The lamp hours are getting up there but I switched to a lamp with less hours and still the same problem. Also I have thoroughly cleaned the vents thinking it may have been an overheating issue but the problem persists.
Any help should be appreciated, thanks.
The projector is designed
to do this once its counter reaches 2000 hours, until the run time counter is manually reset. It's a reminder to replace the bulb.
Read pages 44 and 45 in the projector's manual. Just changing the bulb doesn't reset the counter - that has to be done manually in a separate procedure.
From the bottom of page 45 of the manual:
Resetting the LAMP RUNTIME
If the lamp usage time has passed 2 000 hours (when LAMP POWER has been set to NORMAL), the projector will switch to standby mode after approximately 10 minutes of operation. The resetting procedure should thus be completed within 10 minutes.
1. Connect the power cord to the projector and a wall outlet, and switch the MAIN POWER on.
2. Switch the POWER button.
3. Press the MENU button to display the menu.
4. Press the up and down arrows to select OPTION and press ENTER.
5. Press the up and down arrows to select LAMP RUNTIME.
6. Press and hold the ENTER button for approximately 3 seconds.
7. The confirmation screen will be displayed and select OK.
8. Switch off the POWER button to reset the duration of the LAMP RUNTIME.
9. Confirm the duration of time in LAMP RUNTIME is reset to "0".
I've always run my projector in Eco mode (which not only lowers the power but correspondingly extends the point at which it begins to shut itself off to a higher number of hours than 2000) and in the High Altitude setting, which spins the fan faster to keep the bulb cooler. I've never noticed either a difference in brightness or any increased fan noise, and I sit with my head about four feet in front of and two feet below the projector. I have my projector right-side up on a wire-frame rack, and it's almost a foot from the wall behind it and from the ceiling, and it's many feet from the side walls, so it has lots of air circulation.
I just changed the bulb for the first time after 7 years of use, when it hit 3000 hours (I don't use it for daily TV viewing but just a few times a week to watch movies, concerts, or old TV shows). I changed the bulb purely as a matter of prudence, since there has been one person here whose bulb failed so catastrophically that it destroyed the socket it plugs into! (I mounted the projector right-side up because of all the reports here of the color filters sliding down out of position when the projector was mounted upside down - this place is an invaluable source of info from other users about what to do - and what to avoid doing!)
