Shuts off after one minute
It will not boot up completely. I have tried safe mode, apple hardware test. But get this: I removed the powersupply and checked visually and saw no burn marks. Diagnostic lights all come on. If I leave the lcd screen disconnected and connect an external monitor it boots up fine, but the fan is a lot faster, I imagine because of the temperature sensor not plugged in. What is up? I will not venture a new lcd as I have had a really bad experience on another imac in the past (brand new replacement lcd fried in 30 seconds after installing! $700 USD down the drain!). Could the mainboard be over heating but the fan going faster is compensating? Does not make sense.
Это хороший вопрос?

I have seen these Particular models have issues with the Cables on the LCD Displays. Sounds like that could be your issue. The Fan sounds like its only coming on after the LCD is not plugged in? Or is the Display plugged in and the fans are still blazing?

The display is not plugged in. But I thought I could hear the fan through the vent before I removed the lcd.

Hmm. The issue sounds like a Display. Even though you bought one before and installed it then it burned out within 30 seconds there could have been an issue with the Display before you installed it. Does the external Display not get any video with the LCD Display plugged in?

With the LCD plugged in the computer will shut off within a couple of minutes. I have not tried the external with the LCD plugged in.
