Thank you for responding to my post. I just realized I must have posted twice by mistake, and you read the shorter message. I copied my second post below which has more details. Thank you in advance for your advice and suggestions. I have owned my sharp xr-10x for 2 1/2 years now, and for the most part, it has worked well. My current remaining lamp life is 76%. However, recently the projector lamp dims, then turns off at irregular intervals (10 mins-over an hr). The fan remains on and, after a couple of minutes, the lamp turns on again. The standby/on light remains on through this, and the lamp light blinks green while warming up again. I am afraid my lamp life has diminished due to the frequent shut-off and back on periods. Any suggestions?

Unplug the power cord from projector
--> HOLD down (keep holding down) the right key on the keypad (top of the projector) and Insert the power cord back to the projector
--> The "Power" and "Ready" LED light should blink TWICE and unplug the cord from the projector (while still holding down the right key)

If your projector won't fire up then you can't reset the lamp counter so that is not the problem.
The combination of LEDs you have given does not correspond to an error message. There should be two LEDs, one of which is the Lamp Indicator, and the other is the Temp Indicator.
It's possible that an overheating problem has caused this. Make sure the projector is in an area where the temprature is between 0 °C (32 °F) and 40 °C (104 °F) and the humidity is between 20% and 80% (with no condensation). It shopuld have unobstructed air flow around it.
Disconnect the power. Remove the lamp and place it aside. Clean the air filters, using a hoover, being careful not to damage the filter which is located on the underside at the front of the projector under a flap.
Carefully reinstall the lamp (when you say you replaced the lamp, did you buy a new PANASONIC lamp from a reputable source?) Try to fire up the projector. Note down any combination of LEDs if the projector doesn't work and post hem back here.
I just got done talking with Dell, they told me to unplug everything from the projector, power source and all. Then Press and hold the power button down for 45 seconds. This will disapate the electricity from the capacitors. Plug everything back in, and test. Seem to wook for me!! Good Luck
usually the projector powers and cools down. if you restart it it will open the cover, not projecting anything and after 10 seconds it will close again. this happens if the lamp is shortly before the end of the measured lifetime (no fixed hours) to protect the projector. usually if you take it out once or twice it will work for 1 or 2 more times but the bulb is very likely to explode (not destroying the projector but not good anyways)
If your bulb finally reaches it's end before you have the chance to replace it you unit will shut itself down and go into a permanent standby mode. Changing the bulb alone will not remedy the issue. The solution is quite simple but not posted in the manual or anywhere else that I could find for that matter! All that is required is to hold down the HELP button on your remote for 10 seconds while aiming at the infrared sensor on the unit. This will reset the units bulb timer and remove it from the standby mode.
I think this projector uses a color wheel. It's literally a wheel a transparent wheel divided into different pie shaped colored sections.
I am not an expert (or even close) on these proejctors, but I would guess that a fall like this would cause a mechanical problem and the wheel is a mechanical part. If it's not allowed to rotate properly it could be the problem.
If you're in a brave mood you might open it up and see if the wheel is able to spin freely.
