Common Faults of LED Point Light Source Lamps and Their Solutions:
Fault One: After powering up, the controller's fault light blinks; the point light source does not light up, and there's no animation effect output?
Fault Two: After powering up, the controller's indicator light is normal, with signal output, but the point light source shows no effect change.
Fault Three: After connecting the controller to the lamps, the effects change but the lamps flicker while the controller's indicator light shows normal.
Solution:
(1) There is no connection between the ground wire of the controller and the lamps.
(2) The lamp's power voltage is insufficient.
(3) The effect created on the SD card is incorrect; the selected lamp chip doesn't match the actual lamp chip.
(4) The distance from the controller to the first lamp is too far (distance > 10 meters), leading to unstable signal transmission.
Fault Four: After powering up, the controller and some lights in the front work normally, but the lights in the back start malfunctioning from a certain point.
Fault Five: After powering up, the controller works normally, but the layout of lights changes abnormally, different from the designed video effects.
Solution: This is caused by the loading order of the lamps being inconsistent with the designed calibration diagram. Adjust the order and location of loading lamps according to the designed calibration diagram, or input the actual arrangement and connections of the loading lamps into the computer for reprogramming.
Fault Six: After powering on, all point light sources can be changed normally, but some point light sources display colors different from the others.
Solution: This is generally due to one of the R, G, B chips being damaged, causing the display to lose color. Simply replace the problematic point light sources.
Fault Seven: The SD card can't be formatted when copying the program?
Answer:
(1) First, confirm whether the protective switch on the side of the SD card is unlocked, with the unlocking direction towards the end of the SD card.
(2) If the protective lock is opened as required, but it still can't be formatted, most likely, the SD card reader is damaged. Please replace the SD card reader.
(3) If the above actions still don't solve the formatting issue, replace the SD card and retest.
