Question about Canon LV-LP11 Projector Lamp for LV-7345, LV-7350, LV-735
Could be an overheat problem, check any fans and filters are not clogged with dust, lack of ventilation and cooling will trigger a safety shutdown
Posted on Sep 24, 2007
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. Insert the power cord plug into the wall outlet and then
press the MAIN POWER switch.
2. Press the POWER button so that a picture is projected onto
the screen.
3. Press the MENU button to display the menu screen, and
then press the F or G button to select the OPTION menu.
4. Press the ENTER button, and then press the F or G button
to select LAMP RUNTIME.
5. Press and hold the ENTER button for approximately
3 seconds. The confirmation screen, "LAMP RUNTIME
RESET." is displayed and select OK.
6. Turn off the power.
This will reset the cumulative usage time for the lamp
unit to zero.

I have a very similar problem. I already check the filter and cleaned it but it was not very dirty and it didn't help at all. Any other thoughts would be helpful.
same thing here. Temp inside the projector is normal, maybe its a failure of the overheat detector.
My projector turns on and the lamp comes on for about 12 seconds. Then the lamp shuts down. I cleaned the fans and filters. Still does the same thing. I opened the top cover and I saw a thermal sensor right by the lamp module. I believe it is the problem. I will replace it and if it works, I will make another post. Meanwhile, if someone has already tried this please let me know. Thanks.
