU - horizontal lines
      by Rubenlily
      Hello,

      First of all I'm new here. While looking I found this amazing forum and I'm very happy I did. Now for my problem:

      I picked up a Samsung UHD QLED QE50Q67TAU from 2021 for $50 knowing it was defective. The seller said it had black lines and that it could get stuck in boot randomly.

      I've tried a new power cable, hard reset, opening up and jiggling all cables, pressing everywhere to see if I get a reaction but I've gotten nothing. I've tried the tape method but I've only managed to get the lines worse.

      I'm no expert but I've done the tape...
