Many times we watch kanja tv and black screens, which affect the mood for television, many consumers are not aware of the cost of building and maintenance of conja tv, mainly because the maintenance industry has not yet had a maintenance fee, not only for television, but also for other electricity, and this has also created a phenomenon in which individual mechanics sit on the floor at a price to make the market gassy, so that today's small editor shares some of the fees for maintenance of the conja television set up online for information purposes, so that they will not be buried while the tv is being repaired, and there will be a number of them。
I. Cost of television maintenance at kanja
The general maintenance cost is 100+, depending on the size of the television. If you change the whole panel, it's about $300-500. 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。
