It sounds like your lamp may need replacing. Before you go that route try all of these:
-Make sure the lamp cover on the bottom is fully attached. -If you unplug the power cord while the fan is rotating, the lamp may not turn on about 1 minute when you plug the power cord next time. After the status indicator stops blinking press the power button to turn it back on. May have to press it multiple times. -If your Power Light continues to blink red/green then you should contact your dealer.
Sorry I couldn't be more helpful.

Hi,
Projectors are designed to be used with a lamp and will turn off when there isn't one present. You would have to purchase a new lamp to use the projector.

Projector was turned off wrong and now wont turn back on.


if the led flashes once in 2-second intervals and you don't hear a high-pitched whir, the colorwheel needs replacing. if you do, the ballast is bad. if it flashes 2 times, the lamp is past 3000 hours. 4 times, fan error. 5 times, temp too high and it needs to cool.

What does it mean when that blinking green light turns to orange one in lp 350?


Hi
This would be "Standby"
When you press standby, the display and audio turn off and a blank screen is displayed for 15 minutes.
You can change the amount of time the projector stays in standby mode; see “Standby Time” on page 27 for details.
The LED lights orange while the projector is in standby.
• If you press standby again within 15 minutes, the projector returns to normal operations immediately. The LED changes from orange to green.
• If you press standby again after 15 minutes, there is about a 60 second delay before the lamp turns back on. The LED flashes green while the lamp is re-lighting.
• If you don’t press standby again, the lamp turns off after 15 minutes. The LED lights orange while the projector is in standby.

In the manual there is a chart which will indicate the nature of the failure depending on the number of times the red led flashes before a pause.

Most common is the projector's lamp timer has exceeded the operational lamp time limit.

While the projector's red led is flashing, press the volume up and down buttons on the projector simultaneously and hold them both in for 10 seconds.
This will reset the lamp inhibit protocol.

However if the lamp has thousands of hours of use you need to replace it before it actually fails.
