Samsung is what we know, and samsung phones are the preferred choice for many of us. Of course, with the exception of mobile phones, samsung has performed very well in many areas, of which television is one. Samsung's monitors are very famous, and they're very good on television, but after we've spent a long time, we'll have some troubles. How much is it gonna cost us to fix it? Three-star tv maintenance fee is how much, never get fucked。
I. Common trouble resolution
1. Liquid crystal screen failure
Screen failures, such as break-ups, dark screens, black screens, white screens, etc.; screen display failures usually occur in the screens with crosses, vertical lines, bright wires, dark lines, etc.; screen content failures are mainly image colours, rasters, etc。
2. Main drive failure
The switch is without image, without a raster, without an acoustic sound, without a power signal light, without a light flash, without a cold machine, etc.; without voice, without voice, without voice; without sound, without sound, without image black screen, without flower screen, etc。
Ii. How to complete
1. Barrier detection methods
In the absence of electricity from the logical plate, tests are conducted primarily to check whether the safety resistance on the logical board is open, whether the source foot and ground of the relevant integrated circuit on the logical plate are punctured, and whether the tripolar tube on the logical board is leaked or not。
3. Electricity test methods
The up-to-screen test primarily detects the following critical points, checking whether the upper-screen voltage is normal, with variations in the upper-screen voltage of different models, with the upper-screen voltage being mainly 5v or 12v. Checks whether the supply of 3. 3 v, 2. 5 v or 1. 8 v generated on the dc/dc conversion circuits on the logboard is normal; the labels of different screen manufacturers vary, e. G., 3. 3 v on the aut420hw04 screen logic board is indicated as “v3d3”. Checks whether the vda voltage generated by the dc/dc conversion circuit on the logical board is normal, usually around 15. 8 v。
Maintenance costs
This cost, which relates to the size of the television, is approximately $300 for the maintenance of a 50-inch television. It costs $30 within 30 kilometres and $400 for maintenance. Spare parts for what? When the main plate is broken, the main plate is about 1,000, the cost of using more components is high, the cost of maintenance is high, and some need to be replaced by the whole plate, such as the power plate and the main panel, about $300。
