Hitachi 51swx20b, turned set on one morning,red blue and green were way off, so I manuly adjusted red and blue on crosshatch pattern to match green which is non ajustable, the green lines are concave at bottom and the same at top, from what I read in forums I thought I would try replacing the two chips Stk392-110, didn't fix problem where do I go next Thank You

Carefully observe/check the flameproof low value 1/2 and 1 watt resisitors that are VERY close physically to the STK's. You will find that one of them is open.
