Question about Computers & Internet
When the screen is black and the power light is steadly lit, shine a flash light at the screen. if you can see something, the inverter board is bad and the back light cannot turn on. if the power light flickers, reseat the power plug and put your ear to the back of the monitor where the power plug is. if you hear a buzzing or any high pitched noises; the power supply is bad. use the macufactures warranty for repairs.
