Projector turns on but no light or image from lens.
The bulb looks good, the filiment is not broken. Projector is 4 years old and is used often. There is a blinking red light on the front of the projector and a blinking green light on the front of the processor.
Re: Projector turns on but no light or image from lens.
The bulbs do not always look broken when dead. You say it is used often. The life of a bulb is around 1400 hours I believe. This normally equates to a year or two depending on your usage levels. Did you notice your image getting dimmer in the months before it stopped working? This would be a good sign it was in need of replacement. Are the lights flashing very rapidly or blinking slowly? If they are flashing very rapidly this indicated the bulb will not fire and needs replacing.

It sounds like you have at least two bulbs out in the front. I suspect that both turn signals did not stop at the same time? Check the front bulbs. Many turn signal bulbs have two filiments; one for parking lights and the other for turn signals. The same filiment is used for turn signals and hazards.
Another possibility is that there is a bad or broken ground wire in the front?
Finally, it could be the turn signal switch.
try your emergency flashers, do they blink at a normal speed? if yes, replace flasher for turn signals.if not check the bulbs on the side that blinks fastest,even if they look good there could be a broken filiment.tap on the bulb, if the filiment moves it's a bad bulb.
if the status light is blinking red in 4 sec interval it means that there is something wrong with cooling system. you shold check if there is a thermostat failure or if there are any switches that are not turned on. i suggest you to open the device (using screwdriver) and check if there are any switches broken or damaged.
i had pretty much the same problem (one second interval). i took off the cover and there was a broken switch and i just short-circuit it and now it works
The projector should have a cable similar to the monitor cable that would normally be hooked into the computer. The cables work the same and the one coming from the projector will use the same port as the normal monitor cable. Make sure that there is a good connection on both ends -sometimes one or the other get moved and the connection is lost.
Once the cables are hooked up, the projector should be turned on. Normally the projector will soon begin a startup routine and will cause an image to be shown on the screen. You can focus the image during that time.
After the image goes away you should be able to display whatever you want from your computer's software.
Normal problems in doing this are: leaving the lens cap on the projector, having a burned out bulb - once the power is turned on for the projector, it should cause the bulb to come on. Some models have a power on switch and a display on switch that must both be pushed to make the bulb light up.
It isnt the lens. There is a crystal asembly that the light is reflected thru after it hits the color wheel. It is 4 pieces of completely mirrored glass glued into a small metal holder. One of those pieces has shifted. To fix it, you can take it out and possibly have a jeweler repair it. It is difficult to take out, but it is doable. Feel free to contact me if you need to. email is (bill @ baerwalde . com) Just remove the spaces.
This is NOT a bulb problem unless your "lamp" LED is lit, which you say it is not. Many people have reported this problem with the Optoma 72. You can send it in for warranty service (it has a 2-year warranty) to get the lamp controller chip replaced, but the problem may recur. Optoma does not appear to have a permanent solution to this problem. My projector has broken exactly like yours TWICE in a year. I haven't even needed to replace the original bulb yet. :(
