It seems the connector is partially removed,
If you are able try to remove the monitor bezel, and look the connector. Usually is a easy to unplug it.
I have replace a complete monitor from another model of DELL, and is not necessary ro open all laptop to check this)
Look on that:
Unfortunately, I fear the worst that your recovery disk is corrupted/broken. If ever see like this before. If you so sure the disk is still in good condition, try to make a copies in your friend's computer. If it's succeed to create a backup of your disk, then I was probably wrong. You can continue to recover using the backup disk. If it's failed, then the worst case, you have to buy another recovery disk from Toshiba itself.

when you have the memory in and you boot up does it look like the hard drive LED is flashing? If so then its booting up into windows and that would mean a bad Display. If nothing happens then try a different stick of good RAM and see if it boots up then, if still nothing then it sounds like a bad motherboard.
