Hi all

First time here .. hoping someone can help me out.
I have a BenQ PB6100 projector. It`s been great for 3 years, but now I`m seeing a blue hue all over the projected image, no matter what input source I use. BenQ doesn`t have any support so I thought I`d try you guys ..
Does anyone know what might cause this ? (my bulb has only 900 hrs, incidentally)
I appreciate any help ! :-)

Thanks,
Mike

Thanks for your help, Blaast. The thing is, after the warranty is over, BenQ is going to charge me a fee to help me solve this problem. :-(

Mike,

If you pull up the menu is it discolored as well? If so, you have an internal issue - probably a broken color wheel. If the menu looks fine, try a new cable and source.

Please indicate what input connections you are using that show this coloring and as was requested above, does the menu show this blue color as well?

Mike, go into the service menu and do a HARD RESET. I have had to do this at least a half dozen times on my PB6100. Mine is 4 1/2 years old with about 2500-3000 hours.

You will lose all of your settings and the bulb counter will reset to zero, so write down all your info. If you have any questions let me know.

Hi guys
I appreciate your help, very much. :-)
How do I do this HARD RESET from the service menu exactly ?
And, no .. the menu that comes up on screen is NOT discolored at all.

One thing I read in the (lame) manual from BenQ is that the System (NTSC or PAL) might be incorrect. Well, in the menu I can see these choices, but they don`t highlight and don`t respond to changes in any way. I wonder .. could that be an issue also ?

The cable couldn`t have suddenly just gone bad, could it ? I`ll replace it if necessary, but .. seems odd that a cable wouldn`t work suddenly.

Thanks,
Mike

Hi
I`m using DVD or Comcast TV inputs, with a switcher box connecting everything. I`ve tried to isolate by going around this switcher and trying each source independently, but still the same blue-ish color.
:-(

Ok, if the menu does not come up Blue then you have a connection problem. Are you using component cables? Red, Green, and Blue? Recheck them to make sure they are all connected properly.

Ok, I just looked at the user manual and it looks like you just have s-video, composite, and vga.

Have you tried running a cable straight from a source to the PJ? Ok, you ansered that too.

Which connection are you using of the three I mentioned above?

In the Menu, System .. I see NTSC, PAL, SECAM and, for some reason .. YUV seems to be highlighted ! This doesn`t seem correct. Could this be an issue ?

Incidentally, upon closer examination, it does seem that the pop-up menu IS tinted blue a bit also. What can that mean again ?

All my cables are connected properly.

Back to you ... thanks.

Hi,
Thanks again !!!
I`m using a large multi-pin at the PJ itself to red-green-blue on the other end.
Oh, and the menu does seem to have a blue-ish hue to it, now that I looked closer ..

In the Menu, under System, shouldn`t NTSC be highlighted ? It isn`t. YUV is.
Any idea what that means ?

In your source menu, what is your source set to? PC or YPbPr? Try switching that.

-MikeYUV means it's probably set to YPbPr in the source menu.

To get in to the service menu: On the projector, push and hold the exit button . When the lamp hours show up on the screen press the power and blank buttons together on the projector. The service menu should come up if your timing was good. You may have to try a few times.

There are are 7 menu pages. Using the remote to navigate, go to the last one on the right. Press down on the remote to get into this section. At the bottom there is a choice for more options. Pick it. At the bottom you should see HARD RESET. Pick it. Thats it. Give it a shot you can't hurt anything by trying.

I'll check back later for updates. Good luck.

If the switch in the source menu does not correct the issue, I'd give Jason's recommendation a try. As he says it couldn't hurt.

Make it 7 times that I've had to do a Hard Reset. When I turned it on tonight I had a red screen. The picture is ok for a second when it syncs on a signal, then it gets a red haze/film to the hole picture. A Hard Reset fixed it again.

Mike, I fixed the instructions on how to get into the service menu in my last post. It only takes a minute and hopefully thats all thats wrong with yours. Let us know how it turns out.
