Question about Optoma EP716 Multimedia Projector

1 Answer

Optima ep716 power light flashes green but cannot turn on projector?

Opened the unit and it appeared clean and dust free, no obvious loose connections. Bulb appears fine, no broken filament. Closed it back up, plugged it in, all it does is flash green on the power light on top, no fans kick in or anything else. Any ideas?

The green flashing light is jsut indicating it is in standby mode.

Just double check the connectors are in place and do not have any damaged pins. If the input is active from a laptop- make sure you have the external monitor enabled- some you have to manually enable, some you merely need to have the monitor plugged into it.

If all of that is okay and functioning, and it still will not get out of standby, open the unit and check the wiring to the DB15 connector for a broken wire, If those check out, visually inspect the power supply for any bulging electrolytic capacitors- if any are found, replace them with high ripple current types.

SOURCE: EP716 Optoma Projector Fuse

There is no fuse. I took my EP 716 apart to find out why it died. I found a resistor had blown on the power board made by the Tiwan co. Quazarpower.

either the lamp has/is going to expire, or the ballast is bad. if the lamp has bulges or black spots on the inside, replace the lamp and clean out your projector with canned air. too much dust keeps in the heat and makes a 2000 hour lamp go in 1100 hours.

Reduce the screen resolution of your computer monitor to 800 x 600 and check. Let us know the result.
Optoma is a SVGA projector. i.e. the maximum resolution supported by your projector is 800 x 600.

Benq w1000 project not turning on


Look at the manual page 34, for the indicator messages. I suspect it's the same problem I have (which I haven't had formally diagnosed yet!), which I believe is a defective fan. My projector had been making a really loud noise on startup, which varied in length and volume. Recently the projector has taken to turning itself off after being on for about a minute, and the power light flashes green, with the temp and lamp lights flashing red.

Optoma EP716 turns on but no picture displays


Don't ever just unplug the power cord while it is on. The bulb needs to cool down with the fan still on.
Did you ever connect a source?
