Vertical patch on screen / one row of module is blank OR one row of module is flickering

            Step 1: Check if main FRC cable (from hub card to module) of that row is loosen / disconnected. If No, then change that FRC cable.

            Step 2: If FRC cable is changed, still the issue is unresolved then check if 5V power is received at module by Digital Multimeter. If 5V is not received, change the 5V connector.

            Step 3: If the module on which main FRC is connected & it is working fine, check FRC loop (FRC from working module to module which is blank) and change it if required.

            Step 4: If power is received, FRC is replaced & still issue is unresolved, bypass that module & connect FRC to the next module. If it works, change the module which was blank initially.
