Hi, I have found out how to get to the "TEST JC" graphic on my JVC 723 GD. I even know how to get the blue light up (JVC reset info) but I have no idea if it is possible to region hack from here.

If you own the beast can you try?

Instructions are easy:
pull plug>
hold down stop + play>
plug in>
wait..
see TEST JC.....
...now you can play with the display button and get it to show you stuff....
To 'reset' press fwdskip then pause. blue light appears, pull plug and it is reset.

It sounds like if there is a hack I am close.
Any pointers out there.

Frustrated,
Greg
