Hi to all.
this tv works fine about 5-10min and than no screen no backlight stby led is staying blue on(not red).
by cheaking the power supply (including inverter)stby 5v is ok.
sometimes when the problem is apear volttage frome p.s 16v and 12v are ok and somtimes not and the inv pin and power pin is 0v.
thinking about main board problem(LP81A EAX40043810(3).

 hi,
never had this problem but i think the inverter fails to work;try to find out what ic is mounted and try to disable the protections.
