Dell 3400MP Projector - "temp" light blinking orange

Projector bulb went out and was replaced. Started it back up and it shut off after 15 minutes with the "TEMP" light blinking orange. According to the Dell manual, this is attributed to a defective fan. Fan was replaced. Now, it will turn on for a short period of time in which the bulb lights up and the fan spins, but the temp light still blinks and it will turn itself off after a minute or so. Any ideas?

If both lights are flashing orange, that means that the bulb needs to be replaced and the filter needs to be cleaned. Make sure you reset the counters for both after you replace them.

This is what your projector's user manual says about a flashing "TEMP" light :

"The cooling fan is not operating. Turn the power OFF and wait approximately 20 minutes. After the main unit has cooled down, please make confirmation that no foreign matter has become caught in the fan, etc. After performing any needed maintenance, turn the power ON again; if the same display is displayed, then please contact a sales store or a service company."

I had the same problem and fixed it today. The fan is 70 x 70 x 20mm. I could not find the exact one, but 70 x 70 x 15 works just fine and I was able to find that fan at a Micro Center store for $8.99. The fans should be blowing air out from the front of the machine, not blowing in on the lamp.

clean out the projector with canned air. dust keeps in the heat the projector is trying to expell. once it's blown out, check the fans to make sure they are spinning.

This is a very common problem with these projectors. The fans lock up and the units are out of warrenty. The fan you replace it with must be the exact same as the old one, even though it is the same as a 5$ computer fan. The processor will detect the non-dell fan and shutdown in the same way.I Havent been able to find any replacement fans that will work. I may be interested in buying your broken projector from you if you give up.

Email me at: nalexandrov251[A-T]gmail.com and we might be abe to work something out.

Lamp is burned out or makes a popping sound.
When the lamp reaches its end of life, it may burn out and may make a loud popping sound.
If this occurs, the projector does not turn back on. To replace the lamp, see on page 38.

WE have a projector that works for 15 or so minutes, then the lamp shuts off. Is that a warning sign that the lamp is failing and will soon need to be replaced?


Hi

Well you can turn on the option by browsing the menu option with system setup. And at the same time do give rest to the projector after continuous use. And do not waste lamp life. In some cases the GPU (Graphic Processing Unit) also malfunction. Hence check to make sure about this as well. And also make sure you have not set the time of shut off.

Dell 3400mp Projector is flickering


Hello. Based on the video, return the projector and get a new one since it is still under warranty. The symptom has nothing to do with the lamp or connections. It appears to be an image processing problem on the main board. The blank part isn't distorted or scrambled, it's MISSING!
