You have a bad main board most likely. You can try unpluging it for 5 minutes.

need make and model numbers to find out what it is

I own the same model. You have 1-2 Blown Capacitors. Take off the back cover, And look towards the center of the main power board. Look towards the center of this, and there are 2 capacitors side by side. You should see them swollen at the tops, even maybe a little black residue that has come out. I soldered on 2 new ones, and bingo! I would suggest replacing them both.
