    A2485 no image and no backlight after chip transplant on new screen.

    Removed the two chips from the broken lcd at 350C and 40 air by properly protecting rest of the area with copper and kapton tape.
    Did the same with the new replacement panel.
    Reballed the pulled chips and installed on the new lcd panel at 250C and 40 air
    I have done few ones before without issue.

    The new panel was working before I transplanted the chips. Now the computer turns on and boots but no image/ backlight. (
    Anybody face this issue before?

      I had the same problem on a device. Unfortunately it was not possible to return the original LCD as it was broken.
      Did you return with the 2 original chips that were removed from the new LCD? Have you tested? Did the new LCD with the original chips have an image again? Thanks

          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...

          Macbook Air M2 A2681 Kernel panics after screen replacement
          by reformatt
          Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".

          It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...

          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...

          Best place to source RAM chips? 8GB 820-00850 boards to 16GB or 32GB
          by ugamazing
          I'm looking to upgrade several 8GB 820-00850 boards to 16GB or 32GB for personal use. I am curious what the best practice and process is for sourcing new replacement chips, and what vendor(s) you guys prefer? Another question is, how do I find compatible chips and their corresponding part/model numbers? For example, in the 820-00850 schematic, the DDR chip U2600 model listed (EDFB232A1MA) corresponds to 1x32GB chip. Of course, I would need 4x8GB chips to replace the 4x2GB chips currently on the board. How do I find compatible 8GB chips? Is it as simple as searching "BGA178 8GB 2133"...
