Does anyone have any advice on acquiring replacement screens for the TI series? I was considering buying broken TIs on e-bay, but that may be unreliable.

Fixing TI83+'s is becoming addictive. Google Cemetech Forum on the net and see how he removes the screen from the Mother Board and solders wires permanently. I might add that he tests for resistance (ohms) first to determine if in fact that is where the problems exist. If I read between the lines, he tends to think that the screen/mother board ribbon cable is the primary culprit behind problems with the TI83's

It may not be broken. Try adjusting the screen contrast down.
