Well you’ve got a few problems! First I don’t see the MagSafe chargers LED even being lit so the charger and/or the MagSafe port on your system needs repairs or replacing. We can see the battery image on the screen is telling us the battery is not getting charged and is dead. Given the age of the system I would suspect the battery is just worn out and needs replacing. As for the lines at the bottom of the internal display the fact the system has not booted up fully should first be checked out and ideally checking if the display its self needs replacing by plugging in an external display to see if the image is OK on it.
