## Keeping Your Projector in Top Shape

Home theater projectors require periodic maintenance to deliver the best picture quality. The two most important maintenance tasks are lamp replacement and filter cleaning.

### Signs Your Projector Lamp Needs Replacement

- The image is noticeably dimmer than when it was new
- Colors appear washed out or yellowish
- The projector displays a lamp warning indicator
- The projector shuts off unexpectedly (thermal protection due to an aging lamp)

### Lamp Life Expectations

Most Sony projectors installed by Smart Systems have lamp lives of **2,000 to 5,000 hours** depending on the model and usage mode. If you watch 3-4 hours per day, expect to replace the lamp every 2-3 years.

### Filter Cleaning

Dust buildup on the air filter reduces cooling efficiency and can shorten lamp life:
1. Check your projector's filter every 6 months
2. If visibly dusty, remove the filter and gently vacuum or blow it clean with compressed air
3. Replace the filter if it is damaged or cannot be cleaned

### What to Avoid

- **Never touch the projector lamp with bare hands** — oils from your skin can cause hot spots and premature failure
- **Do not block ventilation** — ensure adequate airflow around the projector
- **Do not ignore warning lights** — continuing to use a failing lamp can damage the projector

### Schedule a Lamp Replacement

Contact Smart Systems to order the correct replacement lamp for your model. We will install and calibrate it to ensure optimal picture quality.
