We have a 41 in Samsung DLP hdtv- the screen seems to be fuzzy- the lamp warning lights have not indicated that it is time to replace the lamp- could it be from dust getting into the set?

The screen on my Samsung DLP tv turned off with the volume still playing. The lamp light started flashing. We replaced the lamp and it doesn't seem to have fixed anything. What could be wrong?

Lamp Fan could be defective or the Ballast Board ,it is what powers Lamp.

Is it possible that dust or age has hazed the lamp and or mirrors and cleaning would improve the picture?

Well, yes. Dust blocks light and will tend to make the image fuzzy if there is buildup. If you clean the optics or anything, Do NOT touch the lamp. Oil or other things will weaken the Quartz and it will burn out very quickly. If you do accidentally touch the lamp, wipe it thoroughly with rubbing alcohol and allow to dry. Follow any cleaning instructions that may be listed in the manual

Mitsubishi 65in DLP TV picture is not clear after I replaced the bulb. It was clear before the bulb was replaced but it seems to take time to catch up and is a little fuzzy.

Sometimes dust can get in between the lamp and lens take lamp out and check for dust with a lint free cloth.
If thats not it it could be the manufacturer of the lamp. I usually try to get the same manufacturer. You can try tinkering with sharpness or contrast but remember the points you adjust from just in case it makes it worst.
Good luck

Mitsubishi WD-52525 52-inch DLP HDTV ywllow warning lamp light

that means your lamp it is getting to the end of its life.
sometimes even if the lamp still good the TV will send you that message because that timer is closed to 5000 hours

What you can do is open the lamp door, closed again and the tv will ask you if you replaced it the lamp, and just say yes and that sign will go away

or just simple replace the lamp. 915P020010
