Latitude 12 (7275)

I have a latitude 12 (7275) that fails to boot. If I press the on button, it vibrates and the led goes on, but nothing on the screen.

If I try turning on with vol down pressed, the screen goes on solid colour, white, then red, then green,then blue . This happens around 3/4 times, then it powers off.

Any ideas anyone?

Thanks in advance
