Oh dear,It looks like you might have a faulty CCD image chip this is immediately behind the camera lens.
put the camcorder on record standby if this is the case you will see the blue spot in the Lcd monitor
The fault could be dead pixels, the ccd chip has millions of
red green &blue pixels in it.
You will have to get it looked at by a camcorder engineer
from JVC..
