I have just purchased a JVC GZ-MG505 camcorder (not long introduced into UK).Worked fine for a few weeks, now I find that the LCD suddenly goes blank,about 10 - 20 seconds into recording; the Power/Charge red light begins blinking and despite switching off the power keeps on blinking. I have to remove battery to get the light to go out. Recharged battery and tried again, same happens all over again. Any help advice would be gratefully appreciated.

I bought a JVC GR-DF450U and have hardly used it.  The other day when I turned it on, the LCD screen and viewfinder were both blank.  The cap is off and there are no errors on the screen.  All of the functions work but I can't see anything on the fold out LCD or the viewfinder. Need help!!!Fast got a vacation coming up!!!

Thanks for your help. i tried tapping the iris and it stlii just a black screen.At first it says lens cap is on but it isn't on. I have only used this camcorder maybe twicw, but it has been sitting for a few years while I was deployed. I know the warrenty is up,Need some help!!Wife not happy!! Any other ideas??

Can I take it apart and try to get it unstuck or repair it myself?

Sorry about the late entry, I've been away.

The problem described here is relatively common and can be repaired. Usually if hte shop has any experience with these cameras, the cost will just be the labor. No parts are required for this repair. Basically what happens is that a small amount of lubricant has gotten onto the iris parts. Since these are usually controlled by very small motors and springs, it doesn't take much resistance to keep them from moving. The "repair" consists of dis-assembling the optical section to expose the iris and cleaning the iris parts themselves. Once cleaned, the section is re-assembled.

As Larry points out, this is not a repair for the novice. Camcorders are difficult even to the expereinced tech. On the good side though, usually once this procedure has been completed, you should never have the problem again.
