Hi Peggy. Welcome to justanswer.
Insert the batteries, remove the sd card and hold down the POWER button for 10 seconds and then check if it powers on or not
How old is your camera? Most probably the power circuitry has gone down. The battery is not able to supply proper current and voltage to the camera to function. Either a transistor or capacitor in the power circuitry has gone bad.
Yes it can be repaired. You will need to take it to a local repair store. The technician will test the components and it won`t cost you much.
