1977 Zenith Chromacolor II Space Command

[maxm]

This set is a recent estate sale find. It was in a finished basement and is in pretty nice condition. It included the remote control, though the remote will need a new battery connector because of corrosion. Model SJ1939W, chassis 19JC60Z.

After running for about 30 seconds the picture began to get washed out, then the black electrolytic capacitor on the horizontal chassis in the photo (10uF, 350V) failed by venting a cloud of smoke. Should I change the capacitor and try again, or would this sudden failure be a sign of another problem?

Also, the large oil capacitor on the chassis is starting to leak and I would like to replace it (3.5uF, 440V AC). Would one like this work instead?
