Check the capacitors in the power supply board to see if any of them is damaged.

Change the damaged (as well as the others connected in parallel with it) with other(s) of the same capacity and voltage. If you can't find the exact replacement part, other capacitor of the same capacity but larger voltage will do the trick.
