Last night I encountered the same situation with my new STB as 8 days ago when a firmware update bricked my DCT-700: my new STB has power but neither the XR2 remote NOR the power button on my TV would turn the TV on ! Both are plugged in to a surge protector. No issues with my other TV and box.
After numerous attempts to get the TV to turn on, I decided to unscrew the coax to the TV - wait about 60 seconds - reconnect the coax. After that, both the XR2 remote AND the button on TV worked fine.
STB: PR150BNM
Connection: coax to TV and STB -- no other equipment hooked up
Is this an issue with this box, or .... ?
I did find this old thread but it doesn't seem (to me) to apply:

Thanks in advance !
