Einleitung

A replacement of the power supply unit is needed if the projector shows no sign of power despite the use of a functional power cable. It is located within the Epson Home Cinema 2150 almost at middle right next to the projector lens. It's a heavy black box.

The power supply is designed to deliver the proper power to the projector.

Remove two 9 mm Phillips #2 screws.

Using four fingers, pull upwards on the lamp's plastic casing.

We noticed these steps are exactly like the first 3-4 steps of your other guides. We would recommend you to make this a prerequisite guide for those 3-4 steps (mostly unscrewing to open the device up) and then reference them before starting the other replacement guides.
