Sony digital video camera Model: GR-D30U

This is usually caused by a defective CCD image sensor and can be repaired fairly inexpensively. However, it's not a user serviceable problem and will need to be repaired qualified service technician.

Your camera lens has a problem. If you have background repairing such. Try to open and clean the iris curtain(shutter) with methyl alcohol or any other alcohol base cleaner. Must be open and bring those curtain out to clean it effectively. Otherwise have it checked by JVC Service Center near you. Good luck

I want you to do this to confirm which part has a problem. Look at your camera lens directly face to face and observe those tiny shutter inside while switching on your camera. You must see the movement of those tiny shutter and even hear some clicking, if so, CCD replacement is needed. Sometimes those shutter stacked up and shows the same symptoms. Hope it helps

Replace the CCD base Assy on the optical block assy.

Hi,
It is known problem of bad ccd imager in JVC GR-D30U camcorder.
JVC will repair it free of cost. Please click JVC CCD Imager Support for details.
Thanks.

The internal iris is probably stuck closed. This is not a repair for anyone that has not worked on cameras before. The lens assembly must be removed and the iris section dis-assembled, and cleaned. Once that is done, it must be re-assembled. There is a possibility that the iris control motor is bad too. You can try tapping the side of the camera close to the lens area to see if you can free the iris, just don't hit it too hard.

Keep us posted.

See my post of before. I just knocked the camera on the floor by mistake and it miraculously started working again after years. Shows it must be mechanical and not related to software.

is the camera still recording? still working fine? if so then there maybe a switch or sensor that is bad..

Assuming you don't see any video through the viewfinder, it could be that the CCD has died on that camcorder. It happens, though not frequently.

If the video though the viewfinder is clear, there might be some sensor on the lens ring to indicate a lens cap, or an automatic lens cap not properly disengaging when put in record mode.
