No do not reset the lamp hrs. because the lamp might reach the ed of life and could blow resulting in mercury poisoning. If you notice there is a warning sign that pops up in red or something saying to change the lamp, it will shut down eventually during that warning time. You have gotten a lot of hours with that lamp and consider being fortunate to have such reliability. Buy a new lamp when needed as it will improve your experience.

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:

TV IS ON HAS SOUND BUT NO PICTURE


This looks to be a DLP device, meaning it has a high intensity light source such as a halogen or mercury lamp. The lamp has probably failed, These lamps usually fail after 2000 or 3000 hours of life and can cost upwards of $300.

When I plug in my infocus 70+ to the laptop the bulb changes to a green light and the presentaions become greenish. How do I fix this?


reset the settings to factory default. if it doesn't change, make sure the colorwheel is in yact. then check the lamp hours (in the menu option). if it's close to 3000 hours, replace the lamp. also replace it if it has bulges, black spots, fogging or flaking. when it's on it's way out, the voltage drops and that effects the light temp. if the lamp is new(ish), you may have a bad ballast. if that's the case, you can get one from an infocus service center. try av solutions in ny. they're really good. www.avsolutionsny.com

Lamp and temp lights come on after power up and stay on. Lamp only has 330 hours on it.


OK, that explains it. The bulb you have installed in the projector might be the original bulb that came with the projecoter when it was new. Just becuase it states 334 hours does not mean it is new. In fact, you could have a original bulb with 3000 hrs and reset the hour timer on the projector, which means your 3000 hour bulb might have 3334 hours on it because the person who owned it before you, reset the hour timer.. Best bet, buy a new bulb and reset the hour meter and see what happens. If you have the same problem, then your ballest might needs to be replace which is rare...

I wanted to know how to tell how many lamp hours are left on a NEC VT47 LCD Projector- also how does the lamp hours work? if you have 2000 hours does that mean the lamp life is over or you have 2000 hours...


if the bulb has 2000 hours that means it is supposed to last 2000 hours of continual use. It is hard to keep track of the lamp hours though unless the projector has a timer built in. It depends on the manufacturer as to if it is telling you 2000 hours left or used. There should be a way to switch this. But a lamp rated for 2000 hours has 2000 hours of being on is expected lifetime

Sony cineza vpl hs51 projector won't project


Something I found interesting from the internet - lamp life isn't when the bulb dies, but when a bulb has lost 10% of its brightness - so you might well be able to reset the timer and get much more use from the bulb - the image just wont be as bright.

The lamp may not have been changed - just the timer reset - How many hours has the lamp really done - 1000, 3000, 5000?
If you know that the hours are genuine, then was the quartz bulb contaminated with a touch of oil from skin contact?
This will substantially shorten lamp life, due to the quartz going milky and opaque.
The easiest way to check, is to pull the lamp and have a look at the bulb.

If need be replace the lamp and reset the lamp timer.

These instructions are for a Sony Cineza VPL HS3, but may be the same for the HS51
1st thing to check - is the cover properly/completely closed - this can stop the projector from working.
Connect the power and set the projector to standby mode.
Press these buttons on the remote control in this order, for less than 5 seconds each.
Reset - Left Arrow - Right Arrow - Enter

Infocus 4805 blinking red light problem


My first questions is:

Is this the first lamp you have placed into your Infocus pj? If not, did you reset the hours when you did it last time? Otherwise that can also confuse the projectors internal system thinking there is NOT a new lamp in there and there for make it stop working once the clock hours are expired and over the 3000-6000 suggested hour life.

Let me know so I can help trouble shoot other possible problems.

BenQ PB6100 extremely dim screen/projection


Hi skeeterJ

This is most probably your lamp , I have had loads of PB6100 's that has even had less hours on the lamp than yours and needed replacement.

Keep in mind that the 2000-3000 hours they talk about on a lamp is just a rough factory estimate. The time you get on a lamp is determined by how you use the Projector - because at the end of the day the lamp is just like a globe in your home - it doesn't like being swithed on and off for short periods. This is a mistake most Projector owners make - by thinking they are saving the bulb's lifetime and switching it off for short periods.

You can take my word on this as I am a Authorised BenQ Service Technician.

I've had clients who got 10 000 hours on one bulb just because they left the unit running for longer periods.

Lamp Part No : 60.J8618.CG1

Easiest way to make 100% sure before investing in a new lamp is to take out the lamp by opening the lamp door at the bottom.
Check for any vein like looking marks in either white or black or a bubble on the shaft.

If you have any further troubles or questions , feel free to post another posting and I'll answer it for you ASAP.

Thanks for using Fixya and good luck !

Lamp


Hi Striker 53

Yes , a flickering image and dimming is a very clear indication that the lamp is going.

To make 100% sure and to give you some peace of mind - take out the lamp and you will either see vein like looking marks on the lamp or discolouration or even that there is a bubble at the end of the lamp's shaft.

Do keep in mind that a lamp normally gets a rating of say 2000-3000 hours , but that is only a estimate from the manufacturers factory. I've had lamps that had less than 300 hours on them , that needed replacement.

Once you replaced the lamp , remember to reset the lamp timer.

No picture, hear sound, television will shut off after a few seconds.


Lamp life is only a few thousand hours. Hopefully its only the lamp that made to noise. Don't turn on again until lamp is replaced.
