Lamp problems? I have owned this tv for 2 years now.  I have replaced the bulb once, and the new bulb is only 6 mos. old.  The picture is very dark.  I have the brightness and contrast settings all the way up and still have difficulty seeing a good picture. What do you think could be the issue?  Is the bulb bad again?

Test the voltage to the bulbs and see if it meets specs. May be a power supply problem.

Sounds like lamp again-- dark pic. Get quality lamp, need 4 inch space all around TV for cooling. Maybe cleanout dust inside.

Google the model number to locate it with "lamp" and You Tube has video instructions for replacing in most models--lamp has a 2,000 hour or 2 year average life and is meant to be replaceable by the customer who owns the set.

most likely optical engine issue----bad light engine.

its probably the lamp going bad. dark picture is a pre-cursor to failure. these lamps are supposed to last 2-4 years but for some reason the mitsubishi ones never do. you can replace the lamp yourself, and if it is going bad, you can cool it down, pull it out, and you will see it will look kind of bulged or white in the bulb part. instructions are in your user manual. if it is under a year old, mitsubishi should still cover it. if its just over a year, you can try to call them and complain and maybe they'll back it up. let me know if you need further assistance.

bulb should last longer than 6 mo. could be a problem with the Ballast or the power supply board.

I have the same problem, TV is only 3 years old. Already replace bulb once and helped for a little while. The more I check, this sounds like a very common problem. Hmm...maybe a class action suit?

did you change the lamp with an original or bulb only - mitsubishi only sells the lamp and housing!!!
never use generic

Do you have your TV plugged directly into the wall? You cannot plug into a power strip, it needs its own direct power source. Also, I have heard that there can be electrical problems inside. I have this same model, I love it, picture and sound. I just replaced the bulb for the first time last night. It was a little premature to replace it now but I know what caused it. I bought a new bulb and it works like a gem. If you ever need to change the bulb do it yourself. It takes maybe 2 minutes. The bulb looks like the Flux Copassitor and all you do is remove the door in the back on the side. Unscrew the the 2 screws that hold the bulb in and just pull out. When you put the new one in make sure you do NOT touch the glass on the new lamp. Just slid it in and screw the 2 screws back in and make sure the door is closed and tight. My uncle had a service guy do his and he got raked for 5-$600, The bulb costs about $200. Should last about 5-6 years at a rate of 5-6 hours of TV on time. Hope this helped. If not, sorry, but at least you know how to change the bulb. Good Luck!!!

I have the same issues with my Westinghouse LCD set. I've found that going into the settings (using the TV remote) I can get it back to a bright picture by selecting 'restore factory settings'. It is aggravating and a pain, but I can correct it.

It only seems to do it on the analog stations, not the digital (HD) ones, so maybe it will go away after the conversion next year.

Hope this works for you.
