It is believed that many people have experienced this situation in their daily lives, when the television is turned on or is being watched, suddenly white screens appear. This is usually the case, where we're used to turning off television, cutting off electricity and sometimes returning to normal, sometimes not. In fact, as long as this happens, it is generally possible to conclude that there has been a malfunction, and as to which components there is a problem, we also need to conduct a specific check. In fact, there are frequent failures on television, which have a lot to do with usage, and we can try to do the following sort of thing first, and then we can do something about it。
First, to check first if there is any poor exposure to the power outlets on the screen, which is generally a low probability but still exists. It will then follow the power supply line, where it may be necessary to remove the back of the television cover and carefully screen all plugs for any loose ageing。
Second, check if the cathode is abnormal. One of the problems that used to be used in the past was the burning of the cathodes, which would appear on the screen and could be solved by replacing the catheters。
Third, there is no problem with screen power, no problem with access points, no problem with the cadets, and it is likely that there is a problem with one of the electronic components of the circuit boards. It needs to be used here. (b) short-linking of the convulsions of circuit boards with the tensile gauge, which determines the state of the convulsions. There is also a need to check whether there is a problem with the signal output of the main plate and the connection line of the screen to see whether the line is exposed to poor or aging。
In fact, colour televisions are relatively simple in their internal structure compared to smart televisions, which are now more common. Some of the circuits and some of the maintenance experience are self-serviceable. If colour electricity is often problematic, it is a matter of usage. For example, when it's off, you don't need a remote, you pull the power. Or it's used in hot, wet environments. There are large power appliances in the vicinity of television, or the same lines as large power appliances. These are poor usage habits, which increase significantly the probability of television failure and require special attention。
