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.

if it is a replacement lamp, was the lamp timer reset after replacement? if it's the original lamp and the projector only has 83 hours on it, there is either a bad lamp or a cooling problem.

That must be an overheating problem . If you are sure that you replaced the bulb correctly , then i would say that one of these parts [ Power transformer , or Fuse , or the whole Power PCB ] is hurt .

please rate !

WHY DOES MY HD OPTOMA DLP 70 TURN OFF AFTER FEW MINUTES?


If you have recently replaced the bulb you may need to reset the lamp counter in the projector menu.
If you have not replaced the bulb, the projector may be shutting down due to over-heating. Check that the projector is clear of as much dust and debris as possible.

I am betting that the ribbon cable to your color wheel has become loose. Here is a detailed slide show of a similar model so note where the cables are and check each one.

Bulb blows on gt700


Possibly a bad ballast or power supply going to it causing it to either kill the bulb or your old bulb may still be good. Did you rest the counter in the menu for the bulb life after replacing?

My projector will not power on. I've replaced the cables, the power source, and the bulb but still nothing. The red standby led on the control unit turns blue when power button is pressed but goes right...


The ballast unit has most likely failed. Replace the ballast unit, unless the lamp exploded and in which case, there may be glass fragments stopping a fan from turning.

I have an Optoma EP716 projector. It has run for


either the lamp has/is going to expire, or the ballast is bad. if the lamp has bulges or black spots on the inside, replace the lamp and clean out your projector with canned air. too much dust keeps in the heat and makes a 2000 hour lamp go in 1100 hours.

OPTOMA HD 70


You didn't include much information other than the lamp not coming on. Here are a few things to try, if you haven't already. Unplug the projector and allow it to sit for a minute or two. Try removing/re-installing the lamp assembly. Sometimes especially after a lamp change the bulb/contacts are not properly seated. Ensure the screws are securely fastened to keep the bulb seated. Are there any lights, i.e. power, bulb or fan errors lit? I've had my HD70 since 2006 and use it everyday for my main television. PS3, DVDs and Cable all run through it. I average one bulb per year and about 3100 hrs on each bulb. My last bulb actually lasted 3600. I have tried all the above and each has worked at some point. Hopefully you can have some success.
