My picture appears to be getting darker and darker.

Many of these DLP sets the picture gets darker right before the lamp fails.

Average life of the lamp is 2,000 hours----about 1 to 2 years of normal use.

If the lamp has not been replaced for a long time it is first suspect in this case.

Let me know if you have questions.

If the pictures of a TV appear to be darker than they are used to be the first thing which should be checked are the brightness and contrast button. Check for them and increse either one or both of them to brighten your picture.
Hope this solution has been helpfulo?

I have a PT61SX60 forsale. It works too. Anyone want it?

You are correct in assuming this is a shutter problem. Your camera needs service.

replace the coolant in the CRTs that will restore the color and brightness to a new appearance. You can get the coolant replacement kit at the following link.

I would need more information as to how fast the picture is getting darker. If it is happens over a matter of hours as you watch it the tv may have a lamp driver issue and requires service. If it has been getting darker over a period of months, you may need a new lamp.

The Digimax A7 Doesn't work outdoors, because on top of the camera, try taking a picture, but hold your hand on the top of your camera (Cover it) it's light sensitive. On top their is a built in sensor, the Darker it is the darker the picture is, the lighter, the lighter. If you cover it, (Usually on top) It should work fine outdoor, just don' t cover it indoor. Hope this helped. -CA

Hi,

If the Lamp condition is okay then check the FE lens just next to the lamp in the projector after removing the lamp out of prj. replace if that is burnt.otherwise replace Lamp.
