In indoor lighting, metal halide lamps are a common lighting equipment. However, it is not always easy to diagnose a metal halide lamp failure. This article will introduce common faults of metal halide lamps and provide some judgments and solutions.
When you turn on the switch and the metal halide lamp does not respond, there are several possible reasons:
1. Check whether the power supply is connected properly. Confirm whether the power cord is plugged in properly and check whether the fuse in the distribution box is normal. 2. Check whether the bulb is installed correctly. Sometimes, the bulb of a metal halide lamp is not securely connected, causing it to fail to light. Check and reinstall light bulb. 3. Check whether the voltage is normal. Use a voltmeter to measure whether the voltage reaches the required operating voltage range of the metal halide lamp. 4. Check whether the circuit is damaged. If the circuit to which the metal halide lamp is connected is damaged, it may not light up properly. Damaged circuits need to be repaired or replaced.Frequent flashing of metal halide lamps may be caused by the following reasons:
1. Poor contact of the bulb. Confirm that the bulb is installed correctly and that the lamp socket has good contact. 2. The power supply voltage is unstable. Check if the power supply voltage is stable, if not, you need to fix the power supply problem. 3. Poor circuit contact. Check whether the circuit connection of the metal halide lamp is good and make sure the circuit contact is good. 4. The bulb is aging. The life of the bulb is limited and if the metal halide lamp is used for a long time, the bulb may need to be replaced.If you notice that the metal halide lamp makes noise, it may be caused by the following reasons:
1. The bulb is unstable. Check whether the bulb of the metal halide lamp is installed correctly and whether the bulb is loose or damaged. 2. The power supply voltage is unstable. Unstable power supply voltage can cause metal halide lamps to emit noise. Check the power supply voltage and fix voltage instability issues. 3. Circuit problem. There may be a problem with the circuit to which the metal halide lamp is connected, and the damaged circuit needs to be inspected and repaired. 4. The bulb is aging. Lamps that have been used for a long time may produce noise and require replacement.The uneven brightness of metal halide lamps may be caused by the following reasons:
1. The life of the bulb is different. If the bulbs in the metal halide lamp are used for different times, uneven brightness will result. All bulbs need to be replaced to maintain consistent brightness. 2. The light bulbs are installed at different heights. Metal halide lamp bulbs installed at different heights may cause uneven light distribution. Check and adjust the lamp installation position. 3. The reflector or reflector is damaged. Damage to the reflector or reflector of the metal halide lamp will affect the uniform distribution of brightness, and the damaged parts need to be replaced.It is not always easy to diagnose metal halide lamp faults, but by checking the power connection, bulb installation, voltage stability and circuit connections, we can find solutions to many common faults. If the above methods cannot solve the fault, it is recommended to ask professionals for repair and testing.
Hello, based on the content of the malfunction you mentioned, I roughly guess that your computer is a laptop, and it is also a product with a touch screen function.
If my guess is correct, then your fault can basically be traced to an incorrect touch problem on the touch screen (the circle is the feedback of the system click, and the box is the feedback of the touch frame selection). This is basically a hardware failure, which can basically only be cured by replacing the touch screen.
It was repaired before. In fact, it is most likely that the person did not install the touch screen driver intentionally or unintentionally (the touch screen without driver does not work), so the appearance is; however, win10 system (some hardware can also be used in win7 system) will be in the system During the update, the touch screen driver that was not installed will be installed for you (the touch screen will start working again), so.
If you don’t want to spend money to replace the screen, and the touch screen is of little use to you, the most convenient temporary solution at present is to find the hardware corresponding to the touch screen in the device manager and disable it. Can.
1) If there are spots on the entire screen and distorted graphics and images, it is usually because the driver loader is wrong. Recheck the driver loader. If uninstallation and reinstallation are not possible.
(2) There is another possibility that the sending card is broken. At this time, the sending card needs to be replaced.
(3) If it flashes irregularly, it is usually a system frequency problem. Changing the system or adjusting the setting parameters can basically solve the problem! If it is flickering, it may be a graphics card driver problem or a sending card resolution setting problem. Another possibility is the power supply problem (insufficient power supply, information clutter, electromagnetic interference). When designing the PCB, more consideration should be given to the wire diameter of the power supply and signal traces, as well as the PCB production process. Adding a few more capacitors to the module will also improve things.
(4) If the text is flickering (there are irregular white edges around the text, irregular flickering, and the text disappears and then disappears), this is a problem with the graphics card settings. In the display properties, cancel "Show hidden shadow under menu" and "Edge" Smooth transition effect" can solve such problems.
