If you turn color off and stand back and examine the screen---if it is not black and white but yellow looking you have bad Glycol in the blue picture tube which is quite common.
Easy way to know for sure is with set on and rear cover removed peek with a small mirror at the three lens---don't touch anything with the set on===each tube red,blue, green should have a picture with the set on.
Likely you will find the blue one looks like a floodlight with little or NO image/picture.
its sounds like the convergence on your TV needs to be adjusted. (this adjusts all of the color guns in the back of the tv to line them up again, when they get off, you start to get yellow blue or red halos around objects in the picture. In the setup menu on your TV under picture or Display there will be an item that says "convergence" follow the instructions in there so all the crosses on the screen no longer have colored halos anymore.
ok,,your problem is not on the lamp itself.,the problem is on your screen controller.the controller is connected on the plyback you can adjust the screen intensity of the red,green,blue cathode..on your screen adjustment.
This TV has had a long life. Your picture is looking more yellow these days because the Blue picture tube is wearing out. Not saying the Green and Red tub are much better, but Blue tube is a major player in the picture brightness and white balance (the color of white which the TV reproduces). The cost involved wouldn't be justified. You should enjoy the balance of the TVs life; when it's time comes... have the new TV delivered and ask them recycle this one. Best wishes.
These procedures are from the owners manual, go into menu and then picture quality and then:
Convergence
The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’
images are precisely aligned, they create the color images you see on the screen.
Over time, the picture can drift out of alignment (this is normal). If your picture
seems fuzzy or has a yellow tint, using Convergence could correct this
misalignment. Only one convergence is needed for all inputs, regardless of the
signal format.
Note: Make sure the TV has been on for at least 30 minutes (TV needs to
warm up for best results) before starting Auto Converge or Red/Blue
Centering.
When you select the Convergence feature, a submenu appears with three options:
Auto Converge Automatically aligns the projection lenses to self-correct
color images. You’ll see flashing squares of color dance across the screen
(this is normal).
Note: After performing auto convergence, use the Blue Centering and
Red Centering menus to fine tune convergence in the center of the
screen, if necessary.
Blue Centering Aligns the blue and green images to fine-tune the picture.
Red Centering Aligns the red and green images to fine-tune the picture.
Note: The ability to change channels is disabled when adjusting the
convergence options. The TV must be tuned to a usable signal to
converge the picture.
Hi the green cross it cant move that the reference for red and blue adjustement ;just try to put the red and blue cross over the green pattern then quit/
if that doesnt work you probly have the stk-xxx ic
who control the color alignment ,are blow/
you will have to replaced and make the convergence
check if you have an auto adjustement for that most projection tv have one...
hope that help..
try to set the convergance if you cant you can adjust the color tubes from inside the tv but have to be very careful to do this. There is actually only 3 colors in the tv red, blue green so I would say your blue and green need lined up
Go into the menu and look for Screen Convergence. It may also have an auto convergance option try that first. If it gives a suto error or you cant adjust it manually the convergance IC's may be bad or a component on the convergance board.
