I was unable go get into any of the archives:
http://www.piclist.com/techref/postbot.asp
http://www.infosite.com/~jkeyzer/piclist/index.html
http://www.iversoft.com/piclist/
 
A search of my own personal piclist archive didn't yield a result.  Please
forgive me is this question has been asked before.
 
I was recently working with a vendor that supplied equipment where the small
LCD backlit display would periodically either go dead or display garbage
characters.
 
After trying replacement displays, controller boards for the display, and
power to the unit, the vendor had me put a Ferrite block around the 5"
ribbon cable going to the display.  It, of course, didn't have any affect.
 
My naive questions:  Is the vendor just "grasping at straws"?  Has anyone
had success using RF suppressors on short ribbon cables leading to LCD
displays?
