Intel Display Troubles on Monster Abra Laptop

I've been using a Monster Abra laptop, but a few months ago, it stopped displaying anything on its own screen. I started using an external monitor, disabled the Intel UHD Graphics card to troubleshoot, but now there's no display at all. Even through the external monitor, there's no output, and I can't even access Safe Mode. No matter what keys I try, I can't access Safe Mode or BIOS settings. The screen had intermittent issues before, but when I tried using an external monitor, it stopped displaying altogether. I've had to get another laptop to manage my tasks, but I haven't found a solution for my Monster Abra laptop, and the problem persists! If anyone has experienced and solved a similar issue, please share your insights.
