Post the model of the set and the locations of the cap and you might get
more specific help.

You likely have other caps that are bad.

Read the specs to find low esr caps. You will not likely find local
suppliers with a range of options in this area. It is not particularly
critical in most cases, but if you increase the voltage rating it may become
so. A 200V cap will generally have a higher esr than a 50V cap, all else
being equal.

Read the manufacturer's specs to find the esr value.

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!

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!
