Toshiba Laptop L850 blackscreen

[edzhabs]

i tried removing the battery,power cord and press the power for 1-2mins still got nothing. using external monitor, the monitor was blinking. no logo and i think it's working fine `cause the lights of numlock and cpslock will turn on/off everytime i press it. also, i can hear the hdd spinning.
