you're right.. now it works! Thanks Eric!

with the new firmware, no problem, I use it before important shots and when I see dead pixel.

After many times I used to mark the defect pixel, the service-menu now never works!

I push display button, power on - hold focus-assist and menu - the only thing I can see is
Firmware-Upgrade ready and the Cam don't show me the advanced-menu.

Some month ago, it worked fine, but after one year work with the Cam, the trouble begins.

The solution is, I must push the buttons more slowly, then it works.

Hi Eric make sure your cam is setup to 720p and 60p otherwise the hidden menu will not work like in 50p

Guide to fixing stuck pixels from JVC Technical Support
 

I recieved this handy, clear and useful PDF to explain how to fix defective pixels on our CCD's from JVC Pro Technical Support here in Australia. It's even got pictures! :)

Super handy resource that I wanted to share with you all.

you must push your buttons slowly, not at the same time
