no its just indicating that the lamp is reaching the end of its lifespan,

that means your lamp it is getting to the end of its life.
sometimes even if the lamp still good the TV will send you that message because that timer is closed to 5000 hours

What you can do is open the lamp door, closed again and the tv will ask you if you replaced it the lamp, and just say yes and that sign will go away

or just simple replace the lamp. 915P020010

if ure handy pop the back off and there should be a main power board and a fuse on it, make sure you use the same fuse if it is blown do not stick another type or size in it, put it back together and turn it on if it blows again it will be somthing else if not it should work

I just fixed the same problem and it needed 3 capacitors on the power supply circuit board. Two of them were 3300uF 10V. All 3 capacitors were bulged out on the top and measure defective. After replacing them the TV worked fine.
