The modern TV is a whole world of entertainment and recreation for the whole family. With advanced features, you can watch your favorite programs, play games, check emails, etc. on it. It is necessary to test the TV before buying in order for it to bring joy to the household and to work for a long time.
Instructions
Step 1
Not all electronics stores have a “customer is always right” formula. Therefore, when purchasing equipment, check for a quality certificate and manufacturer's warranty. Check with the store administrator if it will be possible to return or exchange the TV if the defect is found already at home.
Step 2
If you find a suitable store and choose a TV, then you need to check the packaging and contents. Examine the protective films on the TV cabinet carefully. Check for remote control, cable and documentation.
Step 3
If the protective films have already been removed, and scratches and other damages are visible on the case, then you should refuse to purchase. Most likely, such a TV has already been under repair or it is a "display case". Such a model should be sold with discounts and corresponding marks on the price tag.
Step 4
Before going to the store, download a selection of test pictures to any media to check the TV. When purchasing, connect the USB flash drive to the device. Turn on the TV and select the media player mode from the menu. Turn on image viewing and experience the display. Full-screen images in different colors help identify bad pixels. On a solid-colored background, a “broken” pixel looks like a black non-luminous point. A hot pixel on the screen appears as a colored dot even in a black image.
Step 5
A black background reveals uneven illumination. If you notice a lot of light spots on such a background, then you need to refuse to buy such a TV. When watching your favorite movie, light areas will be uncomfortable. In addition, many TV manufacturers do not consider this backlight to be a defect. A white filled image can help you identify spots of color on your TV screen. Such a defect is called "tint" - a color in the matrix that is present on top of the main picture.
Step 6
You can also check the speakers built into the TV. If the sound is bad, you will not get the joy of watching your favorite show. Therefore, start a melody from a flash drive on the TV and listen carefully. The speakers should not wheeze, the sound should be clear when playing.
Step 7
Many modern TVs have built-in Wi-Fi. At the store, connect to the network and check the connection. Try loading a page on the internet. If you have trouble connecting, please contact your dealer for help. If the built-in Wi-Fi is working, the TV will display the page.
