4-1-12 Network Error
Cable connection
between Set & LAN ok?
Check Network connection
Test in the setup menu?
Change the MAIN PCB.
 The connection between LAN and SET is direct. So there is no need to check H/W if there is network problem.
If it is, the problem is MAIN CHIP(IC1)'s BGA soldering problem.
It must be changed to new board.
