Question about NEC VT460 Multimedia Projector

1 Answer

Blub brightness has dimmed.

The projector has 87% bulb life left, however it is so dim that you can barely read the screen. The various brightness sections in the projector menu don't make a big enough differance. Another projector with the same usage is signifcantly brighter.

Hello
Check the intensity of ligh that emits from the lamp. If it is very weak that noral as it should be, the fault you describe here will occur. If it seems to be very dim, we have to suspect its inverter secion, which supply voltage to the bulb. Actually this is a ver skilled job and should be done by any experienced service technician or by the authorised service center for Epson at your town. OK.

Hitachi 50V710 The picture is dim, then the bulb went out. I replaced the bulb. all works but the picture is still dim. You can barely see the screen durring the day. And can only use it in a dark room...


I've seen this in two scenarios.


First: The housing of the bulb is dirty (the lens the bulb lights onto) and the internal screen is dirty also.


The second: The bulb is wired reversely of the proper way to wire it. This will light the bulb, but will not light as bright as when it is wired correctly!


Thank you and please rate!

The image is very dim, even on maximum brightness. We are considering replacing the bulb, but bulbs for this projector are very expensive and we suspect that since there is some image, the bulb is not the...


Yes, as bulbs age they will begin losing brightness. Most projectors have a bulb life hour clock, that measures the number of hours a bulb has been used. Usually you can pull that up within the menu of the projector. Also that particular model has what is called "Eco-Mode" and when engaged dims the bulb by 25% to cut down on power consumption.

Typical life for a lamp in that projector is:

3000 hours on Normal mode
6000 hours on Eco mode

You can expect a brightness loss of 50% when you are approaching end of a lamps life.

How can i fix the brightnees in my 61md10


there is a menu setting for best pix or longer lamp life.
Also, turn up brightness of picture settings(different menu)
Also use daylight setting, vibrant, (different menu).
Bulbs dim over time and dust can accumulate on projector lens, mirrors and (not so much on mine) back of screen.
New lamps tend to melt a plastic lens in light engine, a dark shadow may start to appear upper left or center. this started to happen to me with new bulb, (Ebay O.E.M. supposedly $114). I switched back to original lamp hopefully to slow the burn till I can tacklle a repair. Take a look at this website. Hope that helps.

What is the lamp life on a sanyo plv-z2 bulb and how to read the bulb life there are 3 numbers that come up when i check it


If I remember correctly, you hold down either the power or the menu button for 30 seconds... I believe it is the power button, and it will briefly display it on the screen, but this assumes it was reset at the time the lamp was installed. The counter counts up on this model, and the lamp replace light will come on at 3000 hours. I have 2 of these units, and I have gotten at least 5000 hours out of each lamp. Toward the end of the lamp life, it may start getting dim and/or have difficulty starting, but I probably wouldn't replace it until you either notice the dimming or the lamp fails, although I've heard some say they can damage the projector when they fail, I have not had any problems.

Image is dim. How do I adjust brightness


You can adjust the brightness through the user menu, under the picture option. You might want to look at your bulb. It might be time to replace the lamp.

Is there any way to check the bulb life on a Sanyo PLC-XU30 projector? I know some projectors have an option on the menu screen which lets you know how long the bulb has left. Its just that i bought it off...


on my XU 55 the trick to read the lamp hours is to press and hold down the power button in about 20 seconds when the projector is turned on. there will come a window in the upper left corner that tells about total hours and lamp hours. the window will disappear quite fast, so one might need to do it twice.
