jubril olabode, Reset procedure to try:
1. Hold (menu) and (vol-) button on the side of the TV
2. while holding these, press the power button on the side of TV (NOT remote)
3. Blue light comes ON and stays ON
4. Wait 10 seconds then let go of (menu) and (vol-)
5. wait another 30 seconds and some type of picture should appear, If that does not work, unplug TV for 10 minutes and then hold power button on TV for 60 seconds, plug in and turn on
If this does not do it, take the back of the TV and check for possible bad power supply/capacitors on the boards or you may have to replace board. See video links below for more detailed info. Good luck.
I hope this helped you out, if so let me know by pressing the helpful button.
