screen, Rebuild the cabinets
Control System & Image Rendering
Purpose of the Test:
- Once the screen is installed according to the normal cabinet
configuration, we make sure we can normally control it.
Parameters to check:
- rcg/.con files
- quality of the image/video
Solution in case of failure: Modify rcg/.con file
Brightness, Calibration and Uniformity Checking
Purpose of the Test:
- We will check the maximum brightness your screen can
give, and evaluate its eveness in RGB and White. We also make sure
the masks are dark and uniform.
Parameters to check:
- RGB & White eveness
- Brightness
- quality of the mask
Solution in case of failure: Re/calibrate the
screen, change the masks, rescrew the masks
On-site Full White (255) Testing
Purpose of the Test:
- We will do an aging test, at full white. This is to see the
performance of the screen in term of image and heat dissipation.
Parameters to check:
- reliability of the soldering
- continuity of the Brightness/colours

- is the cabinet still working after testing
Solution in case of failure: Re-screw the
components
LED Specifications Checking
Purpose of the Test:
- We will pick up LED from the spare parts and check their specs.
Parameters to check:
- wave length
- Colour temperature
- Diffusion angle
Solution in case of failure: Change modules
Spare part Listing
Purpose of the Test:
- We check list your spare parts in order to be sure that
you will have all what you ordered.
Parameters to check:
- full spare part list
