I have small blue dots and a yellow shadow in the middle of my screen


The model indicated uses what is called a Optical Light Engine, it is a very expensive part and likely is your problem---not much else will cause this trouble.

Let me know if you have questions.

Convergence problems.


Your convergence ICs are likely bad, not typically a CRT or tube going out. A repair shop will fix for $200-400 or if you are very skilled you could repair yourself.

It sounds like you have a warped shadow mask in your picture tube if your set uses a picture tube. A shadow mask is like a screen wire that lets the three color guns shoot electrons to their respective phosphor dot on the screen to produce the three primary colors which are mixed properly to produce the scene that is being shown. In other words you have a bad picture tube. Stargazer

Blue and red shadows on screen


This sounds like one of the convergence IC's has cracked loose or burned out, and should be replaced and realigned by someone with experience.
