Lamp was changed (tried to 2 new lamps), but there is still no light coming out of the projector. No problem lights either. What could be the problem and how can i fix it. Should i open it and try to fix, where would i start if its optical problem?

There are several things that can cause this problem, but the first thing I would check is the filter. The projector requires airflow to keep it cool. If airflow is blocked, the projector will overheat and shut down automatically.
Other then POWER BUTTON light there are three lights more
1. lamp indicator
2. temperature indicator
3. computer input
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.
if TEMPERATURE indicator illuminating RED the projector still projecting and if flashing RED than turned of itself
Purchased our76C in Jan, 2007. It is our second unit now that has had the same symptoms. When the unit starts up, the Power light is steady green as normal for a few minutes, but no image is projected. After a few minutes the lights do as you described. Both times Epson support authorized a new unit to be shipped out immediately. They said they had no known issues about it and didn't indicate what was causing the problem. Apparently it is not just the lamp wither. Also, the lamps both had under 20 hours on them.
