I Replaced screen(workd perfect) I opened again and screen went white

Hi, i replaced my ipods broken screen and it worked perfect but then i found that wifi isnt working so when i replaced the wifi antenna i broke the wire(ribbonn) on left side almost half way down and when i put it all together the screen was white (the same screen workd perfectly before) i think it maybe the ribbon i broke? i could really use some help

I tried the home, volume, and power button thing didnt work
