JVC GR-D70A

lens cap message?

Looking for assistance with problems aquiring picture in the LCD screen and through the eyepiece. At turn on a Lens Cap warning appears on the screen even though the lens cap may not be in place. The screen then goes dark , what appears to be a hand in the halt position in brackets is in the extreme bottom left of the screen and a yellow signal flashes in the bottom centre of the screen. This signal looks to be a human shoulders and head on the left with a mountain on the right and a between them. Has anyone any ideas- the camera although about 18 months old has done only three or four hours filming.

    I have seen this fault a number of times in my lab. The CCD imager is at fault, one or more of the tiny connecting wires comes adrift from the imager substrate. These wires are 10 microns wide (a human hair is around 30), and are part of the hermetically sealed CCD package. Repair involves replacing the CCD assembly & re-calibrating the electronics to match the replacement imager. Adjustments are made using software.
