Compaq Presario CQ45 screen remains blank... help

\015 The screen of my Compaq Presario CQ45 remains blank. Pressing the ON/OFF button doesn't help. The num lock and caps lock LEDs are blinking. But there seems to be no proper sequence (I checked the HP site for blink code errors). The LEDs sometimes blink, just once... sometimes they blink thrice and sometimes 4 times.. I am not able to place the error in any category. Please help me..!! :( I cannot send my laptop to the HP service center either. p.s. The fan and the CD drive seem to be working properly.\015

Answers :

I think the VRM( Voltage Regulation Module) IC Has blown UP. So it is advised to Take ot to the repair center.
Open the Notebook from the back side and locate the RAM. Now remove the RAM and place it again and check, you can even try inserting the RAM in different slot if any used slot is available.
