The brightness is very dark. Any nightime scene


Your CRT's getting old. Plus dust on lenses don't help much. You have to open front frill (below screen) and back of the TV. Clean up lenses using dry paper towels, do not wet.
In front of the TV after grill remove center cover and locate "black box" that have 6 potentiometers on it that looks like plastic adjustment screws for philips #2 screwdriver slots. 3 of them should read "Focus" These you don't touch. Another 3 reads "Screen". Put some still image on your screen (like paused DVD movie frame). Carefully add brightness in all 3 colors trying to avoid horizontal lines appearance. If lines show up, just turn it back a little. Try to keep color balance looking at the picture.
This procedure will brighten up image but further reduce CRT's life.

In case that you posted wrong model here and you have DLP Projection TV - just replace the lamp.

Screen getting dark


If you have never changed the lamp this is more than likely the issue, as the tv ages the lamp looses brightness. Most lamps are rated for 3000-5000 hrs of use. Replace the lamp assembly part # UX21514 and you will notice a much brighter picture. You do not mention if the tv plays the right colors on the entire screen. These have had light engine issues.
Good luck with it

Its a slight possibility that a 2.00 Part called a capacitor could be bad on the screen drive voltage source. But most likly it sounds like the Picture tubes are comming to the end of there life expectancy. If the crts are weak there is a crt rejuvinator that could possibly clean the grids off each color gun. But this is a crap shoot, as sometimes it destroys the tubes. These type of repairs are not for the handi-man or a consumer to do. There are no real user replaceable parts inside so unless your able to solder and know the HI Voltage saftey issues, you should call a pro to assist you in this repair. Good Luck
