Projection TV when turned on picture is dark can view slight images until dinning room light is turned on
When turning on my Mitsubishi Projection TV the picture is dark and can see slight images. But when turning on light switch for dinning room lights in adjacent room the picture brightens to normal viewing, when turning of dinning room light picture goes dark again.
The electrical outlet for the TV is separate from the dinning room lights

Try hooking the TV to a different outlet fed by a different breaker. Does the problem go away? If so, the culprit may be a wiring problem in your house that is causing the TV not to get enough power unless the dining room light is on.If in doubt, consult an electrician to make sure both the dining room light and TV outlet circuits are working properly.

Since not a brand or model number listed : If its a LCD set get a flashlight and make the room very dark with the set on. Shine the light on the screen at an angle to see if you see a faint image of the picture on the screen.
It sounds like you TV is overheating and the video is suffering and the lamp is overheating as well. Also, if your TV is over 2-3 years old, the mirrors (behind and below the big front screen) desperately need to be cleaned. Clean all filters and fans as well. (Look on side and behind the unit). Is the TV in a "hot" environment and/or dirty environment? DLP TV's are NOT sealed units. They need to be cleaned every few years to work well to have a good, clear, bright picture.
Go into the tv menu and select the Preferences menu and set your picutre preference from Theater to Normal. The TV is currently in Theater mode, wich is for viewing with no lights on in the room. Switching it to normal lightens the pictue a lot.
If the tv looks now dark this is the first symptom of a lamp replacement (refer to the user's manual to do this job) and get a Mitsubishi original replacement.
the best picture setting (when the lamp is back of course) depends in the light of the room.
Now if after replacing de lamp and playing with the settings and the screen still pale, dimm, not enought color. a cleanning in the reflexion area is needed. (technican job)
turn down the red screen control slightly the box is located behind the grille 6 knobs on it look carefully for the screen making on it for red do not adjust any other control best done in a dark room with no source in a video input if the tv will not auto align you have the control backed off to far
it could be as simple as the tv feeding back on itself in a dark room. it is adjusting the light level because of what it sees ambient in the room. turn on a light near the tv and see if it stays constant now.
Does the TV have a light sensor? If so, turn it off. The light sensor limits the backlights intensity at night or when it's dark in your room in order for better vieweing convenience.
If you are in a dark environment, it really pains your eyes when the view is too bright. Same works the other way around. If it's day, and light in your room. The light sensor will dimm the backlight for it isn't needed.
