Your Sharp projector's image has gone soft, the zoom won't hold, or the lens has simply worn out after years of daily use. The XP50ZL motorised short zoom lens is the direct fix. Drop it in and your XPA824UW/B, XPA104UW/B, XPV731UW/B, or XPV801UW/B is back to sharp. If you've seen this listed as NP50ZL on a Sharp service sheet, it's the same lens — different part number, same glass. Not sure it's the right fit for your unit? Call us with your projector model and serial. We'll confirm before you spend a cent
