NovaStar: Blank cabinets of display; Receiver card failure
Potential Symptoms
- All cabinets are blank after a receiver card ( if no redundant signal)
- How to judge receiver card failure for J Series and L Series displays?
Environment
- Product: Nova MCTRL 660, MRV300Q, NovaStar brand sender box and receiver cards
- Components: NovaLCT-Mars
- Control System: Gold family or NPP Control using transmit common/open protocol, includes but not limited to DVN-4003, J Series, U Series, Q Series
Cause
1. If one RC card is fails, it will lead to all cabinets are blank after this RC( if no redundant signal).
You can use the NovaStar software (pictured above) to identify receiver cards not communicating the sending box/card. Send configuration parameters to each receiver card. If are not able to send the parameters to the receiver card, you will know that the receiver card is not communicating.
Resolution
- Make sure power is going to the card
- The cards in the cabinet should have a solid red light and a green flashing light.
- Check the cat 6 cable from the sending card to the receiver card. Swap this out for a new cable if necessary.
- Replace the receiver card with a new one and cycle power to the entire display.
- After replacing a receiver card, if the section is blank, try sending receiver card configuration to the specific receiver card instead of sending it to all.
- Reference "DD3242867, How to Configure a Sender Box " for instructions on how to load and send the receiver card configuration file. It may take some time for the new receiver card to read the config from the sending box. Switch the display to test pattern and then back to normal content to force it to take the new config data faster.
- If the recently replaced section still appears blank, or bright white, it might be because the new receiver card has not read the dimming values yet. Switch the display to test pattern and then back to normal content to force it to quickly read the correct dimming levels.
