Question about JVC GR-DF450 Mini DV Digital Camcorder
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.
