Why is my phone just show a black screen

[Android Central Question]

My Omega Lite 2 phone didn't work already....
When I tried turning it on it just show a total black screen though it has a backlight.... Instead of showing the menu it's all black. I tried removing the battery,sim cards and SD card it still didn't work.
May I know what really happened and how to fix it?

Welcome to Android Central! Does the phone make any sound or vibration when you power it on? If so, then the screen has failed. If the phone doesn't make any sound or vibration, it might be a motherboard issue. In either case, contact the manufacturer if the phone is still under warranty; otherwise, bring it to a repair shop.
