Blank Screen - Razer Blade 15 2019 Base Model

Hello, After putting my Razer Blade 15 2019 Base Model into sleep mode this morning, when I try to wake it up I no longer have anything come up on the screen. The logo on the back is also not lighting up. I have attempted to connect it using an HDMI cable to an external screen, but there is no signal. The keyboard chroma is lighting up, but the razer mouse I have connected to the laptop will not light up either. The indicator light on the front of the unit is a flashing green, which to me is indicating that the system is awake. Does anyone have any idea of what the problem might be, or steps I might be able to take to resolve this issue? I only got this unit at Christmas, so it's only 7 months old. Any help is appreciated. Cheers
