    tv has shadows in yellow in blue. Yellow arch on the bottom. Blue at the top. Comcast tv guide when called upon has a shadow of itself above the orginal. Baseball thrown has a yellow or blue shadow depending on where it is at on tv screen.

    tv has yellowis and bluish tones. Yellow resides on the lower half. Blue on the top. Everything has a shadow no matter how dark the picture.



    TRIED: Pushing on the cables to make sure they are in good. Checked the convergence tried different things with that setting. Menu and picture function did nothing for me either.



    I've heard of bulbs going. Is this possibly one of those things. If thats the case am I better off buying a new one.

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;

Sounds like you have bad Convergence Output IC > 267P155010 > STK393-110, replace and it will correct the problem TV uses only ONE, make sure all resistors look good in the circuit around IC.
Good Luck, big IRISH.

Only getting red, yellow, black picture. Like a picture negative....


Good Day, kybryants;
The problem with that TV is normally the STK's IC's, convergence IC's, but you describe something different. So, try these:
1. CHECK FOR OPEN L2C50 PART #325C146030 ON THE SIGNAL PCB.
2. CHECK C2P05 100 UFD 16 V OFF PIN 3 OF IC2P01 AND IC2P01 PART # 270P466020 (9-VOLT REGULATOR). BOTH ARE ON THE SIGNAL PCB.
3. THE CONVERGENCE CAN BE RESET BY PRESSING "MENU 12596" TO ENTER THE CONV MISC. MENU THEN "8970" TO RESET.
Good Luck, big IRISH.

Pictue is dark as hell


use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
