Like mentioned earlier, look for another 1uf. There are 2 identical 1uf or
2.2uf caps used (depending on model), one is near the vertical output IC, the
other is close to the larger osc/video jungle IC. Look at the color and
size/shape of the original and compare with other C300 series in the set until
you find it's matching cap.
Funny thing is these caps normally check OK on both an ESR meter as well as a
cap checker, but cause linierity problems. You need to replace them both.
