Yes its the same fault every time. The screen comes on for 5 seconds, then switches off, and stays off. (I have a back up screen). They say they have repaired the PC, repaired the screen, and I've had to replace all leads, without success.
I have a meeting with Apple tomorrow to discuss... The first time I returned the PC was September.
Ok thanks. Ill go to store tomorrow and see what they say. Thanks for your help. Regards, Dave.
