1. Has the boot character been blurred and gradually becomes clear? Is this normal?
First of all, tell everyone that if your monitor also has this problem, then you have to prepare for your monitor "after the incident." Because this situation is a precursor to display aging.
In principle, the electron gun of the cathode tube in the lacquer must be heated before the electron beam can be emitted. However, when the cathode tube starts to age, the heating process becomes slow. Therefore, when the cathode ray tube is turned on, the cathode tube does not reach the standard temperature. We couldn't shoot enough electron beams, so the picture we saw at the moment would not be clear because we didn't have enough electron beams to strike the screen. After prolonged use, the temperature reached the standard, and a sufficient amount of electron beam bombarded the phosphor to make the display clear. This situation generally occurs after the purchase of monitors for many years, there is no need for maintenance, you can buy a separate monitor. If this is a problem with the new monitor, it indicates that the aircraft has had signs of aging. It may be a renewal of the picture tube and it is recommended to return it immediately.
2. Clear and fuzzy first, why?
From the principle analysis, the cause of this phenomenon is mainly focused on the circuit, it may be caused by poor heat dissipation. The first is that there is a problem with the focus circuit design, which can not guarantee its normal operation after prolonged use, resulting in image blur; secondly, due to poor heat dissipation, the line tube is too hot, resulting in output power loss, and then affecting the high voltage output and acceleration. The level voltage output is insufficient, thereby affecting the normal operation of the focus circuit. In fact, the focus is on the circuit.
Solution: Open the back cover of the monitor with a knob that adjusts the high pressure. However, this solution is only effective for a short period of time. Operating the monitor for a long time to adjust the high voltage will accelerate the aging of the display. If the monitor is used for a long time, it will still result in poor focus. If this monitor has been in service for many years, it can be used to make its final calories in life; however, if it is a newly purchased display, it must be replaced as soon as possible.
3. What to do if the monitor is lacking in color?
Because the display relies on the decoding circuit to separate the colors, the problem of lack of color occurs, the basic fault is determined on this circuit, and the circuit can be replaced. However, some hidden problems may also cause lack of color, which is very difficult to distinguish and repair, the author of the monitor because of the display signal line has led to lack of color, resulting in an unusually complex repair process, and took many detours.
Solution: Because the lack of color involves the replacement and maintenance of the circuit board, or even the replacement of some components such as capacitor resistance, such problems should immediately go to a professional display repair center to test, if it is a new monitor, it should be replaced immediately.
