The calibration data is abnormal
•
Some LDMs are particularly bright when the screen is white, unlike others.
Inspection: Switch calibration off again, then switch to calibration on to confirm the existence of
calibration data.
You can also switch LDMs data and receiver card data to confirm that the calibration data exists and is
correct.
If none of the above is feasible, the corresponding calibration data needs to be reloaded and resend.
The whole screen doesn't light up
•
It may be caused by abnormal power supply and internal power board.
Inspection: Check to make sure the power supply and the power board are in order.
If the signal source is switched without a black screen, confirm that the input source is normal, the
signal line is normal, and the signal transfer board is working normally.
