Aperture shift NG
1>. Check if lens connecting board contact NG,
cold solder or insufficient solder, remove the
abnormity;
2>. If (1) is normal, check if R80, R81, R82,
R83, R85, R86 are cold solder or insufficient
solder, remove the abnormity;
3>. If (1), (2) are normal, check if CN1 and CN2
contact well, remove the abnormity;
4>. If above items are normal, check if U8 and
related circuit are cold solder or insufficient
solder, remove the abnormity.
Lens focus failure
Check if lens and around components are
normal; remove the abnormity.
Lens resolution
issue
1>. Check if CCD is assy well, remove the
abnormity;
2>. Check if lens is NG. Change lens
Lens noise
1>. Check if lens is NG. Change lens
2>. Check if the components around lens are
cold solder or insufficient solder, remove the
abnormity.
Power on failure
(without current)
1>. Check if the connection between MCU
panel and soft connecting panel of Shutter is
NG, remove the abnormity;
2>. Check if the fuse F1 on power board is
broken, remove the abnormity;
3>. Check if crystal Y3 is short-circuit, cold
solder or no solder, remove the abnormity;
4>. Check if the POWCTRL related circuit is
cold solder, insufficient solder, short-circuit,
component broken, and etc. Remove the
abnormity;
5>. Check if the related tube pins of U11 are
cold soldered, insufficient solder, no solder,
short circuit, and etc. Remove the abnormity.
Power and
system
Power on fail (with
current)
1>. Check if the connection between MCU
panel and soft connecting panel of Shutter is
biased or NG, remove the abnormity;
2>. Reuse the USB update FW, confirm if the
camera can power on;
3>. Check if U10 is cold solder, no solder or
insufficient solder, remove the abnormity;
4>. Record U10 again to confirm if the camera
can power on;
5>. Check if S3.3V is normal, remove the
abnormity;
6>. Check if inductance and audion on power
board are cold solder or short circuit; remove
the abnormity.
