Is everyone going by the Seriel Number entry on Samsungs site for production date?
If so you may be going the wrong route in actually knowing what dates are on your parts.
As parts are stocked and pulled during sub assembly.
Some bins are well stocked and others depend on supplier batch shipment.
I assume the Lens assembly is one part of many that may be limited order and reordered in limited quanity as needed.
I stated that I have parts from 04/08 though I do not know if all parts fall into the same date range.
Since I purchased mine early 4th quarter, it is possible that in that time frame newer assembled parts were being trickled into part of production. As I do not think any of these TV's would have been in production after January 09.
I know for a fact if Samsung uses a limited production item to produce a product, they will outsource. So to plainly state, at any time durring 12/08 some or many LED DLP TVs may have a Lens that was not of the same batch that was originally ordered.
Oh, by the way 2008 LED DLP TV's are the minority of all TVs for 2008. So don't expect every little part in every 2008 LED DLP to be from the same provider or batch.
Yes, my 2010 Panasonic 42C2 performs better than an S2 No floating blacks and keeps the lowest black levels.
