Screen is frozen at kindle logo image and home button does not work

My kindle screen is frozen.

The screen turns white when pressing the home button for 40 sec but soon returns to same logo image.

PC does not recognize this device but charge it by using USB cable.

I bought it 15 months ago and never dropped it from high place nor in the water.

Customer service said this is trouble of hard and I should buy new one.

Can I fix it?
