If the picture is dim with no distortion then replace the lamp.Usually when the lamp is used for around 2 years it starts to have dim picture before it stops working or breaks inside.

Projection tv lamps


All fillament based lights will dim as they age. Some of the newer/better types it will be unnoticible.  If you are losing image quality or brightness you may have a bulb that is nearing the end of it's life cycle.  A glance at you owners manual or the manufactor's website should give you an indication of the expected life of your bulb.  Also most of the projector made in the past few years have a counter that tallies the amount of hours your bulb has been on.  A more likely culprit is probably dust accumilation somewhere inside your projector. Most projectors have filters these days and need to cleaned at certain intervals and in certains ways.  Not cleaning these filters can cause heat build up that can increase operating temps and shorten the life of your bulb and or projector.  Or sometimes jsut fail and cause a dramatic decrease in image quality.  Again these things are vendor/model specific so you will want to check with them about your particular model. Hope this helps.
