This Panasonic PT - DW10000U projector has a runtime of 19,223 hours. Each of its four lamps (Lamp 1 - 4) has 1149 hours of use. It doesn't come with a lens but includes the correct power supply. There's a known issue where the DVI - D input shows lines during light - dark transitions (check the last picture), and this problem doesn't occur with analog inputs. Also, the lens mount cover is missing.

Using this Panasonic projector is quite straightforward. First, make sure you connect it to the correct power supply included with the product. When choosing an input source, if you notice lines on the screen during light - dark transitions, try using an analog input as the DVI - D input has this known issue. As for maintenance, keep an eye on the lamp usage hours. Once they reach a high level, it might be time to replace the lamps. Also, since the lens mount cover is missing, be careful to prevent dust from getting inside the projector. When not in use, store it in a clean and dry place to ensure its longevity.
