Re: Ayaneo 2021 pro short help
The cpu has southbridge which is connected to pd controller directly,probably when chip died,it has taken cpu with it...it is such design...that is me thinking loud...Leave a comment:

Re: Xiaomi mi 9T missing resistor
Yes,it must have continuity,just put some 0ohm with same size on boardLeave a comment:

Re: Ayaneo 2021 pro short help
In the meantime i removed rt3663bm chip,"short" is still there on traces that lead to this chip pin24&23...In manual says :23 Over clocking offset setting for the VDD controller.
24 OFSA Over clocking offset setting for the VDDNB controller.Leave a comment:

Ayaneo 2021 pro short help
Hi,device had removed usbc pd driver chip cypd5225 because it was hot,when i got mainboard i connected it to usb charger to test,and after 2-3 tries HP8K24 chip got fried.main voltage was ok(it is ryzen 7 4800u console with 11v battery).Im not very familiar with this design,but after long time i found short on rt3663bm chip on OFSAA( pin24 & 23(resistance to ground0.4ohm),which is doing overclocking through NB of CPU.I have pulled all coils,but
lowest resistance to ground is 3ohm on cpu side...Is cpu dead? -
Re: Asus tuf FX505du charging,but wont power on
Yesterday i was measuring this cap near mosfet(this blown is 4 in row) and 3rd one had 2.7uf,is this my MM wrong,i even measured it out of circuit and again the same...is this 0603 size 4.7uf/6.3v?And L3603 is 3603 size 120ohm 100mhz(this one i surely can't measure cause i have aneng m118a)...jeezLeave a comment:

Re: Asus tuf FX505du charging,but wont power on
Thanks Sephir0th,i could not do it without U'r help...can i salvage such resistor and cap ,or i need to buy...because in circuit resistor has short ohm reading,maybe remove it then measure?Leave a comment:

Re: Asus tuf FX505du charging,but wont power on
Well,i have no bench Ps so i improvise with 1volt battery about 1 amp,but nothing gets hot...3v battery would not be good idea?Leave a comment:
