HD34-300 (D34EW11) chassis ATC221, Set has sound but no picture, First thought it could have been the flyback voltage checks good and the adjustment of the screen on the flyback reveals re-trace lines so i'm assuming horizontal and vertical are good, have replaced several caps (raised tops) to no avail, This thing is driving me nuts anyone have any info or suggestions.

Have had other projects going on this ones been on the back burner for a while, anyway the resistor was a 1/4w 4.7 ohm on the CRT board, Replacement brought video back but now set has No Color, In PIP mode the (PIP box) has is in color but the rest remains black and white. I'm guessing it may be another resistor opened up.
