C614 will only solve the bowing problem at the right, not the line at the bottom. Also, if you're working on a 4600 and you need to replace a cap... do not pass go, do not collect 200 microfarads - replace all of them. You don't want to pull that chassis out any more than you have to.
Do the usual, replace all the caps, reflow daughtercard pins on both the main chassis and the daughtercards, and go over everything for cracked solder joints. Then tweak and adjust for best picture. You may have to adjust the horizontal frequency a bit to straighten the image out.
