open the machine, then turn on the corrosion, clearly visible on track and VTOUCH VLCD_3V.
try to clean the corrosion, the result remains the same, the total dead, hanging current 0.12A.
try to pry up one by one component corrosion, wash again with thinner.
check back via power supply, successfully .... condition of the phone is already on, the current begins to pulsate.
since the path VTOUCH and VLCD could not be saved, forced jumper of dots that emit the same voltage.
