In what context please, replacing the screen may have led to the notebook being turned this way and that - as in left and right/upside and down however I cannot imagine that you have not taken anything but total care with the screen replacement task
I think I made things worse.
The fact that you are hearing a ticking sound may suggest a problem with the HDD, this ordinarily will result in a failed POST (power on self test) and with a branded notebook such as your Dell or an alternative example an ASUS product you will get a BIOS and/or logo splash screen + an on screen message such as "Hard-disk drive failure , strike the F1 key to continue, F2 to run the setup utility etc, please listen to the example sounds at the attached link and let us know if there is any comparison to what you hear, Failing HDD sounds apologies, back to where I was going with this, if you are not getting the aforementioned on the replacement screen or an external display something more untoward is suggested as to what is going on.
From your OP;
Can you explain what sort of damage, was the computer still functional but with a damaged display such as the one here (picked up by the upper right hand corner of the screen) or was the notebook behaving in the same way that it is now.
