Wow I may have just fixed the flashy yellow status light problem. It's so siple yet so difficult. Looking at the front of your T.V. on the left hand side bottm there is a door for a filter. SMACK IT. if the door isn't shut all the way that status light will flash. Mine is turning on now, just have to work on the major problem now :) Hope you have the same simple problem.

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

Check that the lamp door is closed all the way. There is a saftey switch that closes from the door being on all the way. If not the status light will keep blinking. There is also a switch on the air filter door.
