Other then POWER BUTTON light there are three lights more
1. lamp indicator
2. temperature indicator

witch one light is flashing RED or illuminated RED with POWER BUTTON orange light.
If LAMP INDICATOR light is illuminated RED than lamp runtime has reached 1800 hours. but projector still working.
If LAMP INDICATOR light flashing RED than lamp circuit failure, or abnormal function or lamp unit is damaged. In this case projector doing the same behave just like your projector.

2. Method2 : With using the remote control offered to consumer if you press the
menu button continuously, OSD menus will disappear then press the "9876" and

No one here knows where it is. However I found that if the lamp indicator is orange or blinking orange that means the life expectancy is nearing the end of its life cycle and you will get intermittant starts.
There is a problem with the lamp or around it? When it turns Orange, the lamp is at or near the end of it's life & needs replacing. What does the temperature indicator show? Orange, Red or Red Flashing? If not, then there is probably accumulated dust around lamp area
