Is this procedure good for replacing the backlight of the cluster panel?

Does anyone have information (possibly in a pdf file) for repairing the instrument cluster lights in a 1993 LS400. My display is completely black though the needles do sometimes light up (at random!) and the gas gauge and odometer come on when they feel like it. After visiting several junk yards in the Chicago area I realize that used ones are extremely hard to come by. I am on a very low budget. Please Help!!!
