The LCD screen of LCD is very fragile! The surface of the screen may be damaged if it is slightly forced by hand. We usually say that there are no more than two cases of screen failure. One is hard surface contusion. Such as surface scratch, broken screen, or liquid crystal overflow. It can't be fixed. This kind of screen is broken. There is no need to replace it with a new one. Because the price of one screen accounts for 80% of the total price of LCD, nearly 1000 yuan.

How can sharp also have this kind of fault? It's usually the domestic machine. The main problem is that the domestic machine is all assembled with imported screen and core motherboard. It's often not a supplier's thing, so it has the problem of component compatibility. It's also good to restart after the fault occurs. Even the manufacturer's maintenance station can't judge and deal with this situation. It's only necessary to replace different batches of machines. Anyway, it's a fault.

Think twice. If sharp's LCD TVs go crazy, I'm afraid there will be a problem. It's better to buy a home-made one. At the same price, the panel is still hard screen. It's a little more reassuring than the screen of unknown origin.

We bought Samsung's 40 inch LCD TV in May 2009 (it was only used in early July). In September 2010, the TV appeared black screen phenomenon ~ ~ the maintenance personnel came to the door to check that the power supply board was broken and needed to be replaced. It cost 600 yuan. After more than a year, the power panel broke down and could not be repaired but replaced. We really couldn't accept it, so we complained to the industry and Commerce Department. After coordination, the headquarters agreed to replace the power panel for us at a price of 500 yuan, and promised to arrange maintenance personnel to provide on-site service within seven days. But seven days later, we didn't see anyone. We contacted Samsung and said that we had to pay a deposit of 300 yuan before we could replace it five days later. What's more, it's even more irritating,
