Blue and red shadows on the TV picture

For CRT projection TV's, this indicates that the Green picture tube is burned (warn out). The less green that strikes the screen, the more redish the image will look. You will need to find an old school TV repair shop that knows how to replace picture tubes.
In the case of a DLP style TV, the color wheel needs replacing.

replace stk 392-110 ( or stk 392-150 same number) , check resistor 2.2 ohms for open or burn beside STK IC's

TV will need service soon, blue CRT is on its way out, will need replacing

hello it sound like convergance chips might be the trouble

shaun

TV shows large red spot in middle of tv when dark show are on, you can see it more.  Now blue spots on upper right side too.  Spend way to much on this tv to have these kinds of problems only after 3 yrs.

Sounds like a convergence IC problem, you will need to replace them'

i think you need a new convergence board they rin from about 88.00 to about 140.00

Did you use the Automatica Convergence to try and straighten it out? If that does not help, you can manually adjust the convergence.

might need to get a tech to align it in what is called service mode

your tv needs to be align take it to a tech so that the tv can get a convergence adjustment it is call color bleeding.these things when a set gets old this wil cost between 440.00 TO $75.00,in this the comb filter and the screen voltage will be checked.
