JVC DLA-RS1U Projector turns off

I have a similar problem. JVC Project (DLA-RS1) shuts off after about 30 min to 1 hour of use. Everything turns off - bulb, fan, even the little light on the projector near the buttons. After 10-15 min the red light comes back on and you can start the projector.

I have seen this happen when I had installed a knock-off bulb. I believe the bulb runs a little hotter and the projector over heats. Now I am seeing it happen even with a JVC bulb.

I am in the process of taking the cover off the projector to see if anything is blocking the air flow (like a piece of broken bulb, which did break a while back). If a problem doesn't show up there I am going to check the fan to see if it is turning at full speed (maybe replace with a beefier fan?).

Does anyone have instruction on dis-assembly?

Dell 1209S Projector, tries to turn on, and the fan comes on for 30 seconds and then goes off again. It tries this several times and then the light bulb icon comes off and it doesn't do antything else

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.
LAMP light is solid amber If the LAMP light is solid amber, replace the lamp.
LAMP light is blinking amber If the LAMP light and the Power light are blinking amber, the lamp driver has failed and the projector will automatically shut down.
If the LAMP light is blinking amber and Power light is solid blue, the color wheel has
failed and the projector will automatically shut down.
Unplug the power cord after 3minutes then turn the display on again. If this problem
persists, contact Dell™.
TEMP light is solid amber The projector has overheated. The display automatically shuts down. Turn the display on again after the projector cools down. If the problem persists, contact Dell™.

My Sony VPLHS-20 has original bulb, now just shut off 50 mins into the SuperBowl. No fault light, in fact, no lights showing on the display at all. Bulb has around 1800 hours. I waited 10 minute, red...

Pretty sure it the bulb as most are rated at 2000 hours; but also check for full air flow - clean filters etc. Bulbs can run hotter as they age, so air flow is more important, because there is an inside heat sensor that will shut the machine down.

Keeps turning off

So, Shutting down to protect itself. The error light says it needs service, Cycling power makes it work for a few more minutes, then the Panasonic safety circuit shuts it down. Projector shuts down when bulb life gets to the danger zone, and also when its heat sensor says there is a problem.
So you have a bulb life issue or you have a dirty projector / fan cooling issue??

I say clean it up with some compressed air when it is cool, then check the # of hours the bulb has on it (in the menu).

Lastly brace yourself, the bulb is gonna hurt you :-$

Infocus LP130, Bulb fires then goes out

there is a problem with the power to the front fan from the main board. there are 3 wires going to the fans: one power, one return, and one signal. if the main board reads no signal from the fan's speed, it'll shut down. check the power going to the fans and the signal. you may need to replace the main board.

This is a DLP projection. may be that you have a defective color wheel motor or supply voltage to color wheel motor is out of range.

4805sp runs 4 or 5 minutes then shuts down

Hi there

Yeah, thats the bad fault that one. The fault you have described is the main controller board giving up the ghost and stops supplying enough voltage to the fan tp allow it to run, and shutting down after 4 or 5 mins is the safety thermostat on the bulb cutting it out as to not cause any damage due to overheating. My projector had both these same faults, I ended up just buying a new light tunnel after many attempts of glueing mine back together unsuccesfully =(, and to fix the fan issue (without spending $800 on a new controller board), I permanently mounted the insides of an old nokia charger inside the projector, which supplies the fan with its own power source, worked like a charm =D. Yes I would be more then happy to send you the service manual, may I have your email adress to send it to?

Panasonic AE900U Projector

Check the manual if you have it or on line. The symptom you are describing may be a built in warning that your bulb has reache 2700 hours. I think there is a reset process and then at 3000 it goes out. Spent today reading the manual because I have one and the red lamp light is blinking. I called Panasonic and found out the only place that services these units is in Leawood Kansas USA> The place is called Heartland Services.
