1 Screen Black Out, otherwise perfect
Hi,
I have searched the forum for this issue, but can't seem to find a similar problem.
I have an iMac 17 iSight. No issues with vertical lines, dark areas or funny colours. The issue I have is that from time to time, well it's getting more frequent the screen will go black, the computer is still running and I can here volume increase noises and so on.
To counter this I attached a second monitor, which worked well, but now this is playing up and going black, I have checked it on another mac and its fine, the mini dvi is also fine.
I can gather that both screens are turning off at the same time, not separately. So the iMac is suddenly losing its ability to show the screen
Is this a graphics card issue, lose connection, something I can fix, I have reset PRAM, SCU and everything else I can think of.
This is not my main machine, it has Skype on as we'll as Office and hats it, so it's not being overworked.
Anyone had the same issue, as I said the screen is vibrant and clear....
Ist dies eine gute Frage?

if both the external and internal monitors exhibit the same symptoms, it is most like a graphic card issue. What are the last three digits of your computer?

For some reason unknown, the serial number is not getting us what we need. Please look on the bottom of your stand and get us the EMC # and processor speed. Thanks
