My son dropped his iPod touch and the screen smashed. (4th Generation, 32 GB). I replaced the digitizer, LCD Screen it turned on but couldn't slide the unlock key. Reopened it and realized that a chip or ribbon on the upper left hand corner was split. Was wondering how do I go about fixing this ribbon or chip?
Is this a good question?

Welcome to the community.
You state in your description it is an iPod touch 4th Generation, 32GB, I think you selected the wrong pic.
You should try disconnecting then reconnecting both of the screen cables. Next, hold down the Home+Power button until it re-starts with the Apple logo and give it a shot.
If this doesn't work, check the connector on the logic board itself to see if any pins are broken. If a pin is broken your probably out of luck. With the right equipment, chips can be replaced, but not all iPod repair shops offer what you call "re-work" (i.e. PCB level repair).
After doing the above, re-connect the old screen and see if the touch screen works. If it does, then the new touch screen you bought is probably defective.

Btw, for all readers, I recommend ordering 2 screens and extra adhesive kits. This way, if you get a defective screen you have an immediate replacement and can ship it back without losing any more days without your device. If both screens work, you can always re-list one for sale back on Amazon, for example. When it comes to the extra adhesive, I do a lot of iPod repairs and still can mess up a kit from time to time.
Thanks for posting the pics. The yellow cable shown in the center photo, at the top left that looks like an "L", is your wifi antenna. It won't have anything to do with your touch screen. If the wifi antenna is split, then you can simply buy a new one ... it simply plugs into a connector on the bottom of the logic board.

Joleen, any way you could post a picture of the split "chip or ribbon" It will definitely make it easier to help you, if we see what you see. Click on the orange tab on the bottom left side of this screen "Images" and follow the instructions.
