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.

Why does it work for 10 min, then turns off?


U might have a thermal issue or better still, a false overheating signal being generated. If you have one of those small 8 inch desk fans, put it on full blast and give the unit the mother of all blow jobs while turned on to see if it shuts off. If it still shuts off something else is wrong. If it continues to work then ........................

My vivatek h1080fd after running for a while starts to flicker, loose resolution then shuts down


I have temporarily fixed this issue by directing a fan at the intake vent on the side of the projector. it's gotta be the intake vent and not the exhaust.

Turns on and runs for 2minutes and shuts off


Hi, Did you buy it new? How many hours does it have on it. I have a Sharp projector for which I bought a used bulb which started for 1 - 2 mins then shut off. Restarted a minute later then shut off again. I bought a new bulb and that solved the problem. It could also be a weak ballast if the bulb has low hours or if the filters are dirty, it could overheat and shut off. Make sure the filters are clean and the cooling fans are running and the unit has good ventilation.

Hope this helps,

NP310 NEC Projector shuts down after about 15 min.


Check for good air flow: that filters are clean and the fans are running and not blocked. Check the bulb hours - it may be nearing the end of its life expectancy. If heat is the problem, the inside temperature sensor will shut down the machine or it may be faulty. Inside electronics would be the next suspect.

Projector keeps turning off every 5 mins


if just the lamp turns off and the rest of the projector is running, it's time to change the lamp. if the whole projector turns off (not goes through shut down), it may be a power supply problem.

I turn tv on...green light comes on but i get no picture or audio....then light indicator blinks red


Hello!
Lamp or ballast(if lamp has been replaced) is bad.
Explanation: green comes on: system works, waiting for light to shine into light engine: no light is coming out of lamp, system shuts down, then you see red! how to determine: pull the lamp out of the unit's compartment. Inspect lamp: bloated stem? shuttered? reflector is not shiny? Chuck it!
Lamp looks good or just been replaced: try ballast. Close lamp compartment without lamp itself. Make sure, door is shut, as well. Turn unit on and listen close to lamp compartment: good ballast will make a buzzing noise, then stop. You've got "red'! No buzzing: ballast quit. Needs major repair! Lamp must be good, for sure, to get to the last part of diagnostics. Conclusion: more, than 2000 hours of usage: replace lamp first!
Good luck,
Alex.

Infocus LP 280 runs for 1 min then shuts down, runs again then


are the leds on the top lit or blinking? it could be the lamp, the ballast, or the fans. check the lamp. if there are black spots or bulges in the lamp, replace it. if not, make sure the fans are running. if they are, replace the ballast.

I have the same issue, I have figured out its a fan issue, my fan must have went out. After about ten minutes the bulb will get too hot and the picture will start to turn a way off tint color. I put a fan on my projector and after about 40 min. the picture returned to the appropriate color. I am still investigation on how to get and replace the fan.

HD72I WORKS FOR 30SECONDS AND THEN SWITCHES OFF


I had the same problem with very few hours on the lamp. Sent it back to the factory and they said the fan was overheating causing the bulb to shut down. They replaced the fan and the bulb for free under warranty. I noticed before I sent it the projector was putting out an incredible amount of heat. MUCH better after fan replacement.
