This is an unfortunate incidence and i will send you the serviceable manual of your projector if you can send me your contact email address to my email.Yes ,there are instruction to follow to replace lamps in projector if not you might miss it. First you must confirm that the lamp is OK from the vendors you purchase before anything.

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.

SOURCE: I have an Optoma H31
When the voltage goes to 250 vdc does the light light at all? Does the lamp itself, when removed, have continuity? If not, then the lamp may need replacing.
Or, the mode of the projector needs to be set so that multimedia inputs are accepted.
Good luck on this repair.
