I absolutely love this TV. It has a fantastic picture, lots of great apps, the remote is great, everything about it is fantastic - except for one thing: the TV is unwatchable.

This TV has a major firmware flaw. When the TV encounters a significant scene change, particularly if the scene change involves a sudden, black image, the TV turns itself off. Pulling the power cord for a few seconds to reset the TV fixes it for a while - but the problem eventually returns. Watching a Blu-Ray disc is impossible - the TV turns itself off almost every 30 seconds or so. It happens when watching something via HDMI, it even happens (less frequently) when watching something on the internal built-in Netflix app. Obviously there is a firmware problem in the code that is decoding and displaying the image - I suspect when an exception happens in this code, the TV turns itself off.

Doing a Google search for "M550SV" and "turns off" you can see that this is not an uncommon problem - it's quite widespread. It is also happening to the M420SV, the 42 inch version of this TV. Repeated calls to Vizio customer support result in denial of any known problem, and claims that it must be "power related" - telling me to go buy a surge suppressor (I already have one on the TV). When I pressed them on the issue, they agreed to send a repairman to my house to "replace the power supply."

Replacing the power supply is not going to fix a firmware problem. The problem can be easily demonstrated by playing a pre-recorded video that makes the TV turn off at the same spot every time, as I demonstrate in this video.

Unfortunately, as much as I love this TV, I am going to have to return it. I cannot live with such a major fault. And while I have purchased (and recommended to others) Vizio TV's (as well as other products) before, the replacement for this TV is not going to be a Vizio. What a shame.

Verified Purchase
I received this TV on Friday 6/17 after a lot of nail-biting because of the power/firware issue mentioned by a few other people. First off, the TV is very slim and the picture on it is very good. I am still futzing with the picture options but I think I have everything set the way I like. I have it connected via HDMI to a Comcast DVR and also an XBOX 360 (also via HDMI) and everything is good there. Also, I was able to get the unit very snug to the wall using a PYLE PSW598UT wall mount (also from Amazon). I have a recessed power outlet behind the TV and all of the cables are hidden and it looks really nice being such a thin TV and then having it right up against the wall. The TV was on a lot today and never shut itself off. I also got the TV to recognize my wireless router and I played with the apps a little bit. The remote is a bit clunky but I like the way it works. The only issue I have with it is the sound, which is okay but not great. I changed the audio settings and equalizer settings (I set it to ROCK which seems to have the most bass). But as I went between the unit that this one replaced (a 50" Samsung which is now in a different room) I noticed that the audio on the Samsung is MUCH better than the Vizio. The 37" Vizio I own had sound that was so bad that I had to by a soundbar for it. I don't think I'll need one for this 55", but it's always possible I'll get one. I will update this review as pros and cons come up but at this point, I'm liking it.

** UPDATE **

I have been playing with the video settings on the TV for the past four days & watching quite a bit of baseball, news and other HD content.

Overall I enjoy the Vizio M550SV TV. I bought it at Costco at the end of the model year for $1199. They just now have a coupon deal for $200 off and I went back and got the additional savings. Even though the new models are just about to come out, for just under a grand this TV is a smokin' deal. I added the extended Square Trade warranty for $59.99 and so I have 5 years of total coverage, to boot.
Add what I wrote to other owner's comments - basically, it's just a good TV that does what you want it to do. It's not the very best, just the very best for the money. It's also an attractive set without some of the flashy distracting bright silver styling accents that Vizio has used in the past.

The reason I'm adding my review to the mix is just to let potential buyers know a couple of things that I've discovered.

1.) Updates to firmware

This is an internet TV. Updates to firmware come through periodically over the internet. This process is automatic. You are notified at power-on when this occurs. You must have the TV connected to the internet to get these updates. You need a wireless or a wired connection. I use a wired connection and have not used the wireless option. Updates to firmware include new VIA apps, functional improvements to the TV itself, as well as updates to the apps.

2.) PIP
This is one of the prime reasons I had to buy this TV. It's a hard feature to find nowadays. I think the advent of time-shifting via Tivo devices and their ilk has rendered it less useful for most people, but since I use the QAM tuner in the TV to watch basic cable from Comcast in Boulder, Co., I find value in using PIP to "power watch" more than one channel at once.
Yes, this set has PIP, and POP is also pretty useful.
