Just got a BG800, and the overall conditions look fair even though the "run time" shows only 1108hr. I'd like to check the tube condition, but don't know how. Please help! BTW, where can I find a service manual for the unit?


Thanks a lot,

Lei

Hi Lei, and welcome to the Barco family! If you are checking the tubes for burns, the best way to go about it is to remove the lenses from the front of the projector, and look at the tube faces directly. Another (however, can be less effective) way to do it is to use a good flashlight and look through the lenses, sweeping the light over the tube faces one by one to look for wear patterns or a more distinctive brown discoloration indicating tube burn.


Hope this helps!

Hi Darrin, how to remove the lens? is it described in the service manual? where can I find one?

Hi Lei,


The removal of the lenses is made easy by lifting the cover on the PJ AFTER you have powered it off (or removing it all together).There are four black nuts located at the corners of the plastic lens housing of each gun; conversely, they could be long, almost bolt-like in appearance. In either case, you need a, um...hang on a sec...


(Insert "Girl from Ipanema" muzak here)


OK, you need an 8mm or 5/16" socket to remove the nuts (and be careful not to lose one into the PJ. This is why I recommend powering down the unit, just in case).


Unfortunately, I don't have the service manual for the BG 800, so I can't help you there. Use the forum search function to look up manual for the Barco. You may be able to come up with the installation and users guide.


Cheers!

Okay, the lens are removed now. The green and red tubes look fine, but the blue one looks white with some yellowish in the center (power off). Is it normal? when powered up, the green tube flickers a little. what could cause that?


Is there a way to tell if the tubes are original or changed? what does the "run time" indicate? tube hours or chasis hours? are these numbers resetable after tube change?


Thanks for any input,

Lei

Lei , the yellowish on the blue tube is wear. To see if it is destracting, project a full white screen and see if it shows up with a yellow pattern. You can alway try to adjust the screen size/projection distance so that your image will fall inside the wear pattern. I dont know about the flickering in the green tube, maybe someone else can comment on that. About the tubes: every part has a little badge on it wearing the serial number. Check if the numbers correspondend. The run time indicates the chassis hours. tube time will be lower. It is not possible to reset the run time indicator in a normal way.


Good luck with your Barco, sure you will enjoy it !
