Yeah, if there is no menu, it's either a lockup, in which case you need to reboot, or you accidently switched the input on your TV set (e.g. by pressing the INPUT button on VOOM's remote). Most likely a lockup, since the icon is red.
Try unplugging the STB for 20-30 seconds. After you plug it back in watch what happens on the STB's front panel. See if the horizontal lines on the right side will start blinking in sequence. Which one will be the last to blink?
