Lamp is burned out or makes a popping sound. When the lamp reaches its end of life, it may burn out and may make a loud popping sound. If this occurs, the projector does not turn back on. To replace the lamp, see on page 38. LAMP light is solid amber If the LAMP light is solid amber, replace the lamp. LAMP light is blinking amber If the LAMP light and the Power light are blinking amber, the lamp driver has failed and the projector will automatically shut down. If the LAMP light is blinking amber and Power light is solid blue, the color wheel has failed and the projector will automatically shut down. Unplug the power cord after 3minutes then turn the display on again. If this problem persists, contact Dell™. TEMP light is solid amber The projector has overheated. The display automatically shuts down. Turn the display on again after the projector cools down. If the problem persists, contact Dell™. TEMP light is blinking amber A projector fan has failed and the projector will automatically shut down. If the problem persists, contact Dell™.
Please do not unplug the power cord before POWER is shut down or during the two-minute cooling process.
If the projector is not properly shut down, to protect the lamp, the system will detect this and cool the lamp for two minutes automatically before turning on again.
Check that you are doing this.
I suspect that this is not your problem though.
It seems that the blue light doesn't flash very long. do any other lights come on during the startup process.
Is the projector receiving a source signal? if not it will power itself down after whatever time you have it set to do so when no signal is present. Just an idea?
Here's the fix: Take off the top cover of the projector. Unplug the
wire leading from the two fans in the back of the unit to one of the
circuit boards in front of you. Just trace one wire from fan to board.
Unplug at board. Turn unit on and it will again turn on, show HP splash
screen and then shut down, like it should, because the fans are now
disabled. After it completly shuts down, plug the fan wire back into
the board. Turn the unit back on and, presto, its working again. It
will not turn off.
Have you cleaned the filters? In this situation, the fan and power shuts down even before the bulb lights up and heats up the unit, but perhaps the unit can detect clogged filters.
You can download the manual here if you don't have one. Instructions for cleaning the filters are on page 37.
Have you resetted the lamp timer ? It must be done when a new lamp is inserted into the unit.
You can reset the lamp timer by holding the up arrow key on the Projector in until a online message appears. Then just follow the on-screen instructions.
If the problem persists , you will have to replace the Ballast wich is the lamp's power supply.
