First off, after reading so many reviews for the Sharp 70" which I was so close to buying, I decided to go $1-200 cheaper than the cheapest Sharp model in the 70" lineup and buy the Vizio. I"ve always wanted to try Vizio because I"ve heard a lot of good things about them so I did after finding that this was only about 1 of 3 or 4 of the total 70" LCDs on the market from which to choose. My choices were very limited. I read much good and much bad about the Sharp image. So, after reading about the Vizio and finding less negatives for their model than for the Sharp, I went with Vizio.

Sharp apparently has issues with the big ones that actually require professionals to come to the house to calibrate the image because buyers just can"t make it look good no matter what they do. Many of those complaining about this were seemingly "qualified" to make the adjustments, having such extensive experience with LCDs. Also, I don"t know what Sharp is doing with their model numbers but I swear, I had to (with a fine-tooth comb mind you) painstakingly go through the exact specifications of each of the models, and I think there were like 8 70" Sharp models to go through at rather dramatically different price points. Reading reviews for each, each had their own unique image issues even though they all had the same comments regarding not being able to adjust the picture to look good at all. By the time I was done with hours and hours of research over about 2 weeks, I basically gave up. That"s why I was so happy to find the 70" Vizio.

My only complaint is about the white. This complaint would in NO WAY influence my decision to buy this Vizio, but it does exist and I think it"s more of a size issue because I noticed the same thing on the Sharps when comparing them side by side in Best Buy. The 60" Sharp had the best pure white and was very bright. The 70" Sharp that I contemplated buying showed white as a very light blue that"s just a hue, like the bluish you might see while looking at white glaciers. It was noticeably dimmer than the 60" Sharp. The 80" Sharp cinemawide was the dimmest with the greatest bluish hue whites. I would not buy that one. The picture just isn"t good enough.

I have the 70" Vizio side by side with the 37" Samsung running the same shows and the Samsung white is white (snow for instance was pure white on Samsung, bluish hue on Vizio). Given the Samsung"s smaller size though, and, if the blueish hue is the result of the large size of the TV and edge-lit technology, that would make sense. I even turned the contrast, backlighting, and brightness to 100% on the Vizio and it was still bluish. However, oddly enough, while playing my PS3, I noticed that the whites were pure! Explain that! There goes anything that might cause the bluish hue to come from size (but it still seems apparent to me that size causes dimness, perhaps more so with the newer edge-lit technology). I don"t know. I"m not an expert but after seeing all of the different things that can impact picture quality, I"m almost left with the thought, why bother? You"ve got the following things weighing in to what you"re trying to compare: Screen size, picture settings, each TVs built-in technology (60 vs. 120Hz, 720i vs. 720p vs. 1080i vs. 1080p), whether the channel is in HD, what the program you"re watching is shot in (non-HD, 720, 1080), streaming vs. non-streaming content (Netflix, Hulu, On Demand, etc.), bandwidth speed and the quality of your wired/wireless connection, whether on a gaming system or watching any of the above forms of programming, and the list goes on and on.

After seeing and researching all of this, and since it"s impossible to compare apples with apples if you have the chance to do so when comparing TVs of different sizes, brands, technologies etc., I"ve come to the conclusion that you should just buy what you like after seeing it in person. I never saw the Vizio before I bought it but it"s the best advice I can give in my opinion (I took a chance that paid off so far). Even when I change channels from HD to standard, some look horrible (even on the Samsung), and some look fantastic. How do you know what"s supposed to look good when you have no idea what each channel change is going to do to your image? I would say on average, every other channel I change looks better on the other TV. Samsung excels in whites, and the Vizio seems to be more colorful and sharp in many programs.

Hey all. Brand new to the forum. I just acquired one of these TV it has been troubleshooting it no picture condition. I"m really surprised that I went to Target yesterday and found the same exact TV still on sale along with a 60 inch counterpart. I found sharp panels used in very very many large screen TVs. Anyway one of the three pin transistors most notably the one labeled COXA has apparently a short between the center pin to the top right. This transistor operates what appears to be is a 3.3 volt voltage is for the gamma IC processor. I have two of these boards both with the same problem the new one that I ordered I haven"t even connected to the panel yet and it was failed from the box. It appears that these boards for previous buyouts from previous failures it has a Chinese label on the back of the board but it came from ebay in the US. I myself am trying to still figure out what"s going on I contacted the vendor and they"re setting yet another board. I can"t seem to locate even in my parts stash thid 3 pin MOSFET with this label. Cox is the equation for the silicon inside the MOSFET it has something to do with the wavelength. This is a really odd transistor. I think its funny how shopJimmy sells this transistor and the EEPROM 8-pin IC. Has anyone successfully repaired this board yet are replacing the components?
