Analysis: If there is no WiFi, first measure the voltage at C5202_RF; it should be 3.8V. If not, connect a wire from another point to C5202_RF, then measure C5204_RF for 1.8V. If that is also absent, short R5208_RF, check and replace L5201_RF, and replace the WiFi module at C5202_RF! If the WiFi signal is weak, … Read more
