Table B-3. Red LED behavior and projector errors
Red LED behavior | Explanation |
|
|
One blink | The lamp will not strike after five attempts. Check |
| the lamp and lamp door installations for loose |
| connections. |
|
|
Two blinks | The lamp counter hours have exceeded lamp life |
| hours. Replace the lamp and reset the lamp hours |
| counter. |
|
|
Three blinks | The projector has shut down. Check to see if the |
| lamp door is open. If the lamp door is closed, toggle |
| off the projector and wait one minute, then toggle |
| the projector on again. If the lamp does not strike |
| after one minute, replace the lamp. Contact IBM |
| technical support for repair, if replacing the lamp |
| does not solve the problem. |
|
|
Four blinks | The fan has failed. Contact IBM technical support for |
| repair or replacing the fan. |
|
|
Five blinks | The projector is overheating. Check for a blocked air |
| vent. Contact IBM technical support for repair if |
| clearing the air vents does not solve the problem. |
