Guys, need some help here.

So I was watching football in the wee hours this morning on Astro, everything worked fine as usual. But now, the remote/decoder is not responding? The TV displays a blank black sport channel and I cannot CH+ and CH- through either the remote or decoder.

All buttons on the remote and decoder will not result in anything. I'm using the Astro B.yond system. Appreciate the help guys.
