We have replaced a faulty module but now the image on this module appears to be upside down

Some of the older premium indoor range of modules are designated as either “LEFT” or “RIGHT” and as such require that you check the spare module to be installed to ensure that it is the correct side module for the cabinet. The modules are denoted with L or R on their rear so you know which one to be using.

This affects indoor modules for the 2.6, 2.97 and 3.91 pixel indoor range
