Acrylic luminous characters are increasingly becoming one of the common products in urban streets. Luminous characters will be damaged more or less after a long time, especially for a business card in urban streets. Shop luminous characters are very important products at night, but it must be a headache for non professionals. Today's editor will teach you seven easy to understand solutions:
1、 First of all, check whether the luminous word is not on as a whole or partially? Or is it flashing?
2、 Let's start with the glint problem which is easier to solve.
1. Fault location: this situation is that the switching power supply of the luminous word is damaged, and the problem can be solved by replacing a new one.
2. Fault reason: the power of the bad power supply is too small, the power consumption of the luminous word is too large, resulting in the overload of the power supply and damage.
3. Maintenance suggestion: replace the switch power supply with higher power, so as to avoid repeated failures.
3、 Please check the switch power supply of the luminous word first.
1. Location of switching power supply: generally, the switching power supply will be installed near the back of the luminous word, which is not far away from the hidden, beautiful and convenient for maintenance. As long as we carefully follow the luminous word to the back, it should not be difficult. After all, the staff of the advertising company will consider the above principles for fixing.
2. Check method 1: general switching power supply will have an LED indicator is on, there are also a few not on but also good phenomenon, only a single LED indicator is damaged; but it can not be on if it is broken?
3. Check method 2: switching power supply under normal working condition is different degrees of noise, one is the sound of the cooling fan, the other is the weak sound of electronic components.
4. Inspection method 3: after a period of power on, the shell of normal switching power supply will produce a certain amount of heat. No heat is bad.
4、 If the switching power supply can work normally after being removed, it means that there is no problem with the switching power supply.
1. First check whether the indoor control switch is normal
2. Is the wire from the control switch to the switching power supply burnt out,
3. Whether there is a timer, whether there is a display on the timer screen, and check whether the No. 7 battery on the timer is exhausted. If there is no display after replacing the battery, the timer will be damaged. You can not use the timer first.
4. Solution: the household appliance test pen can be used to check whether the N and l poles of the switching power supply are powered on to eliminate the above faults.
5、 Load short circuit: that is, there are two cases of short circuit between LED lamp beads or switching power supply and LED lamp beads. If there is a short circuit, the switching power supply will not work. The high-quality switching power supply will automatically cut off the power for protection. If the cheap switching power supply does not have this function, it will directly cause the electronic components to burn or catch fire.
1. Check whether there is positive and negative contact between the lines, separate them and wrap them with electrical insulation and glue.
2. Check if the lamp beads are soaked in water.
6、 If the brightness of the light-emitting words is not enough, it is obvious that the light and dark areas are displayed, and most of the light-emitting words are aging. Skip to step 7 directly.
7、 Direct consultation with Hongchen advertising technical engineer to solve the fundamental problem in one step!
