Life after installation: your LED wall in years two to five.

By year two, nobody looks at the LED wall the way they did on day one. That is exactly when the slow changes begin: a little less brightness, a tile a shade warmer than its neighbours, a warranty that ends on a date nobody wrote down. None of it is dramatic, and all of it is manageable if you see it coming. This is what years two to five of owning an LED wall really look like.

Brightness loss: slow, and rarely the first thing you notice

Every LED gives out a little less light as the hours add up. It is gradual wear, not a fault, and it happens to every LED screen. On a wall in daily use, the modules take 8 to 12 years to fall to half their original brightness.

For an indoor wall, that is less worrying than it sounds. Indoor walls are set to run at 30 to 50% of their maximum, so there is headroom: when the picture starts to look a little flat in year four or five, the brightness setting can be raised to compensate. Outdoor walls have less in reserve, because they need close to full output at midday. That is one reason an outdoor specification should never be cut to the bone.

Three things set the pace: brightness, hours and heat. A wall run at full brightness, round the clock, in a hot recess ages fastest. The routine that slows it down is in LED video wall maintenance, simplified.

Colour drift, and why same-batch spares matter

The change you are more likely to notice first is unevenness. It has three causes.

• Uneven use. A corner that has shown a white logo for three years has worked harder than the rest of the wall, and has aged faster.
• Uneven ageing. Red, green and blue LEDs do not age at exactly the same rate, so whites can drift slightly warmer or cooler over the years.
• Replacement modules. A module from a different production batch starts life with a slightly different brightness and colour, and shows as a patch the moment it goes in.

This is why every PixelSpot wall ships with 5% spare modules from its own production batch. A same-batch spare starts out matched to its neighbours. There is one honest catch: a spare that has sat in a box for four years has not aged like the modules on the wall, so it may look a touch brighter when it goes in. Recalibration closes that gap.

Guard the spare box

• Keep it sealed, labelled and dry, not in a damp store room.
• Do not lend modules to another wall or another branch.
• Keep count, and tell us when it runs low, before it is empty.
• Never mix in modules bought elsewhere. A mixed batch also takes that part of the wall outside the warranty.

Recalibration: what it is and when you need it

Calibration measures brightness and colour across the cabinets, matches them, and sets the colour temperature for your room. It is done at commissioning, after module replacements, and after years of use. It is the right fix for a blotchy wall. Turning up the overall brightness is not, because it lifts the bright tiles along with the dull ones.

Run your own check twice a year. Play a full-white slide, then a mid-grey one, and look from where customers stand. If a tile or a whole cabinet looks warmer, cooler or dimmer than its neighbours, that is your signal. During the warranty, calibration after a covered repair costs nothing. After it, calibration is part of an AMC visit or a quoted job through our LED wall repair and AMC service.

What happens when the 2-year warranty ends?

Your pixel-to-pixel warranty lasts 2 years, counted from the commissioning date written on your handover report. Before that date, do two things:

• Send us a list of everything odd, however small. Covered faults reported before expiry are fixed at no charge.
• Count the spare box, and check it was topped up after every repair.

After that, there are three routes.

AMC is quoted for your wall's size. We also service and maintain walls we did not sell.

Repair or upgrade? How to decide

Faults in these years are usually single parts: a power supply, a receiving card, a module. Those are repairs, and quick ones. The frame and cabinets last 15 years and more, so replacing a whole wall because of isolated faults spends money on the wrong thing. Power supplies fail first, and the ones in a cheap wall fail sooner; the fire safety buyer's checklist explains what to look for behind the modules.

An upgrade does not mean starting again

Because cabinets and frame do not wear, an upgrade can often keep them: fitting new modules and receiving cards gets you a finer pitch for well below the cost of a whole new wall. For comparison, a whole new 10 × 6 ft indoor wall is about ₹4,37,500 + GST in P2.5 and about ₹5,91,500 + GST in P1.8, controller included. Before choosing a finer pitch, measure where people now stand and run it through the viewing distance calculator.

Where to go next

Five years in, a well-kept wall should still be doing the job you bought it for, with most of its life ahead of it. If you are earlier in the story, your LED video wall's first year covers what is normal and how claims run, and the LED video wall owner's manual covers install day and handover.
