PB6110 Powers down after 30s, splash screen appears, red temp lig
PB6110 starts booting, (fan goes on flashing power light) then splash screen appears, (lamp has only 184 hours) and then displays input (I'm running a DVD) player, then the red tempurature light goes (while the lamp remains green) and then the whole thing shuts doewn (power led is yellow) fan shuts off.
What gives? Is it a faulty temperature sensor... BENQ was less than helpful..

Is the fan that cools the projection high intensity bulb running? This sounds like an overheating condition, there is a temp sensor that will shut the machine down if it senses the temp is to high and poses a fire hazard or further damage to the projector.
if the Lamp error and Temperature error lights are flashing red this means that there are two separate errors.
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.
Projectors shut off when they overheat. They overheat when air does not move through the projector cooling it. This happens when the fans are not working or air filters/vents are not working.
Check to see whether the fans are working. If they are working, open the cover and see whether air filters/vents are covered with dust. If so clean them.
I have an epson 9000i that did the same thing. Turns out that unit has a small fan (I think 60mm) right next to the power supply to keep it cool, in addition to the large fan that exhausts past the lamp. The fan runs non-stop as long as the unit is powered-up for two reasons I can think of - keep the power supply a little cooler, and the lamp a little warmer so there's not such a temp difference when it powers-up. Long story short, that fan had died. I replaced it with an aftermarket 60mm fan and it's been working fine ever since. Hope this helps.
This would appear to be a bulb that has reached end of life -- or the projector thinks that it is because of hours. Usually most bulbs are 1000 or 2000 hours. Depending on your projector there are different ways of checking bulb life hours -- if you Google your projector model number and "bulb life" you will usually get a post on how to check these hours. Also, if it is a new bulb and you haven't reset the hours counter, it may need to be reset (however you also don't want to wait too long before changing a bulb that has reached EOL since they can and do explode sometimes taking out the projector with it).
