Why won't my Plus U3-880 Projector power on?

  There are several reasons why your Plus Projector might not be turning on. First, ensure the power plug is securely connected to the power outlet and that the lamp cover is correctly installed. The projector has a protective feature that prevents it from turning on if the internal temperature is too high. Also, the power will not turn on when the lamp usage time has exceeded 1100 hours. Finally, high-tension noise to the power line with extremely high pulse can stop the projector; if this happens, unplug the power cord from the outlet and plug it in again.

  If your Plus Projector remote control isn't working, first check if the send indicator (LED) lights up when you press a button. If it doesn't, replace the batteries with fresh ones. Also, make sure there are no obstacles between the remote control and the photoreceptor on the main unit. Ensure the remote control is being used within its effective range and that there isn't a fluorescent light or other strong light source close to the photoreceptor.

  If your Plus Projector images are blurred, start by ensuring the lens is properly focused. Check that the screen and projector are positioned at the correct angle and that the projection distance places the screen within the focus range. Also, inspect the lens for any condensation, dirt, or other obstructions. If condensation is present on the internal optical system because the projector has been stored in a cool place and then used in a warm place, wait several minutes for it to evaporate.
