AHHHH. My 17 inch apple studio display has gone haywire. The power light is flashing (2 short lights and one long light) and half o the screen is dimmer than the ither. I tihnk it is the back light of the display. I bought this display probably 4 months ago, so it very new. its coupled w/ a 933 g4 w/ a GF4Mx. Is there anything i can do?? Thanks for your help.
