Hi everyone
water damage at the following locations:
connector J3300 and its surroundings
R2890, R3098, U2890 visible signs of overheating on the cover
after connecting the meter to USB C 5.1V 0,3A,
damaged part U3100 (CD3215A10 it has such a designation in the diagram, CD3215C00Z such a marking was on the damaged element, CD3215B01 such a marking is on the element that I soldered) This change does not have a negative effect on performance ?
after replacing the heating element(U3100), it looks like a hare 5,1V 0,24A
diode test with a red court on ground
F3000 0,132/ 0,718 kΩ
F3010 0,132/ 0,721 kΩ
what should i check next ?
