Projector problems Hi, I have a 3m MP7730 projector that keeps going into standby mode. I switch it on and it works fine, it warms up and after 10 seconds of projecting the lamp switches off and the projector goes into standby mode. There is a lamp indicator that keeps flashing.. and the instruction manual says that the indicator flashes when the lamp is too hot. But the projector won't stay on for more than 5 minutes and it doesn't seem over heated. Any ideas? Thanks, Maria

Re: Projector problems


After 2 years I finnaly solved the problem. There was a flaw in the lamp´s temperature circuit. A technician disassambled my BENQ PB8253 unit and fixed the problem. Charged me US$ 75.00. I´m in Brazil.

Hope this can help.

Re: Projector problems

Hi David IB

I've had teh same experience with a BenQ MP720 ( just the XGA version of your Projector )

I queried this with BenQ Engineer in Dubai and he said that it sometimes works exactly like a short on the machine.

If I could give you a tip , If it happens again don't put back the metal cover of the Mainboard it solves the problem 100%

Why does the projector keep going to standby mode?

If the lamp usage time has passed 2 000 hours (when LAMP POWER has been set to NORMAL), the projector will switch to standby mode after approximately 10 minutes of operation. The resetting procedure should thus be completed within 10 minutes.

1. Insert the power cord plug into the wall outlet and then

press the MAIN POWER switch.

2. Press the POWER button so that a picture is projected onto

the screen.

3. Press the MENU button to display the menu screen, and

then press the F or G button to select the OPTION menu.

4. Press the ENTER button, and then press the F or G button

to select LAMP RUNTIME.

5. Press and hold the ENTER button for approximately

3 seconds. The confirmation screen, "LAMP RUNTIME

RESET." is displayed and select OK.

6. Turn off the power.

This will reset the cumulative usage time for the lamp
unit to zero.

Miss operation to launch "Control

When the control panel lock ON of the projector so that the projector can be operated only with the REMOTE CONTROL.
If you loos your remote control then keeping the POWER key on the projector control panel pressed for 10 seconds turns the projector ON when it is in standby mode, and turns the projector to standby mode when the power is on. If you press and hold the MENU key for about10 second when the power is on the lock will be released and "panel key lock" is automatically set to "OFF"

Changed my projector lamp yesterday, it work for about 4hours and went on standby. its now on a stanby mode and all effort to switch it on has not been successful. Please help me

Is your projector connected to a source? ( Computer, DVD, or any device) make sure the connection is tight/properly plug in so that the projector will recognize the device attach to it and override the standby mode.
Hope this helps, thanks for contacting Fixya. Please keep us posted of issue. Cheers!

The projector is going into standby mode 30% of the way into the presentation. This is not my projector so I'm guessing at the setup. Can you help. I'm using my laptop with a PowerPoint presentation,...

check the settings. sometimes there is a shut off timer if it isn't used for a specific amount of time. you can turn that setting off in the menu (if it has it). otherwise, it may be overheating and needs to be cleaned out with canned air.

Reset Lamp Hours Timer

This works on a couple different Toshiba models -- might work on yours...

Make sure the main power switch is OFF. Hold the "ON", "MENU", and "INPUT" buttons at the same time and turn the main power switch on. Keep them held until the yellow power standby light comes on, then let go. It is done.
