Scratches and dust accumulation can significantly impact the image quality of the lens. Even if the lens may not be fragile, the coting of its surface is delicate and prone to damage. It is an important part of the projector as it is able to magnify images and display them onto a surface. If the image is distorted in any way, it may be caused by a dirty or faulty lens. It is necessary to replace the lens if it is cracked or otherwise damaged. Caution should be applied when handling the lens front element, as glass is fragile and easily cracked.
Before beginning the repair be sure the projector is unplugged from the outlet. Also make sure that the projector has cooled off if it has recently been used as it could become warm after prolonged use.
