HELP ! My Samsung Smart Tv will not turn on but red light blinks 5 times while turning on.?

My tv is a medium sized tv but my tv worked for 3 to 4 years, ever since my niece dropped it on the floor it worked for a month and now the screen does not show anything, but the screen is not cracked or anything it just doesn't show any picture. When I turn it off the red light comes on and stays on that's when I know its off, but if I turn it on the red light blinks only 5 times but no picture shown, I tried to reset the Samsung smart tv but nothing happens. Not sure how to reset it by the way? My tv does not take buttons it has a joystick that controls but it also presses, is there any solution to resolve this issue, I also tried the volume while it was on and it makes sound but no picture, I even tried to look up some information.
