Service / 02 Module replacement

Module replacement — the part, then the procedure

One module out.Five moves, one record.

Replacing a module is usually smaller than the anxiety around it: one part, in one position, held by screws or magnets. What makes it fail twice is the wrong batch, or the wrong hand on the connector.

01 / BATCH MATCHING

A repair is only invisibleif the batch matches.

Why we ask which run
your wall came from

Two LED modules side by side on black: pixel face on the left, driver board and hub port on the right
Two modules · same series, different runsVisible only against a flat field

Two cabinets from different runs do not look the same.

Same series, same pitch, same settings — and one cabinet sits a shade brighter than its neighbour. On a flat field, at night, it shows. It is the most common complaint after a repair that "worked".

  1. 01We record the batch at build — module, supply, card and firmware, against the wall's serial.
  2. 02We match from the record, not the shelf, and name the batch before anything ships.
  3. 03If the exact batch is gone, you hear it first. Accept the nearest, wait, or replace a run.

02 / THE SWAP

A module swap,in five moves.

What we talk your
technician through

01

Isolate

Power down that cabinet only. Note the position first.

02

Free the fixing

Screws or magnets — never force it.

03

Release the connector

Pull by the housing, never by the cable. Check the port for a bent pin.

04

Seat the replacement

Same position, evenly torqued — one corner first is how faces crack.

05

Prove it

Flat field at low grey, and look at the joint, not the picture.

Front or rear service decides how long this takes, not the module. Front-service is done from the viewing side; rear-service needs access behind. Which one you have is in your cabinet record.

03 / THE RECORD

Every repair closes with a record,not a thank-you.

Same family as
the diagnosis record

04 / THREE QUESTIONS

Asked beforea repair.

Straight answers
no conditions

Can my own technician really do this?

If they can use a screwdriver and follow a position plan, yes. What goes wrong is not the swap but the diagnosis — swapping the wrong module destroys the evidence.

What if the part is out of warranty?

Part number, batch and price in writing before anything is ordered. Nothing ships on the assumption you will accept it.

Do we have to send the failed part back?

No — but if you do, we take it apart and tell you why. That answer is usually worth more than the part.

Send the module serial.We confirm the batch before you fit one.

The diagnosis, the wall serial and a photo of the cabinet label are enough to quote.
