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

            Step 1: Check if power is received at the cabinet from which screen is blank. If it is connected with power loop & power is not received, check if it is has got burnt / damaged & change it using spare power loop cable if any.

            Step 2: If power is received at the cabinet from which screen is blank then check if power is received on the receiver card of that cabinet (Red light must be ON & stable).  If not, check the SMPS from which receiver card is receiving power is ON or not. If NO, then change that SMPS.

            Step 3: If power is fine & data is also received, change the hub card / receiver card.

            Step 4: (AS PER DATA PATH, IF CABINET IS AT THE END OF SCREEN, FOLLOW THIS STEP)

            After practicing above 3 steps if issue is still unresolved, check the continuity of data loop cable (cat6 from receiver card of working cabinet to receiver card of cabinet from which screen is blank). If found faulty, change it.
