3. Image Is Blur or Can Not Capture Image Testing Procedure
A.Please check the wave of pins on
U11(CMOS Sensor) with oscilloscope by
power supply .
If the wave is different, please replace U11.
B. Please check the wave of pins on
U13(SDRAM) with oscilloscope by power
supply.
If the wave is different, please replace
U13.
C. Please check the wave of pins on
U14(Flash Memory) with oscilloscope by
power supply.
If the wave is different, please replace U14.
D. If the image is still blur or can not capture
the image after check the wave of pins on
U11,U13 and U14 with oscilloscope by
power supply.Please try to replace PCBA.
