Black screen at power up Compaq

I've has thisl issue with a Compaq Presario cq56-115dx black screen at power on,everything else seems to power up, caps light blinks showing what it could be that's not working as noted above on hp's support link however this model of laptop/notebook will not make a beeping sound, never did when the monitor would power up correctly. I installed ssd new mobo still black screen replaced ram,checked connection ac/dc you name it still black screen no Compaq logo nada. I contacted hp no reply. HP no warranty and no assistance policy. I'm think its lg LCD/monitor not sure if customer overheated unit, no spills where found inside reply please thanks ahead guys, Rpd p.s. reosted in thread thanks greg

Do you get any windows sound?, Usually IF its the inverter the laptop will boot as normal playing all the sounds ect (not all models), if you do get sound then the best solution to attach and external monitor to be sure its nothing more serious
Though we are stabbing at the inverter, you can usually see at the correct angle a faint picture behind.... or the worse case it could be the screen has failed thus you just wont get any sort of picture at all...

no this model didnt make sounds during start-up just flashing of the caps lock button. it was the monitor itself thatwent it was only 7 months old and an LG monitor. wow hp is really making crap set the customer back $100.00 with installation.
