Hey Yosh, yes you do have to reset the lamp timer following a lamp change or replacement. Follow the steps here to carry out the timer reset.
- After the start-up logo, press Menu/Exit and then press / SYSTEM SETUP: Advanced menu.
- Press to highlight Lamp Settings and press Mode/Enter. The Lamp Settings page displays.
- Press to highlight Reset Lamp Timer and press Mode/Enter. A warning message displays asking if you want to reset the lamp timer. Highlight Reset and press Mode/Enter. The lamp time will be reset to "0".
Warning: Do not reset if the lamp is not new or replaced as this could cause damage.
