Troubleshooting Guide"},"content":{"rendered":"<article style=\"max-width: 800px; margin: 0 auto; padding: 20px; font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Helvetica, Arial, sans-serif; line-height: 1.8; color: #333; text-align: left;\">\n\n  <p style=\"text-align: left; margin-bottom: 20px;\">Fountain lights not turning on is one of the most common operational issues and also one of the repair scenarios where it\u2019s easiest to take the wrong approach. The bottom line: Just because a light isn\u2019t working doesn\u2019t mean it\u2019s broken. Wiring issues, a faulty driver, or an interrupted DMX signal can all cause lights to fail. Blindly replacing lights not only wastes money but may also result in the lights still not working\u2014because the root cause was never identified. The correct approach is to troubleshoot step-by-step in the order of \u201dcheck the wiring first, then the driver, and finally the fixture.\u201d The 5-step diagnostic method can pinpoint the cause of 90% or higher faults within 30 minutes.<\/p>\n\n  <h2 style=\"font-size: 22px; color: #1a1a1a; border-left: 4px solid #007cba; padding-left: 10px; margin-top: 35px; margin-bottom: 20px; text-align: left;\">Confirmation of Basic Information Prior to Diagnosis<\/h2>\n  <p style=\"text-align: left; margin-bottom: 20px;\">Before you begin troubleshooting, verify the following basic information to narrow down the issue\u2014no equipment is needed:<\/p>\n  <ul style=\"padding-left: 20px; margin-bottom: 20px; text-align: left; list-style-type: disc;\">\n    <li style=\"margin-bottom: 8px; text-align: left;\"><strong>Scope of the Malfunction:<\/strong>Is it just one light, a few lights, or a large number of lights not working in a specific area?<\/li>\n    <li style=\"margin-bottom: 8px; text-align: left;\"><strong>Failure Modes:<\/strong>Is the screen completely black, are some colors missing, or is the brightness too low?<\/li>\n    <li style=\"margin-bottom: 8px; text-align: left;\"><strong>Trigger Conditions:<\/strong>Did this occur after a thunderstorm, during normal operation, or after the system was shut down and restarted?<\/li>\n    <li style=\"margin-bottom: 8px; text-align: left;\"><strong>System Alert:<\/strong>Does the control system (DMX\/PLC) display any alarm messages for the corresponding area?<\/li>\n  <\/ul>\n\n  <h2 style=\"font-size: 22px; color: #1a1a1a; border-left: 4px solid #007cba; padding-left: 10px; margin-top: 35px; margin-bottom: 20px; text-align: left;\">5-Step Diagnostic Process<\/h2>\n\n  <h3 style=\"font-size: 18px; color: #333; margin-top: 25px; margin-bottom: 12px; text-align: left;\">Step 1: Distinguish Between Widespread and Isolated Faults<\/h3>\n  <p style=\"text-align: left; margin-bottom: 20px;\">If a large area of lights is not illuminating, the issue is typically related to the power supply or signal circuit; you should check the circuit breaker, ground-fault circuit interrupter (GFCI), DMX signal cables, or driver power module. If only a few individual lights are not illuminating, check the lights themselves or the local wiring first.<\/p>\n\n  <h3 style=\"font-size: 18px; color: #333; margin-top: 25px; margin-bottom: 12px; text-align: left;\">Step 2: Check the supply voltage<\/h3>\n  <p style=\"text-align: left; margin-bottom: 20px;\">Use a multimeter to measure the terminal block. If the voltage is 0 V, check for an open circuit; if the voltage is too low, check for contact resistance or insufficient wire gauge.<\/p>\n\n  <h3 style=\"font-size: 18px; color: #333; margin-top: 25px; margin-bottom: 12px; text-align: left;\">Step 3: Troubleshoot the DMX Signal<\/h3>\n  <p style=\"text-align: left; margin-bottom: 20px;\">A common reason why colored lights do not turn on is a loss of the DMX signal. Check that the connectors are properly plugged in, that the terminating resistors are installed, and that the signal frame rate is normal.