Hi,

I've a iMac 24" and I would like to resell it urgently.

But I've a big problem, if I disconnect my second display (belinea 20"), the iMac screen become grey or blue after many second.

If I boot system, after the grey clock : nothing, grey or black screen.

The Os is snow leopard disc, update version (10.6)
The iMac version is iMa8,1
The EFI bios is : IM81.00c1.b00

I tried :
Reinstall with format
Utility disc on boot cd (scan disk & rights repair)

Even when I try to boot cd without second screen, I ve white screen
(after a update to 10.6.4)

Help me please

MacPro4,1, HD4870
