For anyone who is thinking of buying the E 601 A3 Vizio, I have had my replacement set for a month now, and zero problems. No lip sync issue, and no other problem, I have an amazing picture with crisp sharp images in stunning colors and the blacks are as black as any plasma set I've ever seen. Black is a very deep black on my set, you don't get any deeper and I've looked at dozens of sets. The Vizio set has so many adjustment options in the menus for the picture to satisfy any videophile out there.
My set has been on 24 hours a day 7 days a week, and in my household with work schedules thats how it's been for years, and I'm inclined to believe that this Vizio will keep on ticking that way same as my old Hitachi projection set did .
I have been using the built in speakers on the TV, they are adequate in my living room and for my listening, however I do have the Vizio 40 inch sound bar with wireless sub woofer,, and I've had that hooked up and still no lip sync problems using the sound bar. I have the sound bar hooked up, and if I need a little more audio " punch " for a movie, all I do is switch it on and turn up the volume.
I am constantly amazed at the picture quality on this Vizio, when there is a close up of someones face you can actually see the pores in their skin, and every line or wrinkle on the faces, as well as any hairs they might have missed while shaving. I have never seen such detail on any set until I got this Vizio, I dont know what panel it uses but whatever it is , the TV gets an outstanding true to life picture. When I see it in an HD broadcast it's like the people are standing in my room in front of the tv its that sharp and crisp with amazing detail.
The colors are also amazing , I believe the processor is capable of 16 million colors, and believe me, you will definately see colors you have not seen on your current tv set.....
No blotchy light spots on this Vizio either, if the screen is dark, to black you don't see any light areas at all, it's solid black, no lines , no streaks, or anything . I would rate the picture quality at a 10 , each time I watch it I'm just blown away by the quality.
If you're on the fence about buying one, you really can't go wrong with this one . There have been failures in the earlier serial numbers, but I think Vizio has got it under control for the most part... When any of the sets that had defective panels went bad, Vizio replaced them with a brand new in the box set...... Several places have excellent prices on these sets now too as well as the popular 70 inch model.