<\/p>\n\n  <h3 style=\"font-size: 18px; color: #333; margin-top: 25px; margin-bottom: 12px; text-align: left;\">Step 4: Check the LED driver power supply<\/h3>\n  <p style=\"text-align: left; margin-bottom: 20px;\">Measure the drive output voltage. If the output is 0 V or the unit is too hot to touch (and the fan is not spinning), this is typically a power module failure; install surge protection before replacing it.<\/p>\n\n  <h3 style=\"font-size: 18px; color: #333; margin-top: 25px; margin-bottom: 12px; text-align: left;\">Step 5: Determine if the light fixture is physically damaged<\/h3>\n  <p style=\"text-align: left; margin-bottom: 20px;\">The final step is the light fixture itself. After confirming that the fixture is faulty (e.g., water ingress, burned-out LED chips, or a damaged built-in decoder) by swapping it with another fixture of the same model, proceed to replace the entire fixture.<\/p>\n\n  <h2 style=\"font-size: 22px; color: #1a1a1a; border-left: 4px solid #007cba; padding-left: 10px; margin-top: 35px; margin-bottom: 20px; text-align: left;\">Quick Reference for Common Failure Scenarios<\/h2>\n\n  <figure style=\"margin: 20px 0; overflow-x: auto;\">\n    <table style=\"width: 100%; border-collapse: collapse; min-width: 650px; font-size: 14px; text-align: left; border: 1px solid #e0e0e0;\">\n      <thead>\n        <tr style=\"background-color: #f7f7f7; border-bottom: 2px solid #dcdcdc;\">\n          <th style=\"padding: 12px 15px; border: 1px solid #e0e0e0; font-weight: 600;\">Fault Symptoms<\/th>\n          <th style=\"padding: 12px 15px; border: 1px solid #e0e0e0; font-weight: 600;\">The main reason<\/th>\n          <th style=\"padding: 12px 15px; border: 1px solid #e0e0e0; font-weight: 600;\">Priority Troubleshooting<\/th>\n        <\/tr>\n      <\/thead>\n      <tbody>\n        <tr style=\"border-bottom: 1px solid #e0e0e0;\"><td style=\"padding: 12px 15px; border: 1px solid #e0e0e0;\">All the lights in the entire circle went out<\/td><td style=\"padding: 12px 15px; border: 1px solid #e0e0e0;\">Circuit Breaker Trip\/Power Module Failure<\/td><td style=\"padding: 12px 15px; border: 1px solid #e0e0e0;\">Driver Output Voltage<\/td><\/tr>\n        <tr style=\"background-color: #fcfcfc;\"><td style=\"padding: 12px 15px; border: 1px solid #e0e0e0;\">Color failure (e.g., the red light does not illuminate)<\/td><td style=\"padding: 12px 15px; border: 1px solid #e0e0e0;\">Signal Error\/Channel Driver Failure<\/td><td style=\"padding: 12px 15px; border: 1px solid #e0e0e0;\">DMX Address Settings<\/td><\/tr>\n        <tr><td style=\"padding: 12px 15px; border: 1px solid #e0e0e0;\">Random Flashing<\/td><td style=\"padding: 12px 15px; border: 1px solid #e0e0e0;\">Missing Terminating Resistor\/Signal Interference<\/td><td style=\"padding: 12px 15px; border: 1px solid #e0e0e0;\">Check the 120-ohm terminating resistor<\/td><\/tr>\n      <\/tbody>\n    <\/table>\n  <\/figure>\n\n  <h2 style=\"font-size: 22px; color: #1a1a1a; border-left: 4px solid #007cba; padding-left: 10px; margin-top: 35px; margin-bottom: 20px; text-align: left;\">Frequently Asked Questions (FAQ)<\/h2>\n  <h3 style=\"font-size: 16px; color: #1a1a1a; margin-top: 20px; margin-bottom: 8px; text-align: left; font-weight: bold;\">Q: Can a light fixture still be used if water gets inside it?<\/h3>\n  <p style=\"text-align: left; margin-bottom: 15px;\">A: If there is only a slight amount of condensation, you can dry it out and replace the O-ring; if water has accumulated inside and soaked the electronic components, we recommend replacing the unit immediately to prevent further damage.<\/p>\n  \n  <h3 style=\"font-size: 16px; color: #1a1a1a; margin-top: 20px; margin-bottom: 8px; text-align: left; font-weight: bold;\">Q: How do I adjust the color if the new light fixture doesn't match the existing one?<\/h3>\n  <p style=\"text-align: left; margin-bottom: 15px;\">A: Make sure the new light matches the original model.
