Color shadowing on screen


I had similar symptoms about a year ago. Also came on sudden. The red convergence chip had burned out (poor heat sinking on this model Hitachi). Replacing the color convergence chips fixed it. ($50 for parts.) First, however, have you tried the "magic focus" function? That's explained in the manual, which is available online IIRC, but I'd have to look for the link if you need it.

Problems with my Mitsubishi hd1080


If the Blue lines are blurs or shadows, then your Convergence IC's are going or gone bad.
I have the same TV - it will be 4yrs. old in Dec. Mine started with Blue lines & shadows, then Red, Blue, Green Shadows. This is caused from over heating. The Convergence IC's have to be replaced.
I have had 3 TV Repair shops all quote me a price from $350. to $400. to repair. They all said 4 years is the usual life time for these IC's.
Replace the STK932-110amps with STK394-250-E or STK392-150 for greater reliability.
Use only Original Replacement Parts, there are some cheaper but won't last and can't take the heat.
If you are a "do-it-yourselfer" here is a link with the directions and pics.

Sony tv KP-61HS10 lenses wont align


This is common in those sets. One of your convergence IC's has stopped working and needs to be replaced. The convergence IC should be replaced and the convergence circuits realigned by someone with experience in Sony projection sets.
