Optoma E719 temp lite comes on in less than a minute

Dear David,

i have Optoma projector HD72I color wheel,
please patiently wait for some days, once i post it on Ebay, i will inform you at the first time.
lets keep in touch with freely,
best regards,
Jack

does the lamp come on during this minute period, or is it off. have you checked the air filter for good ventilation and air flow

Yes, if bulb was low price and was installed in old lamp casing then it is bulb that is not good and creating too much heat that exhaust fan can't throw out to make projector cool enough so temp sensor activates and send over heat signal to system control chip thus projector shuts down.
Please install original lamp that comes with casing to solve this issue.
If lamp was original then check exhaust fan that might be running slowly due to stiffness in bearing so temp sensor finds over temp in projector.
Hope these info will help you.
Thanks.

sounds like it's overheating. Clean out all the dust from it.

Remove the screws and check out the fan's working state.
EP759 have one big 92mm fan for the lamp, and three small, near 40mm, fan's for the optics.

Power of the bulb is very high, so just 1 broken fan can make that situation.

Possible cause is overheating.
Do you hear the fan working?
What happens when you use the lowest level light output?
Does it run longer?

Also possible cause is a faulty temp sensor.
AC wire connection may not be firmly pressed in socket.

AS regretable as this sounds component failiure was my first thought .. It's not the bulb temp sensor as the fan is opperating and that usually cuts all power .
You may find that as you have a bulb ( usually worth more than the units they reside in ) rather than a repair another unit of Ebay would be a safer and more economic conclusion ... Regards Vortash

I have a similar issue though mine isn't quite as extreme as yours. Got a couple things you can do.

1. clean out the projector with compressed air. You might have dust building up on components that is trapping heat.

2. Your fan might be burning out. Needs to be replaced. I'm still working on trying to figure out what tipe of fan it needs.

3. The temperature sensor might be going bad. This one is less likely and most complex to solve as it depends on how the system measures the temp. I haven't checked in detail yet.

4. Replace the whole unit or send it in for repair. Both options will be costly...

Go to the onscreen menu and check lamp settings. Disable auto shut-off.
