Epson projectors - lamp issues
Lamp changing issue with regard to Epson projector models:
PowerLite 5350, 5500c, 5550c, 7250, 7350, 7500c, 7550c,
The firmware in early release projectors of this model range may have an issue when replacing the lamp. The problem occurs only AFTER the warning light changes from alternately blinking red and orange, to steady red.This happens when the lamp reaches 2000 hours of use.
1) If the lamp has less than 1900 hours, the lamp indicator on the projector will be off – no firmware issues. The lamp can be replaced if it burns out or the image brightness weakens.
2) When 1900 hours is reached, the projector’s lamp indicator will alternately blink red and orange indicating that the lamp should be replaced – no firmware issues. Replace the lamp before it reaches end-of-life at 2000 hours.
3) When 2000 hours is reached, the projector’s lamp indicator will change to steady red – at this point, the firmware should be checked before replacing the lamp!
