I've a Vizio VA26L that can't decode digital stations on cable... I just get a blue screen, but my channel scan adds the channel because there is a signal. My other Vizio E371VL has no problems decoding the stations. I've done some searching and could not find a firmware update. Does anything know if there is a bootleg firmware update or could suggest a replacement tuner box that would pick up all the analog and ALL the digital stations?
