Yes, if you don't get any image through the HDMI or the VGA connectors, it's most likely you have a graphic chip problem.
Sorry
PS: It's possible to rework the chip, but I don't know if it's a patch or a long term solution. In the other hand, you can look for a replacement motherboard. It's a matter of price.

power off your laptop, Try to remove battery and then press power off button for 60 seconds, then give the power supply, it will start for sure
