Hi Steve,
Something else was having the same issue and it turned out the sensor of the lamp door was damaged. Check that the screws to hold the lamp door are still tight and that the door is snug when shut. A lamp cover that is loose won’t let the projector fully turn on. So try that first. The only other thing I can think of is that it might be your ballast wheel that has gone. How old is the projector?
Cheers,
Shelagh

Hi Ryan,
Interesting they both had the same issue with the door sensor being loose. Maybe this is a design flaw. Glad you were able to get both of them working. I will mention this solution to other people and add it to the list of things to check. Thanks for sharing this!
Cheers,

Hi Ryan,
Good detective work! Let me know what happens with the second projector.
Cheers,

Thanks for your reply Shelagh. I replaced the lamp with genuine epson lamp. But still it is not turning on.

It turned on once after few tries but after I unplugged it and plug it again it is not turning on but makes beep sound once.

So Ia have a conclusion to all of this. the short answer is both have been fixed and now run. The main issue seemed to be that the door sensor on both had broken in a way that was keeping it from actively reading when the lamp door was closed. (The plastic piece that the screw attached to broke off.) I super glued the fixture in both units. One worked right after I did that. With the other (which was the first one I messaged you about) I opened it up and kind of cleaned it out even though it didn’t really seem to be that dirty. I also detached and reattached all the wires inside. Though I’m not really sure what was wrong I also got this one working. My last reply was deleted so hopefully this one goes through if anyone in the future needs to resolve this problem.

Alright so here’s an update on this situation. It turns out both of them initially had the same problem which was a broken lamp door sensor. The second projector I mentioned is now up and running after opening it up and repairing the sensor (the plastic piece that the screw held onto had separated from the “roof” of the machine so I just super glued it back in place.) So that’s good I’ve got one up and running.

Now onto the first projector I mentioned. It also had a door sensor that had broken in roughly the same way so I did the same thing. Now it turns on (which is good) but all I see is a flickering mess. The image is very faint and it looks almost like a damaged vcr tape. Additionally I know it’s not the lamps as I’ve tested all three to make sure they work which they do. I do think you may be onto something with the damaged ballast or PSU though. Maybe it’s time to just let this one die but I’ll look into it a bit further. In any case I’m happy I got one working.

Hi Ryan,
For the old projector, if it is a damaged ballast then you can look into getting it repaired but sometimes to repair is more expensive than the replacement. If could also be the resistors and or the PSU part. For the second projector, I would start off checking the air filters are not blocked. Those red flashing lights in those series usually mean the projector is reading that the lamp is finished. How old is the lamp? It may have reached end of life or been bumped and is damaged. The fact that you are getting the screen and then it’s switching off points to the end of life signal being triggered. Once the projector gets that message, it won’t turn on to protect itself. If it’s the same model as the first one, you could try re-using the lamp as long as the first projector lamp is still relatively new. It’s a quick way to verify that you need a new projector lamp. It doesn’t sound like it’s another damaged ballast wheel though. Let me know how everything turns out.
Regards,
Shelagh

Hi Steve,
It’s either the filter being blocked so air can’t circulate and the projector overheated. Or it’s the lamp. Sometimes the lamp blows without the warning messages coming on particularly when if the projector was knocked or dropped. If anything has damaged the lamp, the projector won’t turn on. Open up the lamp area and check if there is any glass or if the lamp is damaged. You could also try replacing the lamp and see if that does the trick.

Shelagh

Hi, I have Epson Powerlite 965H projector. When i connected to the power supply i don’t see any lights on, even the power button, but it is making one beep sound. Do you still think it might be a lamp issue? I thought the power button will be on and the lamp button will turn to orange or red if it needs replacement.

Thank you in advance for your help.

Thanks for getting back to me. I feared that was the case which is unfortunate. We have not been able to get it to work since but it’s nice to have a good idea of what is actually wrong with it.

Now I’m dealing with another issue with a projector of the same model (optoma x600). This projector turns on and shows a blue screen briefly and then cuts off even though the fans are still spinning. Oddly enough the power light is also flashing in sets of 7. Maybe it is the same problem as the last projector?

In any case I’ll continue to do my own research into the issue but if you’ve seen this before or know what’s going on I would appreciate it. Thanks for your time.
