What s the harm of being a plasma TV for a sample?

Personally, I don't recommend you to be greedy for this cheap. The details are as follows:

Panasonic plasma claims to have a screen life of 100,000 hours(Changhong's don't know),If you watch TV for 6 hours a day,On the premise that other parts are not problematic,Then theoretically, your TV can be watched for about 40 years。 On average, your TV will cost you a few cents a day. What I mean by this is that TVs are consumer durables, and we don't want to use one.

In three or five years, you have to change the machine. So, don't take this risk for the sake of these thousands, hundreds of thousands and hundreds of dollars for so long, you can calculate that you can save one less cigarette or two less ** every day, no matter how bad it is, don't miss this money.

The advanced engineering menu looks at how many hours the machine has been used, and if it is more than 50 hours on the machine, it is not worth considering.

Because generally speaking, in the prototype of the store, in order to highlight the effect and attract the attention of customers, the color and contrast will be adjusted very high (which is very bad for plasma TV), so that customers feel that the picture is very bright at first glance.

And the counter heat dissipation of the shopping mall is generally not too good, the circuit board inside the plasma is very complex, and it works continuously for a long time in a state of high heat, and the probability of circuit board problems is very large, and the machine will not work continuously for less than 10 hours a day from the opening of the store to the close.

In other words, prototypes are generally run for a long time under overload, and 50 hours of boot time in the store is equivalent to watching several 50 hours at home. Such a big TV,Maintenance is not a joke,Panasonic plasma,The cost of changing a screen is about the same as buying a new machine。 The landlord thinks twice.

Good luck with your purchase

If there is more dust, the appearance may be touched, but it does not affect the use, and some people may feel awkward. I think it's very good, since there is definitely no problem with the quality of the prototype, some special smells have also dispersed a lot, the price can be cheap, and there is no difference in after-sales maintenance.

The imaging principle of plasma TV and liquid crystal is completely different, liquid crystal illuminates the picture through a large backlight, while plasma is each pixel emitting light.

The plasma screen is filled with plasma stun guns, and each pixel is a gun that can be lit up.

In fact, each pixel in a plasma screen is made up of 3 glass air chambers.

And so on through a large number of glass chamber chambers to form a flat plate.

1、The reason why plasma TV is really eliminated is actually involved in a huge business conspiracy。

2. The plasma technology was first developed by major electrical appliance manufacturers in Japan, because plasma technology is much more advanced than ordinary liquid crystal technology. Not only is the response faster, the color is more permeable and real, but it also has the biggest shortcoming of LCD, pure black.

3. At that time, Samsung was actually far behind the five major Japanese electrical appliance manufacturers in terms of technology, but Samsung directly took the method of buying plasma panels from the five major manufacturers for sales, so that the five major Japanese factories were optimistic about the prospects of plasma.
