You must reset the lamp timer after you replace the lamp before the unit will turn on. Do this:
Power on the unit. On the projector's keypad, hold down the the two volume keys simultaneously for 10 seconds. At that point the LED will turn green. Now you can turn on the unit again and it should work.

Red power, blinking red temp


Hi,

if the Lamp error and Temperature error lights are flashing red this means that there are two separate errors.

  • A flashing lamp light means the lamp failed to ignite. It could be a lamp driver problem or lamp failure. Replace the lamp to resolve the issue. If the issue is not resolved, then service the projector.
  • A flashing Temperature light signals a fan error. Turn the projector off and allow it to cool down. If the light is still flashing after the projector is turned back on, service the projector.
Goodluck..

After changing the bulb image will not come on and solid orange light appears


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

Projector wont turn on


reset the lamp hour counter by (after you plug it in) holding down the enter, down, and menu buttons then press the power button. if it comes on, replace the lamp, it's old. if not, make sure the lamp door is closed completely and there's nothing blocking the fans.

Won't power up


I had the same problem after I replaced my lamp. You need to hold down the:

On
Enter
Down Arrow
Right Arrow

simultaneously - this resets the lamp counter. After I did that my projector fired right back up.
