Question about BenQ PE7700 Multimedia Projector

1 Answer

Projector shuts down after turned on and both red lights blink

I have a benq7700. When I turned it on everything started coming on like it was suppose to. Fan came on (but was a little louder than normal), the screen lit up with the benq logo start up, then it all shut down and the temp light and the lamp light both started blinking red. Unplugged it and waited a while and tried it again. Same thing happened.

Dell 1209S Projector, tries to turn on, and the fan comes on for 30 seconds and then goes off again. It tries this several times and then the light bulb icon comes off and it doesn't do antything else


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™.

Red power, blinking red temp


Hi,

if the Lamp error and Temperature error lights are flashing red this means that there are two separate errors.

  • A flashing lamp light means the lamp failed to ignite. It could be a lamp driver problem or lamp failure. Replace the lamp to resolve the issue. If the issue is not resolved, then service the projector.
  • A flashing Temperature light signals a fan error. Turn the projector off and allow it to cool down. If the light is still flashing after the projector is turned back on, service the projector.
Goodluck..

Projector screen turns off after 10-20 seconds


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?

New bulb worked for a short trail run now wont light up. flashing green led colour wheel is turning on start up


when you changed the lamp, did you blow the dust out of the projector? if the screen on the side of the lamp is blocked (i.e. with dust), the lamp will blow quickly. if the projector were to overheat, by the fans not running or blocked vents, everything would shut down and the led would blink red.

EIKI XB23 PROJECTOR WON'T GO ON


Do you hear the fan start up? or does the projector lamp come on (you start to see an image)?

If yes to either:

When the temperature inside the projector reaches a
certain level, the projector will be automatically shut down
to protect the inside of the projector. The POWER indicator
is blinking while the projector is being cooled down. When
the projector has cooled down sufficiently (to its normal
operating temperature), it can be turned on again by
pressing the POWER ON-OFF button.

Note:
After the temperature inside the projector returns to normal, the
WARNING indicator still continues to blink. When the projector is
turned on again, the WARNING indicator stops blinking.

Then check the matters below:
– Did you provide appropriate space for the projector to be
ventilated? Check the installing condition to see if
ventilation slots are not blocked.
– Is the projector not installed near the ventilation duct of
air-conditioning equipment which may be hot? Install the
projector away from the ventilation duct of airconditioning
equipment.
– Are the air filters clean? Clean the air filters periodically. Let me know if you need to know how to do this.

If no to either:

When the projector detects an abnormal condition, it is
automatically shut down to protect the inside and the
WARNING indicator will be red. In this case, disconnect the
AC power cord and reconnect it, and then turn the projector
on once again for check. If the projector cannot be turned
on and the WARNING indicator emits a red light, disconnect
the AC power cord and contact the service station for check
and repair.

Please let me know if this helped solve the problem. If not, is there anything else you observed - whether or not you believe it's relevant.

My projector doesn't stay on. what's wrong?


either the lamp cannot strike (meaning a ballast or lamp issue) or there the fans are not up to speed to sufficientl;y cool down the lamp and therefore shut down to avoid damage.
