Re: Vizio m550sv shutting off after boot up
I got the input changed from rgb to hdmi and now it will stay on longer sometimes for 30 sec sometimes up to 5 minutes sometimes audio will come on after 45 seconds then video a bit later sometimes not. All functions are delayed like the processor is overworked or ram is filled up menu functions are delayed by 3 to 20 seconds per button push.Leave a comment:

Vizio m550sv shutting off after boot up
Plug the set in and you get the amber logo then turn on with remote or button on side logo turns white screen comes on with vizio logo then shows the selected input for a couple seconds and shuts off. For a couple tries when i first plug it in it may stay on for a couple minutes and then you'll get picture then after another minute or 2 sound and eventually off. During the on time any functions were delayed by 5 to 10 seconds. You could hit menu then 5 to 10 seconds later it would come up down arrow then to 10 seconds the menu would move down one slot hit ok then 10 seconds later next sub menu... -
