Capacitors

[TorqueRanger]

I am rebuilding one of my boards and there are really small caps of 10uf -25v/22uf -25 ... I was checking them out today and noticed that alot of them had rusty color residue under each of them and let me guess I have to replace them too because they are leaking ??? If this true them I will be buying over 100 Capacitors for a single t.v.....

Re: Capacitors

If they are leaking then yes. Could you post some pictures? Those caps are really cheap. With the price break on Digi-Key 100 of those sized caps is under $10 before shipping. Time consuming...yes. Expensive? no

Re: Capacitors

Did the board get exposed to a lot of moisture and salty air?

Re: Capacitors

Can you get some more clear pictures? Is there a macro mode?

Re: Capacitors

Is it under every single one of them? If so, it could just be grime deposits. See if there is a similar brown residue on or under anything else that has no electrolyte to leak out.

Re: Capacitors

I can't tell from the pics, is this looking more like brown gunk with dust in it, which probably isn't electrolyte, or more of a crusty lighter colored substance? From what I can see I'd leave the caps in, it's unusual to see ALL of them leaking unless they were all in parallel or complimentary portions of a PSU subcircuit which wouldn't usually use small caps like those.

What was the initial problem with the TV?

Re: Capacitors

They might be leaking, or it might just be leftover flux.

BTW, 'Decon' caps are crap...
