Big patch on display / one cabinet is blank OR one cabinet is flickering


Possible Causes
Steps of Solution
1. SMPS is Faulty
1. If power is received at the cabinet(s) where Main Power is connected, check if the SMPS through which power is provided to Receiver Card is giving an output of 5V-DC. If NO, Change the same.
2. 5V Connector is Faulty
1. If the SMPS mentioned in Scenario-1 is working, check if 5V is obtained at the Receiver Card. If not, change the 5V Connector (Cable connected for power from SMPS to Receiver Card).
3. Loop Data Cable is loose OR Faulty
1. Check the Data Loop Cable (which is connected from cabinet to cabinet) by bypassing it to the next Cabinet/Receiver Card. If it doesn't work, replace the same.
4. Receiver Card is Faulty
 (If there is only 1 Main Data Cable)
1. If all power & data concerns are working fine, check the Receiver Card (in which Main Data is connected) by bypassing it to the 2nd Cabinet/Receiver Card. If it works, replace the 1st Receiver Card and re-program the same.
