Optoma HD66 replaced lamp, LAMP WARNING light keeps flashing, still won't turn on?

I turn my projector on and the power light goes solid green. Then after a few green light blinks the LAMP WARNING light turns red and the power light flashes orange. I bought my lamp from best buy and the lamp says on it that it's legit. HELP!

SOURCE: Optoma 719, can't get lamp and fan to turn on.

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.

Optoma HD80 flashing blue lights


Sound like the original color wheel for Optoma HD80 is bad.

If the unit has been moved when hot.

If not, try un-plugging the unit for a few minutes and re-connect.

Hope this helps

Check the voltage at the lamp input from the ballast after connecting projector to mains supply. (Warning: Do not switch on the projector while checking the voltage. It will damage your multimeter) The lamp connection shall be removed. If the voltage is around 60 to 80 volts AC, then your ballast is OK. Check for fragments inside the lamp.
