Re: Promima pro av 9400+ light dims slightly

It may sound like the bulb needs replacing but first you should make sure that the outlet you plug it into has a constant 110 voltage. You may need to buy a voltage regulator to see if that works first. You can try a new outlet too. Sometimes other sources draw electricity from your wall outlet which cause the drop in voltage and poor lighting. Of coarse if that does not work, replacing the bulb would be the next logical solution. If your handy at opening it up, you could test the capacitors and connections for polarity and resistance with an ohm meter. Also check the current in the wall socket for constant voltage.

I am told the light is very dim. Is this a sign the lamp is going bad?

From the first moment it is used, the lamp in a projector is losing lumens (a measure of light). Most projectors' lamps are good for 1500 to 2000 hours of use. Even at the halfway point, a significant dimming can be noticed.

If you do not have many hours on the lamp, you may have a defective lamp and should seek some sort of compensation from Mitsubishi or whatever retailer you purchased the projector.

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.

Does a bulb go dim slowly or stop working all at once?

It can do both, most of the time though you will find that it just goes out completely when it goes. However there are bulbs that just start to dim, it's impossible to predict which it will do, it is random really. If you have more questions please just reply here and I will help you more. Also PLEASE rate my answer 4 thumbs up, it's extremely important to me to have 4 thumbs up... I would be forever grateful if you could do this for me. Thank you! Let me know if you have more to ask.

Projector vt676 lamp installation

  • Turn over the projector on a soft surface. Use a phillips head screwdriver to push and realease the tab on the lamp cover. The plate lifts up.
  • Use the screwdriver to loosen the two screws holding the lamp module in place. These screws do not come out.
  • Pull the lamp module completely out of the projector. This is the lamp. You will replace with a new lamp module
  • reverse the process to install.

Canon LV-S1 New bulb but won't power up

Have you cleaned the filters? In this situation, the fan and power shuts down even before the bulb lights up and heats up the unit, but perhaps the unit can detect clogged filters.

You can download the manual here if you don't have one. Instructions for cleaning the filters are on page 37.
