I think i remember this happening to my VFX.
The user ram gets scrambled and crashes it when it boots.
Sounds like you need to replace the battery so that process will 
clear out the ram.
You will have to reinitialize the VFX after then it should work ok if 
theres no other issues with it.
The PSU's can be a problem on these, dry joints and failing caps.
I think i need to do mine as it goes..

lighting up....
