Lense Cap Error

My recorder says "lense cap" when the lense cap is not on and the viewfinder stays dark. Is there a way to repair this or a reset that I can do?

This problem is caused by a stuck aperture assembly. The problem has occured on multiple models made by JVC (GR-DF430u, GR-DF450U and GR-DF470U). You have to have some degree of technical aptitude in order to disassemble the unit and access the part causing the problem. The tiny motor that opens the aperture flaps is not able to overcome the sticky oil/grease that JVC unwisely used on this part. Therefore the flaps stay closed, and the camera sees no light when you remove the lens cap. This makes the camera think you haven't removed the lens cap, causing the "lens cap" error.

If you feel like you have the skill and you are careful, you can disassemble the unit and clean the part yourself. It takes longer to take the unit apart and put back together than it does to clean the sticky oil off the part.

If you contact me, I can send you a diagram of where the part is located that you need to access. This is not recommended for amateurs, as you can damage the unit and cause other problems if you aren't somewhat skilled in disassembly of electronics.

Could be sand particles getting into the seams around the lens barrel, binding it up. Unfortunately, many cameras that fall prey to lens error problems can only be corrected by professional repair. But, here are some last resort troubleshooting steps that you can try that may correct it. They only seem to work for less than 40% of the lens errors, but if the camera is out of warranty (or repair cost approaches that of the camera), they're worth that try.

No image displays on screen or in view finder. Lense cap is open.


Try the following link if no picture or a black screen appears in the viewfinder or LCD when attempting to record.

Lens cap?


Try removing the battery, wait 30 seconds, and plug it back in. That may reset the lens cap sensor.

If you're getting the 18-4489-957-000 error code, then give it a good tap on the corner where the lens cap is. A little tapping and the lens cover should pop closed. When you turn the camera on again it will probably work just fine.

I was just about to junk my camera when I googled the error code and found this very tip in another thread. It worked like a charm.

Panasonic DMC-FZ7 digital camera.


I believe the FZ7 determines that the lense cap is still on when it can't extend the zoom lense because the lense cap is in the way. I would check to see if your zoom lense housing is somehow stuck (could be sand or dirt in it) which is creating enough resistance to make the camera think the lense cap is impeding the zoom lense from extending.
