taking @ friend's broke imac - white 24" - can't place model. emc 2111 best can pull off case. entering serial @ apple says 24" imac, no year, nothing.
after tons of testing i've figured out following...
1. screen boots grey, apple logo spinning loading circle, light blue. cursor stuck in upper right hand corner. screen stays blue. there's visual artifacts on screen - stuck pixels.
2. got bright idea plug in external monitor. once booted see lit black screen pixels artifacted, they're stuck - not 1 or 20 or 50, 100s, maybe 1,000. can move mouse cursor screen screen. cursor stuck in upper left hand corner of imac built in screen still stuck there.
3. external monitor plugged in can make os x make error *dong* sounds. i'm assuming i'm booted os x , looking @ desktop video card refusing refresh/display graphics.
video card dead / dying? suggestions? don't have installation media boot , attempt hardware test - typing refurb lion came 0 media. attached photos: blue monitor imac, black = external.
