This 52" PROJO had horizontal lines in picture, with tearing at the
sides.  There was also a small 'horizontal' noise when the lines were
present.  I followed the noise to the deflection board and found black
liquid goop on the solder side underneath C4807.  I went to the
component side and found C4807, a yellow .22M100 capacitor, held on by
only one leg.  The other leg had been eaten away by the black goop,
which I am guessing was silicone used to keep C4807 from vibrating.  I
cleaned up the board and replaced C4807 (no silicone this time) and now
there are no more lines or noise.
