My monitor killed itself when I was sleeping. PLEASE HELP

I turned off my pc last night no problem. Woke up today and my monitor is not working properly, it flashes the Lenovo logo for a split second then turns black. It also flashes my desktop if I have it connected but also for a split second then turns black. Ive tried a different power cable, hdmi cable different outlets and I just wanna know if im doomed or if theres something else I could try :(
