My MacBook computer screen will turn on fine and then it might go black, but then when I push screen back more or forward more it will turn back on. Any help would be nice. Thank you.

This sounds like one of the inverter cables is damaged. These sometimes get pinched in the hinge. That a lokk at step #8 of this guide: MacBook Core 2 Duo LCD & Inverter A1181 (fast method) Replacement

+ Inverter cable most likely. To test the inverter cable. Preform a continuity test using an analog multimeter/multitester (One with the needle.) while moving the wires around. Do this for each wire in the cable. If the needle sweeps hard at any point is an the wire and the cable needs replaced. Digital multimeters usually have to slow of a reaction time for this type of test and/or have circuitry in them to ignore quick fluctuations in a reading.
AB - Good info on the analog multimeter ;-)
My daughters MacBook Core 2 Duo (early 2009) had a similar issue. Tilting the display far back usually resulted in the display going blank. Tilting it forward usually helped.
I just replaced the display data cable, and now it is working beautifully again.
Replacing the display data cable involves disconnecting the inverter cables and free them from the hinge cover. I can't be sure, if my data cable replacement actually just refitted the inverter cables so they don't get pinched anymore!
