Asus N71jq black screen, not booting

[matmat07]

I've tried connecting it to another monitor, but there's just no image being displayed on any screen. After I press the power button, the fan starts, the hard drive seems to be active, but it never boots into windows, as pressing the power again turns it off instantly, instead of going in a shutdown sequence. I've tried removing as much hardware from it as possible, but it still doesn't help.

At this point, I'd like to look for a service guide for it, try to check if my voltages are right. Any idea where I could find one?

Next step would be trying to send it for some time in the oven, as I guess the soldered video card must be defective, and there's not much else to do.

When you connect to another monitor did you press FN and F4 to connect to external sometimes instead of F4 it is a different key check your laptop manual.
Do you have battery led on ?
If not flash the bios
If yes most probably is the GPU but needs more tests.

It usually at least showed the post screen on every monitor.
Battery led works as expected.
Without seeing what's happening, how can I flash the bios?

Just letting people visiting here know, letting the motherboard cook at 385 F for 8min did the job, it managed to stay open overnight, I could even bring it to school today
