Why does my Mitsubishi UL7400U display 'TEMPERATURE!!'?
- A
  Angelica FosterSep 4, 2025
  The 'TEMPERATURE!!' indication on your Mitsubishi Projector appears when the ambient temperature rises too high, potentially causing the lamp to go out. It can also appear when the air inlet or outlet grille is blocked, which will also cause the lamp to go out. Try these steps: * Eliminate any causes of the rise in ambient temperature. * Remove any objects blocking the air inlet or outlet grille.

  If the projected images from your Mitsubishi Projector are wavy, consider the following: * Securely connect the plugs of the cables to external devices. * Keep the projector away from devices that emit interfering radio waves. * If the keystone adjustment is carried out, the image may not be displayed correctly depending on the type of input signal.
