Machine won't power on
MacBook Pro 17" Model A1261
First, I'd like to thank all the contributors to this site. You take the fear and stress out of dealing with many issues.
I'm pretty sure something overheated and burned out on my MBP but I'm hoping to gain assistance for myself and others on diagnosing the issue.
I have already performed the recommended troubleshooting steps from apple support as well as opening up the case and cleaning all the dust from my machine since this issue began I saw no immediately apparent signs of damage while inside the case. I have also scoured this forum for more info but could not find an issue matching mine exactly.
I was running a Parallels Windows XP virtual machine on os 10.5.6, closed the lid and left the machine unattended. Upon my return the machine seemed to be still running but was hotter than I've ever felt and the screen would not illuminate. I shut down using the power button and attempted a reboot which was unsuccessful. When I tried to start the machine I was presented with a brief flash of the LED. If I hold the power button down the LED will stay on for a couple of seconds then fade and flicker rapidly about 20 times. The problem has persisted with each subsequent attempt to start the machine.
I have posted a video of the attempts on YouTube.
Does anyone have a diagnosis?

UPDATE
Thanks for the quick response. There is a dvd in the optical drive currently and I haven't a clue how to eject (mind you I didn't inspect when I had the case open - silly me).
I will try that, but I really get no response from the mac. I am running OS 10.5.6, with Parallels I was running a virtual machine concurrently with the native OS (Mac).

Question: Is there a way to eject the DVD without power? It's my wedding photos and video
Respectfully,

Ist dies eine gute Frage?

hi Christoph,
Were you able to solve the problem of your macbook?

Still having no luck here. Any suggestions?
I've tried to zap the PRAM.
I've tried resetting the SMC (both ways).
I've done all the power tests.
I've tried a different battery.
I've opened and cleaned the case.
I've tried to start from system install disk.
I've tried to start in target mode.
All I get is the result demonstrated in my video.
Anybody understand what my Mac is trying to tell me?
