In many cases, when we watch tv, there will be long-window television screens and black screens, which will affect the mood for watching television. However, many consumers do not know the cost of maintaining the screens and black screens for long-window television, mainly because the household electricity maintenance industry does not have maintenance fees as yet. Not only are other television appliances the same, but there are still no clear rates. The master of maintenance sits on the floor and starts pricing, making the market for household electricity maintenance a mess. Today, for your information, some of the online collection fees for the maintenance of long rainbow television will be shared. There's something in mind when it comes to repairs。

Some offered vague offers of maintenance costs similar to “back-to-back television 400”, lcd 400 and 38 in 250”. There are no standards for lcd maintenance, different locations, different teacher prices, and be careful not to get caught. Lcd screens are generally 60-70 per cent of television prices, and after a three-year quality assurance period, there is no need to change them, so buy a new one。
