Mac desktops forum: IMac only works if I use external monitor

That makes sense if I had made changes but I did not. that is not to say that an update didn't. The cost to just pick this or that piece of hardware to replace seems a little drastic and not very methodical and logic based. Has the industry changed where there is no real way to determine what the actual cause of a problem is? What you are implying is that if the car doesn't start put in a new engine or if it doesn't start sometimes put in a new fuel injection system or gas tank or starter. In the auto industry their are test that will pinpoint what the problem is and for those who make their living at it can narrow it down closely before pinpointing specific test to get to the actual problem. It seems that the equipment needed to properly test specific hardware part or the transistors on a board are not available or not use preferring to throw out a perfectly good computer, like mine, or replace large expensive parts until the problem stops.

If that is a valid description of where this industry is then buying on price with extended warranty of 3 yrs (Dell offers 5 now) knowing that it goes in the trash when the warranty expires is the only path to choose. I paid a lot more for the Apple name then I can ever justify again.

What are your thoughts.
