A user reports that their previously well-functioning LCD projector is no longer displaying an image onto the screen. The status lights on the projector indicate that there is no issue with power or overheating, but the lamp hours counter suggests the device is well beyond the manufacturer's recommended hours for bulb replacement. What is the BEST next step to resolve this issue?
Adjust the brightness and contrast settings from the projector's menu
Move the projector closer to the screen in case of insufficient light projection
Swap the video cables with known good ones
Replace the projector bulb with a new one according to the manufacturer's recommendations
