Optoma EP719 Power Trouble

The lamp will not even try to power I have put the meter on the terminals and not even 1 volt. I have switched the bulb also. Does anyone have any idea or even a service manual would be great.

When I plug it in the power light flashes then when I push the power the power light goes solid and after a few seconds the lamp light comes on solid for 1 sec then the unit restarts. I can hear the fan running. Does anyone know what the problem might be?

Thanks

There is an online disassembly guide but it sounds like the lamp out to me.

Gets you part of the way. It's basically a bunch of screws. It's pretty simple to take apart. I've done it a few times myself for cleaning.

I have torn down the uint and swited out the lamp with a different lamp. It still acted the same. I have put a metere on the termins for the lamp and bypassed the switch. When I try to power it on the meter never shows anything on the screen. So I thinks it is someware in the psu. But without a service manual or schematics I thinks I am lost.

If the fan come on I'd not expect it to be the psu. I suspect something is going on with the lamps.

Do you happen to live close to fort worth TX?

No I live in Ohio. I do have electric expericence. If there is anything you can think of for me to test I can do it. I have looked over the boards and there is no damaged components that I can see or smell.

Thanks
