DIY Cap Kit Question
keefyboy:
Just for reference purposes,
If my arcade monitor's showing symptoms of needing caps replaced, wouldn't it be possible to just examine the caps and replace them with better-spec caps?
I just bought an Atomiswave Japanese cab, and it has a Wei-Ya monitor. It was made in 2003, so it's not *that* old, but 10 years from now, I'd like to still be enjoying it. Unfortunately, no one sells a cap kit for it. Fortunately, I live right next to the electronics capital of the world in Akihabara, so a range of capacitors is readily available. In the US, Mouser Electronics and Newegg is your virtual Akihabara, I just get to see it in-person. :burgerking:
Just figgerin' that if I have a 125V-10uF cap and I replace it with a 250V-20uF cap, it will work. More expensive than necessary, but won't create a black hole that destroys the Universe. :D And in this case, it's a given that we're talking about replacing no-name caps with high-spec ones.
Thanks all! :cheers:

up the voltage rating, but keep the capacitance rating,
i.e to replace a 125V 10uf cap, use a 250v 10uf cap,
only thing to check is if the higher voltage cap will physically fit,

Just want to mention that 2003 is right around that whole "bad cap" scandle that affected pretty much every electronics manufacturer. So it's not too new to have problem caps.
keefyboy:
So what caps do I need to replace? All of them?
That seems unlikely - the few cap kits I saw pictured in no way had every capacitor - just the cylindrical ones, and not very many at that.
I'm going down to Akihabara, and there are a few shops there that sell nothing but caps. No wire, no resistors, no switches, just caps and only caps. I'd like to get a decent DIY cap kit put together so I can replace the caps before everything else gets here. Unfortunately, I have a Wei-Ya M3129D. Unfortunate in that cap kits are unavailable, and recommendations for which caps to replace are non-existent.
I checked the monitor manual, and there's no circuit diagram or cap list.

its the electrolitic capacitors that cause problems,lf you want to be a total pro with the chassis then you remove each cap one at a time and read them with a capacitance meter and then replace as necessary
always try to get 125 degree caps if possible and go for known brands-not some cheap chinese crap
mind you its possible to buy chassis for about 100$
