We contacted BenQ's technical service people from the toll free number on their website. They had us do the same thing the manual said to do and of course the lamp hours would not reset. We had to send the projector to them and they responded that our mother board went and that it needs to be replaced. They've quoted us around $180. What happened to us was that we didn't change the bulb when the warnings came up on the screen. It isn't explained anywhere that if you wait til you get to 3000 hrs without changing the bulb that you could screw up your machine, but it's kind of looking that way. If I were you guys, I would make that call to their tech support and see what they tell you.

The lamp does not attempt to turn on anymore on my Runco VX-1C projector. Power to the projector is good but lamp does not turn on.


I was about to chime in that you should reset the lamp hours after inserting the new bulb ... until I read that you couldn't see the menu because the bulb still doesn't turn on. Hmmm...

Have you checked all of the filters to ensure they're free of dust build-up? I'm wondering if it overheated which caused the fault.

Due to the fact that this model is out-of-production your options have become limited. I recommend at this point you give them a call:

Lamp didn't strike


Hi,

lamps are affected by strikes. each strike erodes a part of the anode. so in essence, the lamp wears out. However a Xenon has a much longer hour life as once it is running, it cares "relatively" little about how long. SO for commercial units, this is an advantage. there are also larger potential issues about colour stability over life.

with UHP, they care only minimally about strikes, it really is not even a strike, so while frequent on and off can kill it early, with normal usage, you are going to be fine. However with a UHP, if a lamp runs for longer times... then you have issues. THe way i had it explained to me was as such;
With a UHP, it gets up to proper operating temp in about 5 mins. once it is there... it SLOOWWWLLLLLYYYYY continues to heat up. After about 2-3 hours, it starts going outside the nominal operating range. once it does so, it starts to degrade the lamp. thereby lowering life expectancy. if you shut it off after about two hours or so and let it cool for ten mins then do it again for two hours... you are in a much better place. In a grand scheme, apparently if you run the proj for an average of 4-6 hours every time, then expected lamp life goes to about 50%. THis is very rough and in a general sense so just take it as general guidelines.

TIPS TO EXTEND PROJECTOR LAMP LIFE:

Lamp life for a projector will vary based on many factors including application, installation, intake of cool air and exhaust of hot air, usage, and proper maintenance. Heat buildup can reduce lamp life and even damage your projector. Here are some tips to help your projector lamps last longer.


Once you turn on your projector, wait at least five minutes before turning it off to allow the fan to properly cool the unit. After the fan has cooled your projector, you may unplug it and store it as desired.

Do not obstruct the air intake or exhaust vent. Paper should not be placed on top of a projector, or where vents are located.
.
Keep the exhaust vent at least two feet from any object.


If the projector is built into a compartment, wall, ceiling or shelf mount, the minimum distance requirement (usually at least two feet) stated in your owners manual must be maintained.

Clean the projector's air intake filter every three to six months -- or more frequently -- based on your operating environment.

Do not move your projector until the lamp has cooled (about five minutes).

Run your projector for two weeks and/or 20 hours shortly after your purchase. If the lamp is going to fail, it will usually occur within the first ten hours of operation. Lamp warranties typically last just 90-180 days from the date of purchase, rather than the first installation.

When you purchase a replacement lamp for your projector, remove the existing lamp and use the old lamp as your spare. If your projector is new, test the original lamp for the two weeks/20 hours before removing and storing as a spare.

I hope the info. which i have given you solves ur problem if not i am sad to say you have to get it repaired..

Goodluck,

Can't reset lamp timer after lamp replacement on Panasonic PT-AE40000


I have a Panasonic PT-AE4000U and could not reset the timer after replacing the bulb with a, non-Panasonic branded bulb. Calls to tech support were not very helpful. It was another bad customer service experience. Through troubleshooting it myself, I discovered the solution was simply to unplug EVERYTHING (serial cable, hdmi cables, etc.) from the device, power it off and back on. Follow the procedure in the manual, the timer immediately reset!!

Infocus LP725 Replacement Bulb


if you don't know exactly how many hours are on the new lamp, you can't be sure it works. since it's a mercury lamp, there will be no contenuity. check the lamp for cracks or clouding, not just burn marks.if the lamp is actually good, you may have a ballast issue.
