It sounds like the lamp is going.
Do you know how many hours of use are reported on the lamp?

Many times these projectors have circuitry to shutdown when they suspect the lamp is near the end of life. Lamp hours vary and usually will go up to and even beyond expectancy, but there is occasions you can receive a bad lamp and have it blow in a matter of hours...not common but it does occur.

I hope this helps,

I have a model and swapped the T45U projector lamp, the projector turns on, but in a few seconds it shuts off, and turns on the LED "Temp" what can this be?


hi,
First of all check the lamp hour . Reset the lamp hour and try again. It is recommended that reset lamp hour only after replacing the lamp. No matter, just reset the lamp hour. If problem doen't repeat the try to replace lamp.
Another possible problem is the faulty lamp cooling fan. Check the lamp cooling fan of your projector. maybe its has some problem.Do one thing, Remove the fan from the projector. In the fan there will be a specification sticker. Remove the sicker. now u can see a hole in the center. its the bearing part of the fan. put one drop of oil in it. u can use any type of lubricating oil. rotate the fan leafs with finger for some time. after that re-stick the spec sticker. insert the fan in the projector.
ok

I'm the original owner of this projector with not many hours on the lamp. About 1 year ago it became difficult to turn the projector on. Eventually I would get it turned on by multiple attempts and...


Hi Ron.

Re:"a clicking sound that continues for 20-30 seconds than stops as the projector "gives up" trying to turn on"

The clicking sound and the projector not responding is not indication of a particulare issue or fault, but just the generic protect mode that kicks in whenever a fault is detected.
The condition is called protect mode or protection.
The clickin noise is a safety switch that keeps turning off the unit until the projector shuts down completely.

When the problem is the lamp the unit does not go into protect mode, but usually there is a well defined diagnostic condition (eg. a lamp light on). I do not think that the problem is the lamp.
Most common failure is the PSU (power supply), with in second place convergence issue. Other faults, like the lamp power board or main digital board failure are still possible.

As first trubleshooting, try leaving the projector off and disconnected for one hour, that will probably not help, but is a necessary step to ensure that there is a fault.

If that doesn't work, then the choice is between calling manufacturer and taking the projector to a local technician.

My Benq PB6100 shut off after a few seconds


I had the same problem.
First thing to do is look up the owners manual, unless you happen to still have it, then verify the the sensor for the second (or rear something that sounds not like first) temp sensor is going off. If it is basically the fan that sends air into the lamps compartment may be clogged. I have had mine for several years and recently had the same problem. I almost went out to buy something new until I convinced myself that there was no harm in taking it apart and trying something. Good thing too, since all I had to do was clean the fan and reassemble. After that it stopped turning off by itself and I haven't seen any red lights.
Good luck to You!

The projector switching off after 30 seconds


check the following :
1.does the lamp glow
2.do u get the connected image
3.if yes does the screen show temperature or overheat
4.if yes then one of the cooling fans do not work properly & hence the unit turns to standby & goes into protection
if no 1 does not happen, then check the lamp physically,it should not show melted or breakage.
if the lamp seems ok, then the ballast is defective!
