Troubleshooting
One pixel went dark. Here is what happens next.
A single dead pixel on a Thraxel roofline does not take the strip down with it. Each pixel is individually addressable, so we can diagnose the one that failed and typically replace it the same day. Most of the time you do not need to do anything but tell us.
Why one dark pixel is not a big deal
Old string lights failed in series. One bad bulb and half the roofline went black, and you spent an evening on a ladder swapping bulbs until you found it. Permanent pixel systems do not work that way. Every pixel on the track has its own address on the data line, so when one stops responding the rest keep running the scene as if nothing happened.
That same addressing is what makes the fix simple. Because the controller talks to each pixel by number, we can see from the pattern of what is lit and what is not exactly where the fault sits. There is no guessing and no pulling the whole run apart to find it.
On a typical 168-LED install, one pixel is well under one percent of the roofline. From the street most people never notice it. We still want to know about it, because a pixel that fails early can point to something worth checking before winter.
What you can check in five minutes
Before you assume the pixel is dead, rule out the cheap explanations. Open the Thraxel Lighting app and run a solid white scene across the whole house. A pixel that is off in a color scene but on in white is not broken, it was just assigned a dark spot in that pattern. Music sync and chase scenes turn individual pixels off on purpose.
If it is still dark on solid white, look at the pixels next to it. A single dead pixel with everything after it still lit is almost always the pixel itself. A dead pixel with everything after it dead too is a data or power break, which is a different repair and one we want to see in person.
- Run a solid white scene, not a pattern
- Confirm the dark spot is a pixel and not a shadow from a gutter or downspout
- Note whether the pixels after it are lit or dark
- Take a phone photo from the sidewalk at night
- Leave the track alone, do not pry at the silicone
What usually kills a pixel
Honest answer: not much. The pixels we install sit in IP67 marine-grade silicone on 16-gauge wire and are salt-tested for river-town air. Water intrusion, which is the number one killer of cheap kit lighting, is rare on a properly sealed run. When we do see a failure, it is usually one of three things.
The first is a manufacturing defect that shows up in the first few weeks, which is exactly what the parts warranty exists for. The second is physical damage, a ladder against the fascia, a contractor cutting into the track during a gutter job, a limb coming down in a storm. The third is a connector that took a hit during a freeze-thaw cycle and let moisture in. Each one is fixable, and each one is a single-point repair rather than a rebuild.
How the replacement works
You text or call Tyson at 724-859-4390 with the photo and where on the house it is. He is the same person who quoted and installed the system, so there is no ticket queue and nobody reading a script. Most of the time he can tell you from the photo whether it is a pixel or a break.
For a pixel, replacements are typically same-day inside our daily route across the 16xxx ZIP codes, and quick to schedule for the rest of the footprint. The crew opens the track at that section, cuts out the failed pixel, splices in a new one, reseals, and confirms it responds in the app. You get the final look from the driveway before they leave, just like install day.
During the warranty window, 3 years on parts and 1 year on labor, this costs you nothing. After that, it is a small service call. The details of what is and is not covered are on thraxel.com/warranty/ and in thraxel.com/blog/what-the-3-year-parts-warranty-covers/.
When a dark pixel means something bigger
A run of dark pixels that starts at one point and continues to the end of the zone is a data or power break, not a bad pixel. Common causes in Western PA are ice pulling on a connector, a rodent chewing through a lead near the ground, or a downspout replacement that pinched the wire. We treat those as a priority because the break can let water in and take out more pixels over time.
Random flicker across a whole zone, or pixels showing the wrong color, is usually a controller or power issue rather than a pixel issue. Power-cycle the controller first. If the flicker comes back, that is a call, and thraxel.com/blog/controller-reset-and-wifi-issues/ walks through what we check.
Why we designed it this way
We hung seasonal Christmas lights for years as 160 Glow before we became Thraxel, and we spent a lot of Decembers hunting down one bad bulb on a cold roof. Individually addressable pixels in a sealed track were the answer to that problem, and same-day single-pixel replacement is the service that makes the answer stick.
If you are still deciding on a system, the pixel story is worth weighing. Ask any installer how they find and fix one dead light, and how long you wait. The full spec of what we install is at thraxel.com/permanent/, and the free consult is where you can see the demo case and push on the details.
