Q: no display on startup. reboot doesn't help.

been having increasing sleep problems. now it is impossible to tell if it is on or not, but it heats and i can perform a forced shut down by holding the button down for 10 seconds. i can hear the HD stop. when i boot up, there is no display and no backlight on the keyboard, hence i cannot enter password.

Mac OS X (10.7.4), 8 GB 1067 MHz DDR3

Hi there

This article may be relevant to you:

or search for "Distorted video" in the Apple support threads.

My MacPro had similar symptoms 11 months ago. I took it to the Apple shop and they replaced the graphics card for free. Unfortunately, it has happened to me again. That is why I am trawling through these communitites...
