Facing TV Problems? Ask a TV Technician.
Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, bear with us; re-confirm and post back with the complete model number of the Vizio TV.
Is the TV completely / electrically dead? ...or is there some indication of power such as a standby LED light?
Sorry but "...s401cd..." is reported back as an invalid Vizio product / model number. Please re-check the model number. Thanks
Still, have you tried unplugging for an extended period of time? ...and plugging back in into another outlet?
