Hey everyone...my iMac is giving me some grief! A while back, I started getting flickering on the screen as if it was trying to adjust for the light or something like that. It'd flicker a few times and then stabilize and you could go about your business. That continues. It's more of a nuisance than anything. But that's not the real problem (although it's probably an indicator) Now, at least once per session, the screen just ups and goes completely black; turns completely off. Be patient and wait about 15-20 seconds and hit the power button on the back of the iMac will turn the screen back on and you can resume life. Now here in the past few days, both are progressing. The brightness of the screen almost continually while in use, flickers in intensity and the complete blackouts are getting worse. A few times, the power button trick did not bring it back. Had to force a shutdown and unplug it and walk away. Then a restart would eventually bring it back. Certainly seems like she's on her way out. But the colors on the screen are working and the computer itself is working and functioning completely normal...no problems at all. Am I looking at a new computer or is this something that can be addressed??? Where can I take it/send it for this problem? Thanks everyone!!
