Sharp CRT tv flickering on picture not normal

The tv show a wavy kind of picture on screen and only red colour.when its on channel the display will be flickering and unstable.
I opened it up and resolder some dry joints and detect this bulged capacitor of 100v47uf

After replacing with another one of same value I test the tv and it works. The next day the owner brought it back again that the problem still persist. I start to troubleshoot and detect that the 160v100uf filter capacitor is also bad. I changed again and this time the tv works perfectly
