Mecool not booting

I plugged my mecool km9 pro and it on a light without blinking the blue light nor show at the TV screen if it would load. I’ve been battling with it and I try resetting it without not displaying anything on screen. Can’t even use remote to switch it off or on. Please what can I do cause it’s not up to a month I bought it. Please if anyone know solution to my problem I will appreciate any help thanks.
