To anyone that can help me I would like to thank them in advance!

Yesterday, I dropped my 7250 on the concrete. The battery and the battery cover both went flying. I brought everything inside and re -installed the battery and now I have a blank screen. It appears to me that the phone does not even power on..When I try to power it on nothing occurs! I plugged my phone into my wall charger and the red light stays on for about five seconds and off for a few and then back on for five seconds etc etc.

Again, thanks in advance
