Hi All, I have a Sharp 20am100 here that has a 3 to 4" blank space at the top of the screen with the same in fold over. Have changed all caps in the vertical deflection circuit with no improvement. checked for 24.7 on pin# 3 and #6 of IC501 and only have 20.5V and 19.4V any help please. Note IC501 seems to go into thermal run away.
