Optoma GT 1080 Darbee projector is not working

Today it happened what I never thought might happen: my projector refused to turn on. I bought it two years ago.

Even worst: the red led turned off and it's not responding to anything I did.

AC cable is fine, as I checked power coming through it with a multimeter. I also tried another AC cable and another AC wall socket. Nothing.

My suspicions are the worst possible: that the power supply stopped working.

I can't find any fuse socket to see if there's a fuse that might have blown. Does anyone know if there may be a fuse anywhere and how I get to it?

The problem is serious, because I do not live in the USA. I live in Brazil, so I don't have access to projector repair facility of any kind. Even less for Optoma.

It will be unlikely that I find someone that would look into this or repair it.

So the first question is: is there a way I can get a Service Manual for this projector? Where?

Second, is there a place where I can get a replacement board, if the problem is in the power supply and needs to be replaced?

If the fuse blew in the power supply it is most likely soldiered in and blew because a component failed and just replacing it won't fix anything. I can't help with a Manuel but anyone qualified in electronic repair should be able to repair it. Check eBay for a PS as one used or new maybe available. Of course if a component shorted out on the main board it could also blow the fuse.

It's most likely you are right about an eventual blown fuse being the result of a failure somewhere else.



Unfortunately things are not so easy in my country to find someone qualified in electronic repair that will want to solve my problem.



I have already contacted Optoma's Parts department to see if I can get a manual.

Don't count on Optoma to provide an end user with a ton of support beyond telling you where service shops are.

Check FixItFrank on YouTube. He does a complete breakdown of a HD20 from Optoma with a power supply replacement. Maybe not at all the same, but will get you a good idea of the level of effort which may be required here.
