is there posibility to test Nokia displays using just power supply?
i seen boxes that can check different Nokais displays, but i didnt see any schematics exept 2 or 3 wires from ext. power sypply?
if it is possible so what voltage must be and what pins(signals) are using?

SVH,

power supply only is not enough, you have to give "reset signal"
and data to init. it too !
