- We have replaced a faulty module but now the image on this module appears to be upside down
- How do I know if the screen is receiving data or not?
- I cannot get the screen to power on
- The screen keeps dropping in and out, after turning it off and on at the power source, it comes back
- When we look over the front of the screen it is not uniform
- I can see bright green, red or pink pixels that should not be there
- I have turned the screen on and I am seeing a white snow-like image
- I have ordered and replaced a LED module for our screen and it is seems to have a different brightness and colour
- I can see a row of LED’s that are a strange colour or slightly different to the rest of the LED's on that module
- The display has strange blotching, jittering or resolution problems
- When we turned on the display after installation, parts of the screen are in the wrong position
- I cannot locate the USB for the LED screen we purchased
- Half the screen has gone black
- The Display seems to be flickering
