:: Sony alpha A55 image error

for some strange reason, i noticed my SLT camera having issues with resolving the image properly, and i was right. it seems after firmware upgrade to ver2, the camera needs a system reset just like a computer.

can you spot the image error (it is difficult to see, but it is a small orange dot, and it always appears in every shot except the error-free shot)? 1 of the image seem to have a higher resolving power after a soft reset.

the bottom image is the 1 with the problem, the orange dot is on the lower edge of the black SMD chip.
