    Macbook a2251 Water damage- stuck on Logo

    Hi all,

    Would appreciate your input, we have fixed a water damage motherboard for the a2251, there was mainly corrosion next to the 2 locations, but were able to clean it all

    First few times- the Macbook would boot and got to login screen (didn't try to login), day after, when we tested it - it would get stuck on the logo and won't show welcome screen

    What would be the best step to take from here to test? should I test Mobo components/ chip / storage? and if so- where do I start?

    OR should I try to use the Apple Configurator and connect it to another mac to test?

    The Macbook is not getting extra hot, so not really sure how to move from here

    Thank you for all help in advance

      Macbook A1990 stuck on logo
      by mr.Data
      Hello,

      This Macbook Pro 2018 boots up and then gets stuck on the logo.
      All the normal methods of resetting this Macbook have been tried but do not work.
      I cannot get into recovery mode and there is no bar displaying, it's just the white logo on a black background.

      Any help would be greatly appriciated....

      MacBook Pro A2251 820-01949-A stuck on 5V
      by mferna14
      Hi Dear friend., I am working MacBook Pro A2251 Logic board 820-01949-A. The history was that there was slight liquid on the LHS CD3217 & was not powering on at all. No 20v or any amps. I replaced with known good CD3217s & then got the power but its stuck on 5V .18amp. I did power measurements which are below:
      PPBUS_G3H=12v
      PP3V3_G3H=3.3v
      PP3V3_UPC_X_LDO=3.3v
      PPDCIN_G3H=5v ????
      PP1V8_SLPS2R=1.8v
      Do you think the other RHS CD3217 have to be replaced to as they might have gone defective????​

      Macbook Air 2015 Booting Very Slow and Stuck on apple Logo 99%
      by platinumsteel
      Hi guys i have my personal MacBook Pro 2015 820-00165 board that was working fine for more than a year and one day stopped working on my original Magsafe charger. It was turning on with my bench power supply. Opened it up and while diagnosing that somehow i ended up with a shorted smc.The line which was shorted was SMC_PM_G2_EN. I removed the SMC and short was gone. So all I had was another working donor board 820-3435 which i used to program it's SMC to 820-00165 using the SMCTOOL By MuertoGB.Took that SMC and use it on my 820-00165 board .And my board started working again. PPBUS_G3H 8.56V....

      MacBook Air A2179 stuck on Apple Logo
      by mferna14
      Hi all, working on a MacBook Air A2179 EMC 3302 stuck on Apple Logo. Came in dead. There was spillage on both of the USB-C Charge port connector. I replaced the cap 4.7UF 25V near the speaker connector as it was corroded. Replaced USB-C connector with a new one & now I get display. The problem is that gets stuck on the Apple logo & sometimes it even boots up into OS after a very long time & the CPU fan spins fast. Kindly any repair tips will be appreciated. Do these logic board have BIOS, so that I could do a clean up or load a new dump. Thanks in advance.

      MacBook Air M4 A3240 Brand New Water Damage no Image
      by Ugur87
      I have a brand new 13.6-inch MacBook Air M4 that was only used for three days and now has water damage. A glass of water was spilled over it. I examined the motherboard and there was only water next to the display connector. I cleaned it with isopropanol and the components look clean. The MacBook obviously turns on and draws 20 volts from the power supply. The keyboard backlight comes on, but the display remains black. Where should I best start? Even when I shine a light on the display, I don't see any image. I have all the tools I need, including an infrared camera. Where should I best start?...
