In many homes, we find that there's a television set in the living room, not only as a tool to help people enjoy their leisure time, but also as a platform for family and friends to communicate peacefully, so the importance of the role of television is self-evident, but an analysis of the actual situation shows that the method used is inappropriate, or that failure to maintain repairs leads to some malfunctions in the television set, which will affect its use later on, so is it possible at this point to learn the relevant maintenance techniques, in addition to having recourse to specialized institutions?
I. Maintenance of tv methods
The general solution to the television failure:
1. Examination of television malfunctions, i. E., their performance;
2. Lines or spare parts that are prima facie faulty based on the performance of the television;
3. Individual testing and checking of suspected fault lines and parts, using specialized tools such as the universal table;
Once the faulty circuits and spare parts have been identified, the circuits are reconnected and the failure of the spare parts is replaced by the corresponding type of spare parts;
5. Televisions can normally be restored after replacement by maintenance of fault lines or spare parts; however, since the maintenance of televisions requires professional knowledge and tools, it is recommended that they should not be self-destructive and that they should be thoroughly tested and repaired in a timely manner in connection with after-sale services。
Ii. Examples
1. A normal white screen for tv on
If this happens, it's probably due to poor cable contact inside the tv. Because within lcd television, the various assistance is built in a long, high-temperature working environment, which can easily lead to poor exposure. The solution to this situation would be to remove the lines and re-integrate them. And before you re-plug it, you can use tape to stick it to the shelf of the cable and the tv slot, so it won't be easy to touch, and the tv won't be white screen。
Two, no tv or jump
If this is the case with lcd tv, it is likely that there is a local short-circuit failure of lcd keys, which, although more likely, is only a small problem, with only new or good keys to remove the failure, so there is no problem. When changing keys, attention can be drawn to whether the voltage of the following televisions is normal, which may also affect the television closing。
Three, three, three, no power lights
The lcd televisions are open, the power lights are not on, and in general the power is not delivered to the tv board sz, or the television panel is malfunctioning. When power panels fail, they often lead to power-free output, so televisions do not accept power input, there is no natural starter, and no power lights. Just get a good power panel. This is also the case when the cpu part of the tv is not working properly and this situation requires careful scrutiny of the cpu on tv before a decision is taken。
4-television turned on with a sound display
If this is the case with lcd tv, it is likely that the voice image processing of the television is largely normal, and that the screen failure may be caused by the abnormality of the power supply of the screen lamp. In this case, it is first necessary to check whether the television power supply to the pressurized plate is 12v, and, if not, whether l503 is normal for it. If the l503 output voltage is clear and the television screen is still not bright, it may be that the television pressurized panel is malfunctioning and can be replaced by a new pressurized panel, and if the screen is still not bright, the screen is broken and the television screen is replaced。
While the importance of television for us is self-evident, problems may arise in real life because of the inappropriate use of the method or the quality of the product itself, such as the inability of the television to open or the abnormal sound quality of the product. At this point, in addition to having recourse to specialized maintenance agencies for processing, and in order to minimize the costs and costs of maintenance, we can also learn the techniques involved, such as the one described above, which is extremely useful paper, and which is suitable for a friend with a learning interest to learn more about the analysis in order to develop a viable methodology。
