Early Nintendo Space Firebird 14in "Sanyo in a box"

First KLOV post. Been hanging and leaching for a long time. Just got this old machine up and running. Plays and has a nice picture, however I am unable to get it vertically centered using the pots. It doesn't roll or shake at all. Not sure where to start as I have never had a monitor quite like it. I believe it's an original 100v 14" Sanyo. See pic for what it looks like. Loved to hear any suggesions. Perhaps there is something other than capacitors?

That's actually the horizontal centering, the horizontal is the long dimension and the vertical is the short dimension on these monitors, no matter how it's mounted. So yours is mounted vertically, but since the long axis is what's off, your horizontal centering is off.

I can't remember if on that monitor there's a pot for that, it might be buried in the chassis somewhere which is a paiiiiiiiiiiiin to get to on that particular one.

REALLY fun game, though, and cool cabinet!
 
Thanks for the replies. Yes, sorry, technically it is horizontal. I have adjusted horizontal pots and while they improve image, it still will not completely center. I know some early nintendo machines actually have video adjustment pots on the pcb as well but I couldn't find any on space firebird. I am intrigued by jumpers. Everyone simply recommend caps but I am not confident that would resolve this problem.

caps out of spec can affect alot of things on monitors
 
It looks to wide, and you have curl at the edge so a cap kit may help. Also ther may be some width control that you need to adjust, that might fix the curl.

Here is a video showing me adjusting the horizontal pot. Surely caps may help but I hate shotgunning problems and hoping that will resolve the issue. Not that concerned with curl at the moment, just would like to center the picture. I have a hunch that this may not be a cap causing this. I will likely cap the chassis but again hoping someone here has seen this before.

one thing to keep in mind is you have 30-40 year old caps and they go bad over time even if they aren't used so replacing parts that are of that age i don't feel is shotgunning but its necessary. now if you were replacing a good HOT or other part i would agree with you because they usually either work or don't and you replace them when they fail but not caps, plus caps esr changes and frankly pulling them and testing all of them is a waste of time just replace them all and then you haven't got to worry about them again....(usually);)

BTW: i have the cap kit for it if you need 100% nichicon 105C best quality caps. alot of vendor kits were wrong on this monitor and Zinfer on here had a thread on it, but i made mine from the monitor itself.

I have seen that problem before on other monitors. I agree with Security101 a cap kit might just fix that, and probably the other issues as well.

Btw, are the cap kits for 20EZ similar to these. I have two of those I need to do as well.
 
never worked on a 14" sanyo, I have done 2 20ez's and a cocktail dk jr which has an 18in monitor. One thing I can tell you is be super careful when reinserting the monitor not to neck it. But 20ez's are pretty easy to cap since they're labeled nicely and every sanyo I've come across has needed new caps.
 
Another thing to think about is it could be a sync issue... for instance if you hook up a positive sync monitor with a negative sync board it will sync off screen like that with a line in the middle...

So make sure to replace the caps in the sync section...

nope they are not the same but a 20ez kit (i am not able to look at them side by side at this moment) but from memory is about 2/3 the same cap values but some locations are off.

If you'll link what you think i need for this monitor, as well as a 20 EZ I'll buy parts from ya. Thanks
 
most people don't realize there are two 14inch sanyo chassis the AZZ and the AZW and neither are similar in cap kits. do you know which one you have if not i can figure it out so just PM me.
