I cleaned it now it won't work, it's not showing

what did you clean it in??? the dish washer???? some times if the plug is removed on an older unit or the power turns off, they just wont start up again,,, its a fult with the micro chips in the computer, the suden surge of power when switshed back on just blows it up,,, iv lost at least 3 in this way
you could try pulling the plug out again but its not very likely to get it working again the real problem is they just dont build in a soft start on them now, so if unpluged then switched back on the computer get a wopping big smack of power that just blows is socks off,, like i sead, i lost 3 evey time the power was cut off they died on me
