All in one won't power up, light & fan come on for a second but nothing on screen

Pavilion all on one

Not aware of any recent changes or updates, i thought we had lost it a month ago but after weeks of trying it decided to work for a while. Nothing now when you press the power button unless you take the cable out and put it back in again, then light & power comes on for a second then goes off
