Disconnect the LAN cable and check that the 
projector is working properly.
If this phenomenon occurs after connecting to the 
network, there may be a loop between two Ethernet 
switching hubs within the network, as explained below.
-   There are two or more Ethernet switching hubs in a 
network.
- Two of the hubs are doubly connected by LAN cables.
-    This double connection forms a loop between the two 
hubs.
Such a loop may have an adverse effect on the projector 
as well as the other network devices.
Check the network connection and remove the loop by 
disconnecting the LAN cables such that there is only one 
connecting cable between two hubs.
