iPhone 3g screen woes

hello guys, can tell first time posting here.

on issue phone. woke 1 morning made call, , proceeded place phone down on bed. came @ 20 minutes later, find screen had turned white. after seeing not respond of prodding, forced restarted it. though screen no longer white, black. still received calls/texts/ vibrator worked, , still forcibly restart or shut down. tried restoring/updating. ended making appointment @ genius bar, , while there told water damage, , 2 stickers should have been white red. shocked when heard this, because believed issue had nothing water.

should noted have had phone 2 years, , have never had case on it. screen faultless except 1 minor scratch on side. 'genius' proceeded tell me have happened several years ago, , phone suffering effects. while won't rule out, because crazy things happen. chances extremely slim, , never remember getting phone wet enough point effect anything. believe few drops of rain cause of stickers changing colors, , phone has come contact liquid substance.

again guys, chose come forum, because general populous seems astute.
