And with this information, they project a set amount of TV's to make and ultimately, to sell to their sales channels (retailers, resellers, etc). They project what they think will sell given their research on consumer demand, the general condition of the market, whether the economy is growing or shrinking, and all that good stuff. Now, as you may know, TV manufacturers make their TV's in batches. So they may be the same TV model 'externally' as in the TV label sticker will insist that it's the same TV model but inside the TV, the parts may be completely different as well as the TV panel itself. Manufacturers make a series of TV panels and circuit boards that are designed only to work within certain batches of complete TV's. Today, we're going to talk about what the serial number-specific circuit board means to you and why you should be aware of it. We think that in time, it would become commonplace for other manufacturers to start adopting this methodology to combat independent TV repair shops from effectively performing repairs for customers at a fraction of the cost that the major TV brands would ordinarily charge at their authorized service centers but this matter deserves an entry all on its own for another time. Nowadays with the advent and dominance of LED TV's in the common household, other lesser known brands like Vizio are slowly adopting this method as well. The first conception and use of this method by TV manufacturers is largely unknown but perhaps one of the first iterations of this started with Emerson (who also make TV's under other brands like Magnavox, Philips and Sylvania) and then later on, Sony and Toshiba adopted it as well. Ah, the serial number-specific circuit boards.
