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

Nothing is broken, the screen has turned Black, need to send it off and have it fixed, I can not do it my self because of the condition of my hands

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

All I needed was to know the T6 Screwdriver size, the carved-out screw-holes made me less worried about the bits of plastic coming out of mine. Thanks!

Is it uncommon to have an aluminum sheet attached to the piece of paper with the battery markings on it or is this just me?
