For reasons of quality and the use of visual effects, many of the televisions are now not only liquid crystal televisions, which have a high life expectancy, but are also good for value, but later, because of time-use reasons or inappropriate maintenance operations, inappropriate methods, etc., and may lead to a series of sites that need to be repaired, so can consumers handle this at this time, in addition to commissioning professional after-sales service providers? Examples of techniques and common sense in the maintenance of lcd televisions are provided in the following minor compilations。
I. Common failures of lcd tv and maintenance methods
1. A normal white screen for tv on
If this is the case with lcd tv, it is most likely due to poor intra-television line contact. 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。
From the examples and analyses above, we can see that lcd television is likely to have a series of problems, such as lack of access to programmes or difficulties in operating, because of inadequate maintenance or inadequate after-sales services. At this point in time, the authors believe that there are many options available to them, such as recourse to specialized services or, in case of emergency, taking into account the above-mentioned expertise, to operate in the light of their own circumstances and to deal effectively with the problems in question with their own experience and patience in order to achieve satisfactory results, as well as reducing the costs and costs of maintenance。
