Before you buy any of these off brands, maybe you'd better read
this.
A good part of this article is designed as sensational journalism. Specifically the Vizio part. First of all Vizio does in home repair on all TVs 32 and up during the warranty period. The second part -sending the TV back to the manufacturer AFTER the warranty is expired is stupid to even bring up. AFTER the warranty is expired you would have it repaired by a local shop just like any brand including the Sony, Panasonic etc.
The part about extended warranties is a bit overdone too. Indeed with price of extended warranties plus the cost of the Tv may often equal the price of the more well known brand without the extended warranty.
Interestingly all of the advertisers on his site are considered tier 1.
Brands like Olevia (who has been around a long time in the business computer field with it's Syntax/ Brillian monitors) and Vizio are reasonably priced in comparison to the "tier 1" brands and often produce as good a picture. Not as good as some but good enough for 90 percent of the population.
Vizio did become a top 3 seller this year with viral support, to the point of beating Samsung one quarter as the top flat panel seller. If the product was bad it would not have had such outstanding sales.
There are many accounts of poor service from the Tier 1 brands too.
Now are there lesser brands to worry about? Definitely Akai, Westinghouse, Zenith, Insignia and Funai to name a few.
