Your model almost certainly has the well known "lens cap defect". If you reply to this entering your e-mail address in the box provided (only seen by myself!) FULL info will be sent on.

I have the same focus issue with my JVC GR-DVP3U. Manual focusing also didn't work. I took it to a JVC repair facility here in Chicagoland. Where they said they would only look at it if I paid them first. They charged me 50.00 and said they couldn't replicate the error. That there was nothing wrong with my camera. I don't even think they opened it. Meanwhile I get it home and it's still broken. Still won't focus. Lying morons. Repeat after me, "I will never buy JVC, ever again!"
