Nokia Surge problem

Last week my Surge 6790 suddenly stopped working.  I had fully charged it less thsn 24 hours before, and had no problems with the phone all day.  I didn't spill any liquid on it, didn't drop it, etc.  It worked, and then suddenly - nothing.  So I charged the battery again, still resulted in no power at all.  I figured the battery (original that came with the phone, about 2 years old) was dead.  I ordered a new battery, replaced it tonight and am getting a very strange reaction from the phone.  The menu lights are not on, and there is no data appearing on the screen, but the screen is blinking.  I've had it charging for about 3 hours now and there's nothing happening except for the screen blinking.  When I try to turn it off or on, I can hear the small sound the Surge normally makes it first 'pops' on, but that's all it does.

Before this, I've had no problems with the phone and have been happy with it.  So, any ideas?  There's a new battery, so I guess this means my phone just crapped out on me?  Cut my losses and get a new phone?
