Question about Hitachi UltraVision CineForm 55VG825 55" HDTV

Open Question

Blurry picture, letters have a "shadow" of themselves

Any words that show up on the screen have a shadow effect. For example, when the ABC logo shows up at the corner of the screen when I'm watching the basketball finals, it looks like there is another, fainter, logo behind it. 
The picture itself isn't terrible, just a little blurry. I'm thinking it might be a problem with the lamp(s)?

your convergance amplifiers have gone bad they are stk392-110 but you can replace them with stk392-120 there are two of them in the circuit. there may be some support resistors that have gone bad I'm including a link to a service manual. if you don't have the ablity to do this repair leave it to tthe pros.

stk 392-110 ic's on convergence board are likely problem.

SOURCE: Blue shadows appear to be behind white objects

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.

This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!
