Here are instructions for resetting the Lamp Hours for a Plus U2-1130

Purchase a Harmony 300 Universal Remote (I got mine at Target).

After you completed the normal setup steps for a Plus U2-1130, go into Buttons, and Change or Fix what a Button Does.

There are 5 programmable buttons on the Harmony 300 just below the device selector. Drag and Drop the following Commands from the right hand side into the programmable buttons (Power Off, Help, Enter, Power On). Keep track of where you drag them to. Sync the Remote. Disconnect and go to your Projector.

Click on Aux (assuming you assigned this button to your Plus U2-1130), to tell it you are instructing the Remote to talk to the Plus U2-1130. Now, Use the Power On (programmed button), Press Menu (standard button), use the Arrows (standard buttons) to get to the Power Menu. Press Enter (programmed button), use the arrows to get to the Lamp Hours. Now press and hold the Power On (programmed button) until the Lamp Hours reset.
