HDMI Port Stopped Working

In the never-ending battle of having my Razer work as expected, last night while working in Unreal Engine, my external display (HDMI) suddenly stopped working. I tried 3 other cables that I had around (they all work when connecting other devices to the same display), so I can confidently say the Razer Blade is the weak link in the chain. I have been struggling to find any good forum posts or anything to troubleshoot this. Is it just time to bring it into the repair shop? In a strange turn of events, my laptop screen has been flickering every 2 minutes since I received it. Since this event happened, I haven't had my screen flicker, but losing the ability to have an external display is too big of a limitation and I may finally just buy a workstation.
