Hi, no adjustment should be needed after a new lamp is installed, if you installed a new lamp and the picture is not correct you have another problem, BMW Rider

When you replaced the lamp, was it doing the same thing? I doubt the lamp was bad, maybe but doubtful. I would try to adjust the color on it. What kind of TV do you have? I need the model and year.

How do I adjust lamp brightnesss for a Viewsonic PJ550 LCD projector?

may be ur projector lamps reflector may be faulty. when it comes to the end of its life. the coting inside th reflector will get bubbled and it will peeled of. that's why the light is very low. u can't increase the brightness of lamp. because it is connected to a well regulated power supply. and the supply voltage is as per the specifications of the lamp. you can adjust the brightness through menu. for that press MENU button and selects PICTURE 1 using down arrow and then press ENTER. select BRIGHTNESS and press ENTER. using up and down arrow adjust the brightness. if still not get the desired brightness lamp should replaced.

Replaced projection lamp because of message on screen to do so. Picture is brighter, but now I have a pinkish margin on top of screen. Is my replacement lamp defective or do I have another problem? Any...

There is no problem. Just adjust the picture by moving it up and down with the help of remote control. It is a small button in the center of top row of buttons ( Left of Green switch on/off button). Then adjusting with the up and down cursor buttons.

Poor quality picture. specifically the red is brown and can't be adjusted. the tv is about 3 years old.

Very dark picture. Video adjustments do not help.

I would check the lamp first. Open the lamp door to see if there is cloudiness near the stem of the lamp. If so, replacing the lamp should make the brightness like when you first bought it.

Recently replaced blown lamp for 50HM67 50 inch tv. Now have picture but clarity is off. Picture / screen words are very blurry. Toshiba referred a local repair company who mentioned that the problem...

If the picture was good before the lamp blew, there might be dust/splatter on the window in front of the lamp. Pull out the lamp assembly and look at the small square glass window that the light shines into. It should be clear and clean. If it is not, clean it gently with isoprophonol alcohol or screen cleaner.
By the way, there is no such thing as convergence adjustment on DLP TVs.

Picture is dark

Adjust video settings:
  1. Press Wega Gate
  2. Select Settings
  3. Highlight Video
  4. Press + to select
  5. Adjust/increase the brightness.
  6. Press Wega gate to exit.
If picture is still dark, you need to replace the lamp again. Sony recommends that you replace the lamp:
  1. After approximately 8,000 hours of use.
  2. When the screen becomes dark or the color becomes unusual.
  3. When the lamp indicator on the front of the TV flashes.
