My BenQ FP71G Monitor has been turned off for 2 weeks on starting it this morning I have fine colored lines that cover 1/3 of the screen on the right hand side.I have checked the cables. Have you any...


You have failing LCD panel or the 5vdc feeding the panel may be bad. Check to connection at the LCD panel T-CON board.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Screen will not stay on


There are two places to look for the problems, the backlight inverter board and the power supply, look for burnt parts, bad capacitors, etc.

Screen has power but is black


Looks like many faukty parts on the inverter board.. replacing will not be of much help as it will soon start get troublesome once again. I would suggest that replacing the LCD inverter board is a smarter solution. Hope this helps!
Good Luck!

Calibrator talk doesn't see monitor on mac


did you verify that the USB port is active and the cable is working? Check under the Apple menu for "about this mac" then click on more info. Click on USB to see a list of active USP devices. If the Barco is connecting it will show up in the list. May not say Barco, it may say unknown device but it lets you see that the cable and port are working. If not replace them or try it on another computer. If they are working then the Calibrator Talk software may be configured wrong, have you contacted Barco? They have a troubleshooting area on the web site.

Benq screen shuts down when pc is plugged in


If it's a 71g and not 71g+ resolder transistors 2sc5707 on invertor board along with grey condensers and inverter transformer.This should solve the problem if it was display shutting off with power led remaining on.Otherwise check power section.
