During the maintenance of the different tv components, the prices varied, and when the general maintenance of the lcd television was carried out, its basic maintenance costs were 120, 140, 160, 200, 260, 280 dollars, which were defined on the basis of different maintenance projects: 14-15, 17-20, 26-30, 32-40, 42-47, 50-52 per cent, and 30 per cent of the basic maintenance costs, if the television was struck or if there was a failure after entering the water. The basic item, 14-15, was at a price of $70 when replacing ssb plates。
Ii. Disaggregation of lcd television maintenance failure
1. In the course of the use of lcd tv, if there is a problem with no sound or image on the television, and the television light flashes and turns into a long light, the television flashes white light at the moment when it is on, the failure of the television should be due to the damage to the backlight drive of the television, but it is not precluded by the problem of the television backlight tube。
2. There was no sound, no image, no light after the television was turned on. This failure should be due, first and foremost, to problems with the power panels and, again, possibly due to the irregularity of the cpu component of the television。
3. While the television sets appear to be on screen after they are on, the sound of the television shows normality, which should be due to poor digitized panels of the television, and the second to poor contact with the link in the machine。
4. Television lights cannot turn on. The failure of this lcd television should be distinguished by the fact that the cpu bus on the tv is not working properly or by the ic exposure of lcd tv。
Iii. Lcd tv maintenance - troubleshooting
1. There is a problem with the screen-full patches or the screen-sequenced vertical bars that are normally television buffers, at which point a pair of buffers can be replaced or a failure of the ic line can be measured。
The most vulnerable problems of lcd television are the dark bands and wires, which can be summarized as a television screen when such problems arise. This may be due to the separation of the link points between the cof and the screen of lcd tv as a result of the high temperature of the television, which can be repaired using a flat-head iron-bed insulation medium。
3. In the case of lcd television, which is connected to the turn-on, but after a certain period of time, the lack of light and sound is generally due to the failure of the reverse circuits of the television screen components, in addition to the ageing of the television pv or damage to its high voltage panels. At this point, maintenance can be performed using the elimination of the average of the pressure plate feedback into the circuit to determine whether the pressure plate itself is in question。
In addition to analysing the maintenance rates for lcd tv, we started with several sections of the breakdown method. From the above perspective of professionals, it is believed that it is possible to understand that the failure of lcd television varies according to its specific manifestations and that there are multiple categories under its umbrella, so that steps towards exclusion are essential. In addition, we need to have a basic knowledge base to facilitate timely resolution of possible problems with lcd televisions in order to prevent their use。
