Took my wally to deer camp and it was sleeping because it was off for 7 months. Log into account and told it to wake reciever,the tv screen went blank because no signal. Can't turn the wally off and it does nothing. Tried unplugging for 15 seconds and still nothing. Has green light on front but it's like the box is dead. Any suggestions? Can dish sent any type signal to fix it or will I have to sent box to dish.
