@ssv8, Fannie, In case you would like to attempt the repair, below are links that show what is involved in replacing the screen assy. in the A7 and a link to replacement screen possibly which you can do a search using your make, model# for better pricing perhaps. If not wanting to do repair best to pop into a couple good local shops for an estimate and turn around time as price/time can very quite a bit from city to city/state to state/ etc..
