You need to reset the lamp timer, usually done by holding some buttons while turning on

Optoma ep 1690, the on/standby led is flashing green but when I try to turn it on the temp and lamp led's flash twice and nothing happens, the on/standby continues to flash green.


The projector lamp life may have exceeded its safe limit, check your instruction manual, sometimes you have to hold the on or off button for 10 seconds to reset this. All manufacturers are different but that may be the problem.

Here is a copy of the manual, I havn't read it, my solution is from experience of other projectors.

The problem with my projector is it keeps flashing green and red


hi,

your statement is not very specific but if the power led is flashing green and the lamp led is flashing red that indicates a fan failure.

contact optoma support here and enquire if you can have a warranty repair, or how much it may cost to have the fault fixed.

My projector will not power on. I've replaced the cables, the power source, and the bulb but still nothing. The red standby led on the control unit turns blue when power button is pressed but goes right...


The ballast unit has most likely failed. Replace the ballast unit, unless the lamp exploded and in which case, there may be glass fragments stopping a fan from turning.

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.

Only power light will power on for few seconds then flashes.


Does the main lamp light at all? It sounds light a cooling fan failure. If the fan iis not working the the main lamp will not turn on and the power light will flash.

Projector will not project light (Mitsubishi LVP-X80U) LCD Proje.


Hello toma_leonard,

First check your lamp to make sure it is seated properly in the socket.
Then check all of your interlocks (see your manual for locations), these are usually located on any hatches or doors that allow access to the lamp and or fan area. Once you check your interlocks make sure the filter and fan area is clear of dust, (some projectors have air flow sensors), and the recheck the interlocks. Once this is done , If the interlocks are not broken, or the lamp fuse blown, the projector should be working. If not it is the lamp that needs changing.

I know this may be expensive, however these lamps do go bad, as much as we wish they would not.

If you still feel it is not the lamp, have a technician check the voltage levels to the lamp and the levels of the control board circuitry.

I hope this helps,

Thank you,
