Replaced the old bulb with a brand new bulb. Hung the projector up and plugged it into the wall and POP. A popping sound came from the projector and popped my GFI. I tried to install my old bulb and plugged it in and the no pop this time and the GFI stayed on however when I push the power button the fans come on but no light from the bulb...I can hear something spinning and sounds like it will start up but nothing and it shuts down after a minute or so.

Sounds like something in the power supply blew. Transistor or diode most likely.

Light went out; ordered new bulb; replaced it. Now unit won't stay on nor will lamp light. What to do?


It sounds like the ballast (the high voltage source that powers the bulb) may have failed. Unless you are exceptionally good with electronics, this is likely not a repair you should attempt on your own. I would recommend contacting Optoma's tech support for more information:

Optoma EP719 projector broken circular glass disk


The piece that's cracked is called a color wheel. I spoke with the parts department at optoma and they want $300 for a new color wheel for my ep 732h projector. I'm not sure if it's the same part but you can contact optoma on their website and they'll get back to you with a price quote for that part.

I have the Optoma ep719 and it will not power on. I plug it in the power light flashes. When you hit the power, the fans will come on and the bulb will light up for about 2 sec. Then it will go back to the...


some dry out, and you can't tell by looking at them. see if the colorwheel is spinning. if it chirps before it shuts down, or if it doesn't spin at all, replace it. otherwise replace the ballast.

Optoma EP719 Projector Won't Power Back On


When you first replaced the bulb it went back on and then later it did not. Most projectors have a safety switch that it is activated upon the bulbs cover placed. Once the cover is removed it activates the switch and shuts down power to bulb. It sounds based on your remarks, that this switch may have intermitten problems. I would suggest, locate this switch and verify its operation. Or, make sure the bulb cover is placed and/or secured properly.

Try this: There is a stuffed 10v 3300uf capacitor on the power board. You need to replace it.
Bellow you can check in the picture where the capacitor is located.

Notice that in this picture I have already took the bad capacitor out and replaced with two small cords to reach the bottom and test the new capacitor.
To reach this place is not fast, several layers of plastic and metal must be removed, but is not a hard task to take the capacitor out and replace it for another.
It works just great! Now it is back on track with awesome image.
