Question about Hitachi 43FWX20B 43" Rear Projection Television
Overnight this problem appeared. All shapes on the right hand side of the screen have a red shadow to the right and figures on the left hand side of the screen have a red shadow to their left. As the news ticker goes across the bottom of the screen a red copy of all letters appears to curve outwards from the background into the screen and follow the letters, gradually matching up and aligning properly in the middle of the screen, then the red copy letters gradually seem to fall back from the screen and curve back into the depths as if the red were on a circular screen that exists behind the real screen. What repair will this need. I know this is confusing, but the problem does not exist in the middle of the screen, just on the outer 1/3s of the screen. What controls and aligns the red in this thing? Any thoughts and help will be greatly appreciated. Bob W.
1) Whenever a rear projection TV has convergence issues, the
fix involves replacement of both IC's = STK392-110.......sub to
STK394-160E for improved durability...........
2) Soldering only is a temporary "fix" at best
3) Do not allow generic IC's, OEM quality or better = I use
Hitachi brand,made by Sanyo,with no callbacks....
4) Skill level needed = above average,....needs chassis pull...T.
