Help No Video Sony Vaio S460p

I have a question I have a sony vaio s460p and the fan started making a lot of loud noises and I bought a new one to replace it. While I was taking apart the computer I followed all the precautions I was on a esd blanket and had an esd braclet I accidentily pulled off the ribbon cable that gets plugged in to the motherboard from the keyboard I don't know what it is called and I can't push it down all the way. The second mistake I did after I got the fan put on and put everything back togeather again the power ribbon cable I pushed it in but apperntly I pushed to hard and I bent the last pin on the right hand side by like 1/16 of an inch so I tried to cut the bent part off to trim it up and I'm able to put it in the power slot. The problem I'm having is after I get everything put togeather again when i press the power the power light comes on the cd drive will eject the harddrive spins up but I get no display no if I bought 2 more ribbon cables do you think it will fix the problem or is there anything else you could think of please let me know thank you

sorry if the post doesn't make sense my big question is can those 2 ribbon cables on that gets plugged in from the keyboard and the other one that goes to the power board if they are bent or broken could it affect the computers display from coming on it seems like the computer is getting power I just don't think its able to post but either way I get nothing on the screen at all not even a flicker so if i bought 2 new ribbon cables would it fix the problem thank you.
