Thats a very strong possibilty the phosphorus may be burned off the CRT face. Does the blue project when powerd up and looking in from the raer of the set? Look into the blue CRT lens while its playing If you can see a clear picture I would think that you have some open resistors in the blue circuit, If you cant see a picture its time for a CRT. If you need a CRT let me Know I have a good source for them Used.
SOURCE: no blue just red and green tint
adjust the blue bias on the high voltage block .
it has focus and bias for all three colors
SOURCE: the Screen looks 3D & Colors don't line up on my big screen????
If the convergence is off more than 1/2 inch or so you can't adjust. you have a failure of hardware. most likely the output IC. This set has 2 outputs for convergence. Each output contains 3 circuits, Six circuits altogether 2 red ,2 blue and 2 green. The normal customer adjustment will only alow adjustment of blue and red. They should be converged onto the green. There is a much more complex adjustment in the service mode for Geometry and convergence. These adjustments are only needed when you replace a failed componnent like the output ic. These ICs have been upgraded several times since the production of this set. The latest and most powerfull version is STK394-160. If feel up to it I suggest changing both outputs and the corresponding output resistors. Then do a complete geometry and convergence alignment.
SOURCE: the red, green and blue colors do not line up correctly
This set is fairly easy to fix for this trouble. A AV48p30 usually takes me about 40 minutes to fix for this problem.
It uses two of the STK-392-110 convergence chips. The repair involves two things--getting at the chips (easy) and being able to unsolder them and replace them.
You can buy almost everything you will need on Ebay for under 30 dollars (I can tell you who to look for there)
Most shops are going to get 300 or more for this kind of repair so if you or someone you know can do it you can save a lot of money.
I can tell you how to get at the chips and also everything you will need to do the repair.

I will need the model number of your set to be able to assist you with the problem.
Testimonial: "Very helpful. Great to have someone that is willing to share skills. Appreciate the time taken to help. Thanks"
Look through your manual. Your manual will always give you the most specific directions for your particular model. Look for an "adjusting convergence" or "set manual convergence" section.
