Make sure you get the best TV at the best price
TV has a million-to-one contrast ratio
Every TV manufacturer lies about contrast ratio. Not a single one is remotely accurate. So it's impossible to prescribe an exact number to any TV given only the manufacturers data. The fact is, plasmas have better native contrast ratios than LCDs (LED or otherwise). There are three local-dimming LED LCDs on the market this year (Elite by Sharp, Sony HX950, and LG LM9600), and they're all extremely expensive. These offer similar contrast ratios than the best plasmas, though not exactly.
TV has better sound
TV A has better sound than TV B. The fact is, no TV sounds good. So all they're really saying is, This TV sounds less bad than this other TV.The thinness that we all love in flat-panel TVs means the speaker drivers by their very nature have to be very small. Small drivers can't do much to create sound waves.
The wiser salespeople will direct you towards a sound bar or other home audio system. This is definitely where you should spend a few dollars. Pretty much every sound bar will sound better than the TV speakers, and the better sound bars actually sound pretty good.
TVs break all the time and You need an extended warranty
TVs come in for repair all the time." From a rhetorical standpoint, this is a rather brilliant argument. This person works at the store. They see lots of TVs coming in for repair.
LED TVs have the best picture quality
Every LED TV is just a standard LCD TV that uses LEDs to create light instead of the "old-fashioned" cold-cathode fluorescent lamps (CCFL). LCDs have their positives, like light output and lower energy consumption, but when it comes to a direct picture quality comparison, plasmas have better black levels, better contrast ratios, and better viewing angles (for those not sitting directly in front of the TV).

This is the one that eliminates any guilt I have impugning the good name of some hard-working salespeople. There is no picture or sound quality difference between any HDMI cable. None. At all. So if you spend $3 or $300, the image and sound will be 100 percent exactly the same.
