Well, what I mean by the cel's root problem, is 
the problem that's causing whatever it is that's 
wrong with the cel.  In my case, the line 
fading.  They find out why the cel is fading, and 
treat that problem.  Say if the cel has had too 
much moisture, they correct that..I think.  Sort 
of like when you go to the doctor with a disorder 
or disease...they want to find the cause of the 
problem and treat that, not just cover the 
symptoms with medicine.  That booklet was soooo 
in depth.  The stuff they do is just, I couldnt 
even read it all. But if you arent willing to pay 
over 100$ for getting the cel fixed, then yeah 
it's not worth it.  There are some other places 
than can fix damaged cels for less, they just 
dont go as deep into the problem as this place.  
Either way is cool :).  Im sending a low dollar 
cel to another place, as a guinea pig :).  I need 
to post the pics in that booklet though, of the 
before and after restored jobs that SR has 
done..you'd be shocked.
