PPBUS_G3H was shorted... I inserted 2.0V on the rail, found some components hot, replaced all and the last one that was keeping draining amperage was the R5620 (When I took it off, the power supply came to 0Amp. I'm trying to find this Resistor from a donator board... rough mission, until now.
Hi friends, good afternoon...
I got a 16" MBP liquid damage and the mess was concentrated at the SSD region, front and back of the board... after some caps replacement, I'm having 5V at the ISL9240 but no PPBUS_G3H. When I plug the charger, it bounces from 5v 0.3amp and 5v 0Amp... Could it be a...
Hi Fam, good morning.
I have an 820-3332 which, after U8900 resolder, replacement, and all sorts of possibilities, was not completing the boot on any system, neither from internal or external drives.
So, I run the jumpers to bypass the dGPU and it looked perfect until I tried to run the...
Mine happened the same and I didn't find this blower in any other place than China and it was costing a lot and at least 30/40 days to arrive. So, I made one impeller using a 3D printer... it's still running for about 2 years with no problem... just a tip!
Hi, bud
USB has power BUT my external drive doesn't show any activity like LEDs blinking.

I got a 820-00239 that was liquid damaged and I cleaned up all the crap but, even if I leave just the battery, kbd, trackpad and display, it turns on the backlight but doesn't show any image...
I've replaced the LCD cable and stills the same
Any...
I'm back to work on this board... I stated that the R4802 lost its point 2 BUT it lost point 1 (PPBUS_HS_CPU). That's why I told you, it had a lot of other points on the board. I run a wire from this pin 1 to the other side of the board and the Internet recovery is now working and the computer...
Hi guys... The customer didn't care about the data, so I went to restore mode on the DFU mode... It appears to complete the process. The point is that, when I boot the computer holding option to choose and external drive, I can see my USB drive and, as I click on it to proceed, at same time it...
I've made the SMC Bypass and the computer loaded the previous User login screen. when I put the login password to proceed, the computer restarts and it's like an ever ending cycle again...
Looks like there's something messed on the T2...
Thoughts?
Thanks again
Hi Guys, good evening. I got from a customer a A1989 EMC 3214, board 820-00850-A and it suffered medium liquid damage, in my opinion. I replaced some caps and res, some other ones I just reflux and it's turning on now. The problem is it doesn't load the OSX until the end, even from Internal or...
