My old "monitor" has a vertical deflection problem. I've noticed one of the caps leaked. (the problem was the top 1/2 stretched, while the bottom shrunk.. until the tube got warm.. but stayed almost the same).
According to the net, it's either Marcom or Elna caps (1uF 50V 105 degrees electrolytic).
So I went and put in there a 1uF 200V 105 degrees electrolytic. Now the picture is shrunk to the middle 1/3 of the screen! :o
These caps are used to drive a AN5521. If I replace the IC, should that fix my problem? are there any equivalent drop in IC's in case I can't find it local to me?
Better yet, what are "low-esr" caps, and how can I tell them when purchasing? Do I have to replace the 2 caps with the exact same "red" caps, or are the ones I put in there now good enough?
Thanks!
