What to do if Epson EH-TW420 Projector indicator light is red?
- M
  Monica Collins DVMSep 1, 2025
  If the power indicator light on your Epson projector is red, it could indicate several issues. If the issue is High Temp Error (overheating), the lamp will turn off automatically and projection will stop. Wait about five minutes for the projector to switch to standby. Ensure the air filter and exhaust vent are clear, and the projector isn't against a wall. Clean or replace the air filter if it's clogged. For Internal Error, Fan Error Sensor Error or Auto Iris error, stop using the projector, disconnect the power cable, and contact your local dealer or the nearest address provided in the Support and Service Guide.
