What are the reasons why the led backlight strip doesn’t work?
1. The packaging protection of LED light strip is not perfect, which causes the light bead to be damaged by impact during transportation
2. The welding point of the LED light bar has faulty soldering. The vibration in the transportation process causes the welding point to fall off and the light bar does not light
What are the reasons why the led backlight strip doesn’t work?
3. The soldering amount of LED light bar is small, and the soldering point is easy to fall off
4. The soldering quality of LED light bar is not good. The solder joint of LED flexible light bar is prone to brittle crack and falling off during bending
5. When the LED light bar is installed, the bending angle is too large, resulting in the separation of the LED flexible light bar solder joint from the copper foil, which leads to the failure of lighting
6. The LED flexible light bar chip is damaged or the solder joint is deformed and falls off due to excessive extrusion of the product during the installation of the LED light bar
What are the reasons why the led backlight strip doesn’t work?
7. The soldering resistance layer of LED light strip circuit board is too thick, and the soldering tin and circuit board cannot be completely fused during soldering, which is also a phenomenon of faulty soldering
8. The LED light bar shall not be twisted during installation. If it is twisted, the solder joint of the LED flexible light bar will fall off and the light will not light
