Without more information, assuming its a Halide lamp, and the viewing angle of the TV hasn't also got worse I would say yes and quickly, if the image has degraded badly the lamp is close to failure which could cause further damage.
Although only a guide as some lamps last longer than others you should always keep an eye on the lamp hour counter The manual should tell you how long to expect from a lamp.

First check this points: 1. How old is your TV. 2. How many times you have change your lamp. 3. Any sort of weird sounds on the back of the TV.
If you are having problems whit the brightness of your TV or you are seeing a dimmer picture, you might have to change your lamp or your ballast, if it comes to a point where you do not see any image at all but you still hear a sound, then its definitely the lamp, if you dont see image or hear any sound, you might have problems with your ballast, also when your ballast begins to run out the picture can get dimmer due to it sending less amount of voltage to the lamp, i suggest to check with a tech to confirm it, or get a second opinion. Hope i could be of assistance.
We replaced the lamp on our pr61lcx65 rear projector panasonic tv. We still have colorful spots and now it is getting darker and have yellow on bright picture and red on dark picture running through it. Please help.
DID YOU USE THE FOLLOWING LAMP BP96-00826A (PHILIPS WRITTEN ON THE LAMP)? ALSO PLEASE CHECK THAT THE LAMP IS COMPLETELY SEATED OR IT WILL RESULT IN BRIGHTNESS ISSUES. THERE WAS ONE THAT I REPLACED THE LAMP IN AND I NOTICED THAT THE DIAL OPENING ON THE LAMP HOUSING WAS A BIT SMALL AND WOULD NOT ALLOW THE COMPLETE SEATING OF THE LAMP AND I HAD A DARK PICTURE AS A RESULT. I USED MY CORDLESS DRILL WITH THE PHILIPS HEAD STILL ATTACHED AND REAMED THE HOLE LARGER AND IT SOLVED THE PROBLEM. HOPE THIS HELPS.
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
I just replaced a lamp in a Sony LCD projection that was just over a year old and it was bad. It was a VERY dim picture. You have a DLP but, in either case a dim or dark picture is almost always caused by the lamp.
