Overview / Main Features
The Vizio E320VP is a LED edge-lit 32-inch LCD television unit designed and sold into the North American market. The LCD television features rather basic specifications of 720p resolution at 60Hz and a 100,000:1 contrast ratio. The E320VP features a LCD panel manufactured by LG Display. Unlike typical television sets, the Vizio E320VP comes with an external power supply and is assembled completely in China. This suggests that the E320VP design is more reminiscent of a computer monitor rather than a true consumer television. Internally, the Vizio is powered by a Mediatek MT5376 video processor IC and features a Samsung ATSC tuner module.
Pricing and Availability
Pricing - The Vizio E320VP currently sells on various online retailers for as low as $350.
Availability - North America
For the purposes of this teardown analysis, we have applied a lifetime production volume of approximately 750K units.
As a reminder, teardown volume production assumptions are primarily used for our cost analysis in terms of amortized NRE and tooling costs, especially for custom components specific to the model being analyzed (mechanical components especially). Unless assumed volumes are different by an order of magnitude, minor changes in volume (say 1 million vs. 2) rarely have a large net effect on our final analysis because of this.

What Is Not Included in our Cost Analysis
The total materials and manufacturing costs reported in this analysis reflect ONLY the direct materials cost (from component vendors and assorted EMS providers), AND manufacturing with basic test. Not included in this analysis are costs above and beyond the material manufacture of the core device itself - cost of intellectual property, royalties and licensing fees (those not already included into the per component price), software, software loading and test, shipping, logistics marketing and other channel costs including not only EMS provider and the OEM's margin, but that of other resellers. Our cost analysis is meant to focus on those costs incurred in the manufacture of the core device and exceptionally in some circumstances the packaging and literature as well.
Country of Origin / Volume Assumptions
Based on device markings, we've based our analysis with the final assembly in China. Furthermore, we have assumed that custom mechanicals (plastics, metals, etc.) were also sourced in China.
Country of origin assumptions relate directly to the associated cost of manufacturing, where calculated by iSuppli. In the cases of 'finished' sub-assemblies (such as charger unit), we do not calculate internal manufacturing costs, but rather assess the market price of the finished product in which case country of origin assumptions may or may not have a direct effect on pricing.
Remember also that labor rates are applied directly only to hand inserted components and systems in our bill of materials, and although regional assumptions do, these new rates do not have a direct effect on our modeled calculations of placement costs for automated SMD assembly lines. "Auto inserted components (such as SMT components) placement costs are calculated by an iSuppli algorithm which allocates a cost per component based on the size and pincount of the device. This calculation is affected by country or region of origin as well.
Design for Manufacturing / Device Complexity
The Vizio E320VP LCD television has an overall component count of 1078 (excluding box contents), of which 888 components reside on the Main PCB. In comparison, the LG 32LE5400 television unit has an overall complexity of 2538.
Component counts have a direct bearing on the overall manufacturing cycle times and costs, and also can increase or decrease overall yields and re-work. Our calculations of manufacturing costs factor counts and more qualitative complexities in the design. The cost of manufacturing is also, to some extent, decreased in this case because of assumed labor rate applied for China.
Note that manual labor has a much smaller effect on auto-insertion assembly lines (for the Main PCB, for example), where manufacturing costs are much more capital equipment intensive and driven by these investment costs.
