Re: adjustment

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

you cleaned the reflector glass, then tried to make the manual adjustment of the color to have good convergence. you can do the adjustment in the menu set up. if can not get with adjustment, their might be a problem in the convergence circuit board.a bad convergence ic or resistor.

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

If the picture is replace the lamp. Lamp only affects brightness if the color is wacked replace the light engine.

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.
