Is my phone bricked?

Certainly seems it is...

The HTC Inspire 4G from AT&T. I use it with Straight Talk. Bought secondhand on eBay, has worked fine about 6 months. Worked fine when I went to bed last night. Got up this morning, and nothing. Amber LED lights when charging, but the phone won't turn on. I get 7 vibrates when I attempt to power on...then I have to pull the battery, replace it, and try to power on again - 7 vibrates and nothing on the screen.

Tried holding volume up and power and volume down and power hoping to enter recovery mode.

Am I stuck with a bricked phone? Or is there some other hope?

Guess I better hop on eBay and see if I can find another sub-$150 android phone.
