Question about BenQ PB6100 Multimedia Projector

Blue-ish tint suddenly ?

I have only 900 hours on my lamp and everything has been beautiful since I bought this 6100 3 years ago. Now, for some reason, the projected image, no matter what the source, has a very blue hue ! What can I do ?

    Thanks, but what do I do next ? How to be certain ?

    And, after 3 years, how could this LCD panel just stop working ?



  • videoman49 Oct 13, 2008

    I bought in online. :-(

    Couldn`t it be something else ? something simpler ?

  • videoman49 Oct 13, 2008

    Clean the air filter ? Uhh, never heard of that before.

    So, is there a way to solve my problem short of buying this panel ? if not, can the panel be bought online and then installed by me ?

    Hi again

    I`m still hoping for a reply to my latest post.


  • videoman49 Nov 11, 2008

    I bought the unit online.

    LCD panel huh ?

    I guess I should ship it back to BenQ and let them look at it ?

    Isn't there a way to find a local authorized repair shop ?

    Thanks !


  • videoman49 Nov 12, 2008

    I emailed BenQ and received a reply that was WAY off base. It had nothing to do with my question.

    I am not optimistic that they can be of help to me.

    So, I`m hearing bad or broken color wheel from the FixYa expert I paid for .. and others, like you, say it`s the LCD panel ?

    I`ve also heard that BenQ doesn`t have these parts because the PB6100 is obsolete now.

    Sheesh .. I don`t know what to do.

  • videoman49 Nov 17, 2008

    Hi .

    OK, do I try the Soft Reset BEFORE unplugging it ? or after ??



  • videoman49 Nov 18, 2008

    I`m through trying these re-sets. They don`t work.

    Since someone else said it`s probably the color wheel, I decided to unscrew the panel on the bottom and see what`s inside. I have removed the lamp and found the color wheel. Now, does anyone here know how to evaluate the integrity of this wheel ? Can anyone advise me on what to do next ?

The solution is as its follows: :)enter in

Factory Menu
1. How to enter factory menu:
2. Hold press "UP" button until the "Lamp hours info." OSD display on bottom-right of screen.
Press keypad <Power> and <Blank> key simultaneously again, then enter Factory menu.
enter in fan menu and increse the speed of fans. -> had to use the already written text...:P

3. with the keypad look for the menu that says <more options> on the bottom of the osd. once you are there go for the option HARD RESET.

4: also look for the option where its says SOFT RESET. its on other tab ... shut down the projector. take the power cord off the 6100. wait for about 10 seconds. plug it again and there you works again.!!

    Hi :
    i just realize that there´s no SOFT RESET option its called DATA RESET. sorry.... jeje little err.....

    and you have to do the unplugging after both resets.... also take note of how many hours your lamp has ´cause after the reset everything goes to zero.

    Good Luck

Possible defective LCD panel(s) in the projector

    Your next option is to take it to a service center, preferably where you bought it. They can examine the LCD panels to be sure if one or more is bad.

  • Don Roth Oct 13, 2008

    most LCD failures are brought about by overheating, usually caused by not cleaning the air filter(s). another cause of overheating in my experience has been unplugging the projector before it has had a chance to go through its cool-down period after the lamp is extinguished.

    LCD panel failure has been the most common cause of "all one color" images in the projectors that have crossed my bench. there have been a couple of isolated cases where the inside of the projector was so dirty that light wasn't able to get through one of the panels, thus robbing the picture of that color.

  • Don Roth Oct 13, 2008

    LCD panel replacement is a touchy operation for those of us who have done it before; I wouldn't recommend it to the novice. I don't have any experience ordering BenQ parts; they may not sell to non-service customers.

  • Don Roth Nov 12, 2008

    Call BenQ and see if they have any authorized repair centers. They may want you to send it to them. I've never worked on a BenQ, but the problem you describe sounds like some Panasonics I have repaired which had defective LCD panels.

BenQ warrants their lamps at 500 hours...I had one go at 420 hours for my projectors, had to contact the company for a return number and pay to ship the entire unit back to them, then they sent me my unit back with a new bulb installed. Process took about a month.

fisrt, did you reset the lamp timer? if the projector turns on again, go into the menu settings and reset the lamp timer. 3 flashes also mean that the lamp is too hot. let the projector go through it's cooldown mode and shutdown before you unplug it. remove the filter case and vacuum or blow the dust out of the filter. you can also blow the dust out of the projector (if any) with canned air. lastly, be careful where you buy lamps from. you get what you pay for. cheaper isn't always better.

your color calibration may be off. see if you can set the red green and blue settings all to "0" and see if that works. may want to refer to your manual and see how you can do that and also see if there is a auto calibration
