Dark picture on Projection TV

I have a 50" Philips projection TV. The picture on the TV has gotten progressively darker. I've turned the brightness all the way to 100 with no improvement. The picture is clear, just dark and very hard to see.

I've read other posts about cleaning the bulbs, would this help with my situation?

Thanks

I would think...

it wouldn't hurt. If not the bulb, cleaning the lens should definitely help.

Get a new lamp

They do not last for ever, any where from 2,000 to 8,000 hours depending tv brand & model #.
About how many hours are on yours?
& what is the lamps rated life? Sometimes they do not last the rated life for a few reasons, sometimes they last more, I have around 10,000-12,000 hours on a 8,000 hours rated lamp.


The lamp is in a sealed (should be, my Sony SXRD lamp is) compartment. Pull the lamp is check for dust, do NOT use any water, window clear or anything like that on the bulb!!! Use a dry very soft cloth & use your vacuum cleaner, DO NOT TOUCH the bulb with your bear hands, the oils on your hands can do damage. Also check the lamp for color distortion, it will either be a black ring/spot or look like a rainbow that is a bad/old bulb.

I am 99% sure you just need a new lamp.

Oh &

The brightness setting does nothing to the brightness of the overall screen, that deals with the brightness of the blacks & shadow detail, so turn that back down to around the 50's. You what to turn up the "contrast" setting that will make the overall screen brighter, if it is still dim & if your tv has an auto iris turn that up too the highest setting to get more life out of the lamp.
