    MacBook Pro A2159 - No Display / Works on External Screen

    Hi,

    I am working on a MacBook that came in for a screen replacement. The MacBook powers on and works on the external screen. However, the screen stays black. The replacement screen made no difference. On further investigation, I found small amounts of corrosion.

    Please see the attached image.

    I ordered a refurbished logicboard, but the problem didn't go away with the old or replacement screen.

    Can anyone suggest where to go from here?

          Start with IPA onto this device & cotton swab / Q-tips to remove the corrosion. Allow it to dry. Test again.

          If still no go..

          Apply flux onto this corroded part -> low air pressure but high heat. Allow the solder to melt and use tweezers to gently nudge the component that should bounce away and reset back onto the PCB pads.

              MacBook A1990 vertical stripes on external screen
              by ahoonid
              Hey everyone,

              I bought a MacBook A1990 with no screen. I bought it knowing the motherboard was defective but wasn't sure what the problem was until I received it. It actually turns on but as you see from the attachment, it has vertical stripes, on an external screen!!

              The board is neat. Not opened before for sure. Just a little dust, nothing more.

              Recovery using wifi can be opened, as can also be seen in the photo but it doesn't go all the way through after connecting it to a wifi. It downloads the initial Recovery files but never completes the rest of the...

              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...

              Acer Nitro 5 AN515-54. displays on the external monitor and works fine, the issue is NO display on the internal screen
              by DqMagetz
              Good day!
              I have a customer's laptop — Acer Nitro 5 AN515-54 (EH5VF - LA-H501P). It has a display on the external monitor and it's working fine, but the issue is NO display on the internal screen. I already replaced the eDP cable and checked the LCD connector pins.

              Here are the voltage readings:
              • Input – 19V (stable)
              • +LCDVDD – 3.3V briefly, then drops to 0V
              • EDP_HPD – 3.3V briefly, then drops to 0V
              • PCH_BKL_PWM – 2.2–5V briefly, then drops to 0V
              • EC BKOFF# – 1.8V briefly, then drops to 0V
              • PANEL_OD_EN – 0.3V

              Is it possible that the EC chip is corrupted or damag...

              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 A2337 (820-02016) USB-C Port Issue – Only Works in One Orientation (CC Line Problem?)
              by rounin
              Hi everyone,

              I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.

              🛠 Original Issue
              The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
              Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.

              I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.
