what video symptoms do cap kits resolve

[vintagegamer]

Having some vid issues with my Qbert when it first powers up, so I'm trying to find out what problems cap kits will fix..  any input would be greatly appreciated.

Cap kits can solve countless issues. It can be as little as cleaning up a little wave in your picture to as major as bringing a black screen back to life. If those capacitors are all dried out and not functioning, all sorts of issues can crop up.

Cap kits? What is it and where can I get them? I assume cap means capacitors.

[vintagegamer]

That's correct FJL-  cap is short for capacitors and you can buy them online..

Jeff: that's a pretty significant difference!  I'm just wondering however if cap kits also resolve vid adjustment issues (ie it requires some horiz or vert adjustment b/c it will either roll from left to right slowly or things like that)- I'm having that problem with my Q*bert..  once adjusted it's fine until the next time you shut it off.  (I know, everyone's probably saying JUST LEAVE IT ON THEN!!)

Is it the original monitor ? Then it's about 25 years old, and so you should re-cap it anyway.

I actually don't really like the name cap-kit, because it's only a certain kind of capacitors that are drying out, namely electrolytic capacitors. The stuff inside is a gel/liquid kind of stuff, tightly rolled in aluminium foil.

Anyway, if you order a cap-kit you usually only receive electrolytic capacitors (we call them elco's here to differ them from regular caps).

Maybe the better questions is "What video symptoms DON'T cap kits resolve".

I've been practicing my soldering working up to doing my first cap kit. I was a little intimidated that my first cap kit was for my Neotec 2515c (33 caps IIRC). I now have a WG K7100 that's going to be "my first".

Doesn't look worth it to me.

I have not bought a capkit through arcadehop yet. Zanen is great, but DO check the values of the caps. They should be equal to or GREATER than the originals ! The WG K4500 kit I received had a wrong value and really messed up the picture. Also beware that capkits do not correct convergence problems (that is, the color beams ligning up). Convergence is a nighmare to correct and I wouldn't bother with a 25 year old monitor....

Cap kits? I don't need no stinking cap kits!

Ok, who knows what movie that is originally from (kinda)?
