My projector won't project anything. the computer recognizes the projector, but the projector does not recognize the computer. also when i turn on the projector the benq logo doesn't show.


Disconnect all inputs to the BENQ and power on. Do the lights come on as per normal operation. Does the lamp come on when the power button is pressed. Does anything show when the menu is selected.

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


Hi!
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!

Connecting to a projector, presentation mode is


Try right clicking on your desktop, go to properties, then settings, you should see display 1 and display 2, right click on 2 and select attach.

If its not there press FN+F8 a few times, also look for the presentation software that came with your laptop and see if it has the feature to turn it on.

Acer 4736 compatibility with eb-s6 projector in usb display mode.


Check the Microsoft knowledge base for a "workaround" for this issue.
Try doing a search for "device not recognized" there should be several steps to correct this issue. However this may be due to compatibility with your projector and the usb port drivers. Contact the manufacturer or go to his website for driver and usb information on your Projector ability to connect to your Acer. Good luck!

BenQ 8700 projector solution


Hi Rick

The upgrade is the same one used for the BenQ PE8720

Whoever told you this obviously did'nt know this.

You'll be needing Flashloader and the RS232 cable that came with the Projector.

It is absolutely cheeky of them to suggest that you should just use the Component input for all your applications on this Projector.

Make sure they understand that this was a top of the range Projector when you bought it and that it is not a good enough answer.

Zebra Z4MPlus doesnt communicate with PC


Ok,

This machine has a parallel port. Try to print via parallel cable. If it works, consider staying with it. Serial ports are a pain to manage.
If you absolutely have to do it via rs232 though....
Question 1. Has it ever printed?
If yes, Go into Windows Printers and Faxes control and select the Zebra or whatever printer that you are using. Right click on it and you should get a menu that at the bottom say "Properties", select that, then you should get a new window with tabs at the top. You want the tab for "Ports". Select it and you will see all of the different output ports that you can direct your printing. RS232 is a COM port. So start at COM1, check it and try to print. If that doesn't work, go to COM2, etc.

Last resort, If you can't get control via the printer driver program, you will have to try redirecting the print manually (now you will understand why I said to stay with parallel output).
What you have to do is redirect your printing via the dos "mode" command.
Under "Start Menu" goto "Run" and put in "CMD" and click "OK".

This opens a black square window with a cursor blinking. Type in this:
mode com1:9600,n,8,1 (enter)

mode lpt2=com1 (enter)

Tell your program to use LPT2 if you can and see if it works.
By now a parallel cable instead of RS232 should be looking really good.
Good luck!

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%
