Blue (actual) lamp out of focus. Picture is washed out and milky.
Was given a Philips 9P6034C 60 in. It has a great picture other than the washed out look. It converges nicely and is sharp and clear on, for instance, face close ups where bright or white images are not in the pic.
I decided to investigate and whipped the front off and gave the mirror a good clean. Then I noticed what the problem was:
When I look directly into the colored lamps,the green and red have a super crisp, clear and sharp picture, but the blue one, although it has a picture, is very faded and faint. It's there , but with no sharpness at all.
Can someone please tell me what this means and perhaps how to fix it.
Again - it is not covergence - Actually physically looking directly into the lamp shows that it is not in sharp focus, yet the green and red are.
Thanks in advance.

The curving is caused by bad digital convergencr chips (2) located on large signal board. They need replaced along with blown pico fuses and the convergence resistors. Chips are huge compared to a regular IC. 2" x 1.5" and they will be bolted on fairly large heatsinks. Cloudy picture is most likely the coolant needs replaced in the picture tubes. This needs to be done approximately every 5 years.
sorry but those adjustment are not the right one , to correct the color problem u have frist , u need to hire a tv tech , tv would has to adjust the screen and focus back to normal after that , need to replace the oil on green and blue picture tube
yes! those are the screen and focus adjustments. 3 for screen, 3 for focus. try this. go in menu....turn down color, brightness, contrast all they way down. you should then have no picture, but in your case a little red. then go to back of tv and turn those 3 screen adjustments all the way down. slowly turn the screens back up until you get barely a picture. because remember, your brightness and contrast is all the way down. the picture should be dim but seeable and with red, green, blue adjustments, make it a black and white picture. when balanced..... turn up color , brightness, contrast in menu. enjoy!
If you have not already done so go into the picture menu and set the convergence. The convergence is the angle at which the three picture tubes meat at a given distance. The tv will have at least 3 and up to 64 convergence points, and those 64 can be set for all three colors. This can be tiresome but I'll be it will solve your problem. What your trying to do is get the color in the cross-hair so you cannot see the color behind the target. On top of the fine setting for each point and color you will probably have 3 gross adujustments for blue and green and maybe red. These adjustments will affect positioning, like what you are discribing. You should do this at least every month, the thermal cycleing of the lamps is what will cause this to creep out of adjustment.
