Its either your back lighting, power supply, main PC board, or sticky keys on the input board..... or something else.

If you provide the model number and any observations such as, makes a flash of light, or not, how long before shut down as in 3 to 5 seconds or after a minute or more, whether the standby light is behaving normal or not, it would really help in pinpointing the issue so you can fix it.
