Question about NEC (50019497) Projector Lamp for VT440, VT54

2 Answers

NEC Projector VT440

Used every day in our school. Recently had new bulb and has had polariser replaced in the past. Image is fading, adjustments to colour, etc. makes no difference. Video is Ok-ish but image from computer is terrible, very faint and white background is blue-ish. Any ideas that won't cost a lot?! We have to decide now between spending more money (we've had this one about four years) or buying a new one.

    My projector sounds like it's working but no image comes out. If I shine a light down the front barrel I can see the image of my computer monitor so I think it is just the bulb. The problem is I can only find whole lamp mechanisms for sale $510. Does any one know how to just replace a bulb and where do I get them?

I am a computer and electronics tech for a school district. I have worked on a number of different model projectors. The biggest problem that I see that can wear out a bulb VERY FAST is dust in the filters. When the filters get clogged with dust, the projector cannot move the proper amount of air to keep the lamp cool. These lamps run extremely hot and if not cooled properly can fail very fast. The first sign of a failing bulb is that the picture gets very dim. This is a good sign that the bulb needs to be replaced.

Another thing that can reduce the life of the bulb is leaving the projector on when it is not in use. If you are not using the projector for an extended period, shut it off. Leaving the projector in an A/V muted state does not shut down the bulb completely and can still wear on the lamp hours. These bulbs are rated for a certain number of lamp hours, so any time the projector is on, it is wearing away the hours of useable time. And at the cost of these bulbs, this can get expensive.

Most companies that sell bulbs sell the entire bulb assembly which is the bulb in an easily removeable housing that is usually made of a heat resistant plastic. One place that I use for replacement lamps is a site called my projector lamps http://www.myprojectorlamps.com. This site will sell you the entire bulb assembly for a reasonable price. If you feel confident enough and have a bit of mechanical ability, you can usually get the bulb alone at a cheaper price and replace the one in your existing housing. Bulbs for some of these can be a bit tricky to replace in the plastic housing, so check out your assembly before going and ordering just the bulb. You may want to even try getting the bulb out of the housing first to make sure you can do it. That way if you damage the housing in any way you can then order the complete assembly.

SOURCE: NEC vt440 projector is overheating

Try cleaning the filters, there is one on the front and one on the side. When dust builds up on these it can restrict the cooling of the projector

Try pressing the HELP button. Don't release and press the power button. The LED lights should blink. Release then try to power on again.

SOURCE: I have a nec 1050.

It sounds like a polariser lens has failed, if so it may be cheaper to purchase a new projector than have it repaired.

Hope I was of assistance to you

Epson 822+ Projector still dim after replacing bulb


I'm not familiar with your specific model, but are the units LCD or DLP? What I've seen in LCD projectors used in schools, museums, etc. that are left-on for several hours per-day, is that the UV filters in the optical blocks will fail. They usually change to an amber-brown color and block most of the light. It's the equivalent to putting sunglasses on. Do the units also exhibit a greenish-yellow tint instead of proper color?

The image is made up of three polarisers, one tends to fail causing a problem with the image. On average it may cost £300 per polariser to be fixed. As you know these days you can get a projector for that price as everyone now wants HD and 3D. I recently bought 7x NEC NP115 for just over £200 each. Very good spec, auto power up (Which was important for what I needed)

hope that helps

It sounds like a polarising lens has failed, if so it will probably be cheaper to buy a new NEC NP115 which has probably got the same if not better specification.

Hopefully I was of help to you

Seeing a blue "haze" on presentations, and when on blank screen


On the "Option" menu, try selecting "Service" and the "Factory Reset". This may help. If not, you will have to use the menus to manually adjust the level of blue in the projectin. Go here for the manual for your Hitachi and you will find instructions:

Optoma EP732H Projector - Image is Whitewashed


Hi tourblack

I wouldn't think that this is a lamp issue , as the lamp will make the picture fade away in brightness and wouldn't look white washed.

Check if the brightness is set to 50% and the contrast on 50% as well.

This could be a colourwheel that is in need of replacement.

Hello:
It sounds like your light engine needs replaced, should be around $400.-600. depending on who does it. I have seen the lamp cause similar symptoms but not that likely.

My Ricoh 3035 / Savin 8035 prints uniformly light pages, and tells me to add toner, with a FULL toner bottle. The developer unit itself is completely packed with toner. There are no other errors set. The issue described is recent, within the last 500 copies. Prior to that this machine was running perfectly. I've had this copier for a couple of years. It was used. It NOW has 617,871 prints/copies/faxes as of today. I replaced the developer unit remanufactured and new developer at 591,810. The transfer belt and cleaning blade are new at 607,638. I replaced the PCU with a completely remanufactured unit at 607,688. The fuser was replaced with remanufactured unit also at 607,688. I was STILL having some issues with bad quality copies, so I narrowed the matter down to a defective drum in the remanufactured PCU. I replaced the drum, and at THAT time, I installed every part in the Savin Maintenance Kit PMB082150K, which I previously received with the copier. I also replaced the PCU Entrance Seal and tape the long mylar one at the top of the drum. When I installed the developer unit, I initialized the settings, pursuant to the Service Manual, and the same with the drum, and the appropriate one each time I previously cleaned the ID Sensor Today, I went through the trouble of replacing the ID Sensor, initialized the same, and it made no difference. The copier has run just fine for the last couple of months, and then as I stated in the question, about 500 copies ago, all of the copies suddenly became light. No, it's not the density setting. I've done everything except do a factory reset. Incidentally, I have the Ricoh 3035 Service Manual, and also the Parts Manual. Experientially, the only computers I have ever purchased are 2 of them, for my office, in 10 years. Other than that, I have built every computer I've ever made, from parts. As far as this copier, I have done the copier maintenance, per the maintenance schedule, myself, and when it appears that maintenance needs to be done. This problem however, is driving me nuts. As I said, the only symptoms of the light copies are that add toner light that comes on periodically, and toner absolutely packed into the developer unit entrance such that its spills out when I remove the PCU. One last thing, and this is an when all else fails kind of thing: since the toner bottle is full, I open the front door, and using a channellock, I fix the add toner problem by rapping very lightly on the end of the PCU, and the developer unit! This DOES fix the toner out problem every time, but it does NOT fix the light copies. Simply opening the door, sliding the toner carrier out, putting it back, and then closing the door, and repeating that process a couple of times sometimes also works.
