AW2725DF, stuck in burn in test mode, can't access OSD

I was using my PC and everything was running smoothly. Shut down and went away for like an an hour 30 mins. 

Came back and turned on the PC. I have 2 monitors, Alienware OLED being the primary, turned on the monitor and I saw colors flashing one by one. whereas the second monitor was working fine and displayed windows. Alienware monitor is stuck in flashing colors loop. It seems to be in burn in test mode and I cant seem to access the OSD panel either. There were some solutions for some other models and none seem to be working for mine. Please help if anyone has a possible fix as dell support wont be available till Monday 9AM IST
