Ensure You can find ample airflow around the projector notably if it’s been permanently mounted. I do like my Microvision ShowWX+ pico laser projector for it’s surprisingly clear picture (under no circumstances must concentrate) but it does lack a lumen or two… Remove the lamp and cleanse the area within. https://epsonprojectorbulbproblem55565.targetblogs.com/37158220/getting-my-change-light-bulb-epson-projector-to-work
