Video of how it reacts on each port https://streamable.com/z9mcly

Ok so at This time i have ONLY one port that switch to 20v (u3100) this is the right side! in the schematic u3100 is primary and u3200 secondary The other have All the same voltage and all the same amp (5v@0,270) I would like to start from the right side, the side where i have 20v… What Could...

resoldered back ub300 and ub400 now i have again [email protected]

I swear: i’m going crazy!! You said “OL means no connection; broken trace, or bad solders.” So i have removed ub300 reballed and resoldered…and now the ports to the others side, stuck at 5v@1amp! (Even the port that was switching to 20 V😭) So i have Removed both ub300 and ub400 The the port...

ok with the third cd3215, now i have 1,8 on c3206, but u3200 doesn't switch to 20v, u3100 yes! 3V3 on [p:C3208:1] 1V8 on [p:C3205:1] 1V8 on [p:C3206:1] 1V1 on [p:C3204:1] all presents

so i have problem on pin 33 40 42 right? i have Ol in diode mode checking directly on the connector... pin 30 is USBC_TA_USB_TOP_P and i have ol... so if ol is not correct, i should read something on USBC_TB_USB_TOP_P right? but i have Ol i have 2,5v instead of 1v8 on c3206, how is it...

I can’t find an explanation https://ibb.co/w6KPBjp https://ibb.co/r5D9MWT Do you have a 820-01041 to check in diode mode the connector ??

U3100 is the chip that switch to 20v According to This usb type c tester, i’ve discovered that on the ports that doesn’t switch to 20v, i have wrong value on pin 6/7/18…All 3 ports, same wrong value on same pins You can see the values on the port that switch to 20v https://ibb.co/gSqW21y...

NO! the problem at the beninning was NO BOOT, 3 PORT AT 5V, ONE PORT TOTALLY DEAD because of a small journey, i've ask a friend of mine to chane ONLY THE USB - of the broken port. don't ask me why but, he has changed all usb ic of the ports...so i have had 5v on all ports.... so i have done...

Let’s try to start AGAIN 4 ports/4 brand new cd3214 1 port switch to 20v, the others 3 rest to 5v How to go ahead?

“820-01041 no liquid spill...3 usb ports stuck on 5v, the other port totally dead Because of a small journey, I’ve ask a friend of mine, technician, to change the controller corresponding to the dead port I don’t know why, But it has changed all 4 controller” yesterday i have changed with...

i don't understand what i'm doing wrong...i have all ldos on xb, but i still have 5v...

so one port can switch toi 20v...port XA!

ps is it normal that i have not resistor r4807 and 4808 in the board? i have 2ohm resistence on la650 la340 la7231

so i have changed again all 4 ic with 4 brand new. i have check for short every pad, before soldering each ic. i have soldered the first and checked with ampmetere [email protected] i have soldered the second and checked with ampmetere [email protected] i have soldered the third and checked with ampmeter...

i have not other boards with me :(

ok just a question.... like i said , i have changed all 4 cd3215...but they where used... now i would like to mount 4 brand new ic could i mount 2 at times? i mean ta / tb...test if ampmeter power on then xa/xb and test? ps do you know where can i find resistence to ground for the pads...

yes sure, but you have asked me to check all coils in diode mode using referance table...in the reference table there is no reference to diode mode for the coils, but for the lines!!! "If T2 gets all SLPS2R and AWAKE required voltage" i don't know this voltages....could you help me? 3,3 on...

found pad spi_cs0_l interrupted after i have fixed it, macbook has start working !!

hi to all...i have this motherboard with orange ligth. connecting it to my power supply (15v@3a) i have a bootloop like 0,022 0,0055 0,0015 After testing all the power aliases page i think I am missing my S0 enables which looks like I need PM_SLP_S3_L PM_SLP_S3_L is 0v ,the line is not...
