case analysis:

A few days ago, the Industrial and Commercial Bureau of Langxi County, Anhui Province seized a sale of shoddy refurbished machines. Law enforcement officers found that the refurbished machines for sale were marked with manufacturers, trademarks, and 3C certifications, but there were several cracks in the shell, so-called registration. The trademark has not been found in the State Administration for Industry and Commerce, and the 3C certification is also purely fictitious. County villagers get the cost of returning and knowing that the TV they purchased was actually a refurbished machine, and they couldn't help but be horrified. The newly purchased machine turned out to be a "time bomb."



1, see the packaging of goods.

The outer packaging of the new product is intact, and the plastic bag inside the package is also intact. The unopened packaging film should be free of dust and relatively clean. The old product packaging would not be so perfect.

2, look at the TV shell.

The shell of the new product is a bit shiny, and it shines when exposed to sunlight. The body is dust-free. Old TV body dust may be wiped clean, but the screw hole and the heat of the dust can not wipe off.

3, watching TV screen.

The screen of the new machine is bright as a mirror, and no scratches can be found on the top, and there should be no dust. The old machine may have scratches and impressions left by the fingers.

4, watching TV power cord plug.

The metal plate of the new machine's power cord plug has no sign of insertion and removal. For televisions that have been used many times, the metal plugs of their power plugs generally leave traces of contact when they are plugged and unplugged.

5, see the image.

The new TV's image is quite clear, the colors are very vivid, adjusting the brightness, the contrast is very obvious, black and white images are very obvious, that is when playing black and white images, black is white or white, should not Do not add any colors that you should not have. The lack of brightness of the old machine, and the color is not realistic, adjust the brightness, the range of change is significantly reduced, black and white images have other noise. This difference is also an important method for refurbishing machines.
