How to fix an Epson PowerLite S4 when the power indicator light is red and it's overheating?

If the power indicator light on your Epson Projector is red due to a high temperature error (overheating), the lamp will turn off automatically. Wait about 5 minutes for the projector to switch to standby mode. Then, ensure the air filter and air exhaust vent are clear and that the projector is not against a wall. If the air filters are blocked, clean or replace them. Press the power button to turn the power back on. If the issue persists, stop using the projector.
