hey guys,
Liquid damage around U7100 - U3090..
already replace r7021,r7022, r7105 with problem, fix trace pin 27,28 U7100 to c7120. also need to fix a trace pin1,r3088 to c3090!
Resistance on c7120 20ohm and 4ohm on c7150. i have another board fixed on my store and i noticed when i take 7021 pin 4&2 compare with a good board in diode mode i get "board non fixed" - 103v - "fixed board" - about 490v!! i think the problem is here.. but i cant find that, i check ther rails components....
the stupid think one more time is when i put a fake charger the fan spin!! also replace a q7180 for new one and same results!
any help will be appreciate !!
