If you press the power button on your Acer projector but it does not turn on but the power button flashes red and blue then this is almost always the Lamp. In rare circumstances there may be another issue.
Check the lamp If you remeove the 2 small screws underneath your projector this should allow you to remove the lamp. If you have replaced the lamp with a new lamp and it still does not start this may be a fan issue or even a lamp ballast failure.
