A little bit about me and myself

Been loving electronics since the age of -3 months. Was born with electrical short on my heart, but the Drs were able to save me and fix the 19V Rail.
Since I remember myself, I loved taking apart electronics, and test/ repair/ understand how they Work

I'm here to explore new ways and ideas of other techs on how they start working on a problem and getting to a solution...

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...

please see attached pics...

Hi all,

I'm new here, trying to get some help with a repair
We found a short on the PPVDD_GPU

I want to hope it's only bad capacitors, the attached pic shows the short area
Getting 0V on all caps marked in red

Other areas of the board seem to get the correct Voltages

Can I assume the problem is with a burned cap?
Will try to send direct Voltage to a cap in the circuit and check what gets hot first

If we find a bad cap and replace / remove it, and assuming problem consists, what would be the next step...
