Dead or Stuck LEDs<\/h3>\n<p>The most common cause. Each LED is a tiny light. If one fails, it creates a black spot.<\/p>\n<p><strong>Why LEDs fail:<\/strong><\/p>\n<ul>\n<li>\n<p>Manufacturing defect<\/p>\n<\/li>\n<li>\n<p>Static electricity damage<\/p>\n<\/li>\n<li>\n<p>Old age (end of lifespan)<\/p>\n<\/li>\n<li>\n<p>Overheating<\/p>\n<\/li>\n<li>\n<p>Power surge<\/p>\n<\/li>\n<\/ul>\n<h3>2. Physical Impact<\/h3>\n<p>Dropping a module or hitting the screen can break individual LEDs.<\/p>\n<p><strong>Common scenarios:<\/strong><\/p>\n<ul>\n<li>\n<p>During transport (rental screens)<\/p>\n<\/li>\n<li>\n<p>During installation<\/p>\n<\/li>\n<li>\n<p>Accidental impact (balls, tools)<\/p>\n<\/li>\n<li>\n<p>Cleaning with too much pressure<\/p>\n<\/li>\n<\/ul>\n<h3>3. Moisture Damage<\/h3>\n<p>Water ingress can short-circuit LED drivers.<\/p>\n<p><strong>How moisture gets in:<\/strong><\/p>\n<ul>\n<li>\n<p>Cleaning with wet cloth (liquid seepage)<\/p>\n<\/li>\n<li>\n<p>Rain (outdoor screens with failed seals)<\/p>\n<\/li>\n<li>\n<p>High humidity environments<\/p>\n<\/li>\n<\/ul>\n<h3>4. Driver IC Failure<\/h3>\n<p>The driver IC controls multiple LEDs. If it fails, a whole section may go dark.<\/p>\n<p><strong>Signs of driver failure:<\/strong><\/p>\n<ul>\n<li>\n<p>Row or column of dead pixels<\/p>\n<\/li>\n<li>\n<p>Larger dark patch (not a single dot)<\/p>\n<\/li>\n<\/ul>\n<h3>5. Loose Cables or Connections<\/h3>\n<p>Sometimes the issue is not the LED itself but the connection.<\/p>\n<p><strong>Common culprits:<\/strong><\/p>\n<ul>\n<li>\n<p>Loose ribbon cable between modules<\/p>\n<\/li>\n<li>\n<p>Faulty receiving card<\/p>\n<\/li>\n<li>\n<p>Loose power connector<\/p>\n<\/li>\n<\/ul>\n<h2 style=\"text-align: center;\">Step-by-Step Troubleshooting<\/h2>\n<p>Before assuming the worst, try these safe diagnostic steps.<\/p>\n<h3>Step 1: Identify the Pattern<\/h3>\n<div class=\"table-scroll\">\n<table>\n<tbody>\n<tr>\n<td>Pattern<\/td>\n<td>Likely cause<\/td>\n<\/tr>\n<tr>\n<td>Single black dot<\/td>\n<td>One dead LED<\/td>\n<\/tr>\n<tr>\n<td>Small cluster (2-5 dots)<\/td>\n<td>Localized module issue<\/td>\n<\/tr>\n<tr>\n<td>Row or column of black dots<\/td>\n<td>Driver IC or cable issue<\/td>\n<\/tr>\n<tr>\n<td>Large dark patch<\/td>\n<td>Module failure or power issue<\/td>\n<\/tr>\n<tr>\n<td>Spot visible when screen off<\/td>\n<td>Physical damage (crack, burn)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h3>Step 2: Try a Power Cycle<\/h3>\n<p>Sometimes the issue is temporary.<\/p>\n<p><strong>How to power cycle:<\/strong><\/p>\n<ol start=\"1\">\n<li>\n<p>Turn off the screen<\/p>\n<\/li>\n<li>\n<p>Unplug from power<\/p>\n<\/li>\n<li>\n<p>Wait 30 seconds<\/p>\n<\/li>\n<li>\n<p>Plug back in<\/p>\n<\/li>\n<li>\n<p>Turn on<\/p>\n<\/li>\n<\/ol>\n<p><strong>If the black spot disappears<\/strong>\u00a0\u2192 temporary glitch, fixed.<br \/><strong>If it remains<\/strong>\u00a0\u2192 permanent issue, proceed.<\/p>\n<h3>Step 3: Run a Full-White Test<\/h3>\n<p>Set the screen to display full white.<\/p>\n<p><strong>What to look for:<\/strong><\/p>\n<ul>\n<li>\n<p>Black spots are most visible on white<\/p>\n<\/li>\n<li>\n<p>You can see the exact shape and size<\/p>\n<\/li>\n<li>\n<p>You can count how many pixels are affected<\/p>\n<\/li>\n<\/ul>\n<h3>Step 4: Check for Physical Damage<\/h3>\n<p>Inspect the screen surface closely.<\/p>\n<p><strong>Signs of physical damage:<\/strong><\/p>\n<ul>\n<li>\n<p>Crack in the epoxy or plastic surface<\/p>\n<\/li>\n<li>\n<p>Dent or impact mark<\/p>\n<\/li>\n<li>\n<p>Discoloration around the spot<\/p>\n<\/li>\n<\/ul>\n<p><strong>If you see physical damage:<\/strong>\u00a0The module needs replacement.

Try the gentle pressure method or pixel refresh software. However, most dead pixels cannot be revived and require module replacement.<\/p>\n<\/details><details>\n<summary>Q: Will black spots spread to other pixels?<\/summary>\n<p>No, dead pixels typically do not spread. However, if the cause is driver IC failure or moisture damage, other pixels may fail over time. Replace the affected module to be safe.<\/p>\n<\/details><details>\n<summary>Q: How do I prevent black spots on rental screens?<\/summary>\n<p>Use padded flight cases, handle modules carefully during setup\/teardown, inspect before and after each rental, and keep spare modules in your kit.<\/p>\n<\/details><details>\n<summary>Q: Does warranty cover dead pixels?<\/summary>\n<p>Most warranties cover excessive dead pixels (typically more than 3-5 per module) but may not cover a single dead pixel. Check your warranty terms. IvanLED offers 1-year warranty on modules.<\/p>\n<\/details><details>\n<summary>Q: How do I know if it is a dead pixel or stuck pixel?<\/summary>\n<p>A dead pixel is permanently black. A stuck pixel may be black, white, or colored and sometimes can be revived with gentle pressure or software. Run a full-color test (red, green, blue, white) to see how the pixel responds.<\/p>\n<\/details><details>\n<summary>Q: Can cleaning cause black spots?<\/summary>\n<p>Yes. Spraying liquid directly on the screen or using too much pressure can cause moisture damage or physical damage. Always spray on cloth first and use gentle pressure.<\/p>\n<\/details>\n<h2 style=\"text-align: center;\">Need Help with Black Spots?<\/h2>\n<p>At\u00a0<a href=\"https:\/\/www.ivanled.com\/about\/\"><strong>IvanLED<\/strong><\/a>, we provide technical support and replacement modules for all our displays.<\/p>\n<p><strong>What we offer:<\/strong><\/p>\n<ul>\n<li>\n<p>Troubleshooting assistance via WhatsApp<\/p>\n<\/li>\n<li>\n<p>Replacement modules (keep spares on hand)<\/p>\n<\/li>\n<li>\n<p>Receiving cards and cables<\/p>\n<\/li>\n<li>\n<p>1-year warranty<\/p>\n<\/li>\n<\/ul>\n<p><em><a href=\"https:\/\/www.ivanled.com\/contact-us\/\">Send us<\/a> a photo of the black spots.
