2001 Sienna Radio not working

I have an entertainment center for my 2001 Toyota sienna. It has center console for viewing and currently has VHS for playing tapes. The power for the player is underneath the back seat. I was trying to install a DVD in the back and was connecting the power cord to the DVD, and the radio went out and does not turn back on. I thought maybe it shorted out, so I checked the fuses in the front of the car and they seem to be okay. Does anyone know if there could be another fuse I'm not seeing or is there something else I should check or did I just fry my radio. Thanks
