Cleaning the mirrors will not increase the brightness much. I would double check the lamp setting in the Menu and also the setting of the picture and brightness settings. Many times these are adjustable independently for different inputs. Besides this, I would look at the Ballast and or the Power Supply to cause the problem. I would recommend a professional to look at it if it is not correctable from the Main Menu of the set.
Hope this helps,

as i previously posted, my picture was dim, muddy looking after replacing lamp with osram lamp. i fixed mine by taking the screen off and cleaning the small mirror. it had a thick layer of dust on it, cleaned with a microfiber cloth. no water, no glass cleaners. i also used a very fine new small paint brush and dusted the projector lens which also had a dust film. brightness, contrast and clarity returned!
