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.

Good Day, sh28;
Sounds like bad convergence IC’s, chips. Hit recommends using STK392-150’s and replacing the bias resistors.
Good Luck, Big Irish.

Problem continued

Good Day;

When you activate the Mj focus the TV is restoring the data from the TV's digital circuits. So, you have the ability to change the IC's you can do this.

You need to go into the con service mode. Take off the front grill, remove panel, 6 - 8 screws. From the front there is a switch on the left hand side, it is small, white button with TV on. now you are in the service mode, using TV's remote adjust. Make sure you save dat. Go hit on line site get more info.

Goo0d Luck!

Double shadow green and pourple

check the 3.3ohm resistors right next to the convergence ICs. Also the ICs for 3.49 are most likely cheap chinese ICs and not origional sanyo ICs . I have seen the cheap ICs go out as soon as you power up the set the first time.If you need more assistance please let me know.

Green shadows all over the screen

You didn't say how old the set was and how much it's used, but the shadows you're describing sound like a bad green picture tube.

Hope that helps...
