Hi All, I have recently restored a Nintendo VS Uni-system cab and am having a slight issue with the monitor. For reference the monitor is in horizontally and I am getting a random shaking of the picture up and down. Here is what I have done so far:

- Checked B+ (It is running at a solid 108.3v)
- Adjusted all my pots, colours are all looking good now.
- Degaused it with a wand which helped fix the colour even more.

Now I must declare I am running this in Australia where we are on 240v. I put a switching PSU in this cab along with a step down isolation transformer for the monitor. This however out puts between 112v and 113v when measured on my multi meter. Do you think this is too high? Could it be causing the shaking as I read that these should run at 100v ?

Any suggestions would be appreciated.
 
did you do a cap kit and reflow on your restoration??
 
just do the capkit :)

is it a pain? yes

are your first couple a little scary/intimidating? they were for me at least lol (I have zero electronics work background)

but these days I just re-cap them (even on 20-EZs that have already been re-capped) as I put them in working games (regardless of condition). it's a bit grueling, but it eliminates so many troubleshooting steps/problems both in the present and the future.

after a fresh re-cap (and a good tuning), 20-EZs look so fk'n crisp and vibrant.

good luck man!

Not yet.. I was hoping to avoid it but looks like it is on the cards..

Sanyos are an easy cap kit job. Very well labeled and nice strong enough joints. Only issue is disassembly.
 
agreed.

for anyone new to capkits, I'd just say take a TON of pics before and during disassembly and have a couple component maps handy (there's a bunch of folks hosting them online) of the chassis ... will help you track down those caps that you just can't seem to find when re-capping the thing

if you take your time, remain organized, and take notes as you replace components, a re-cap is within the technical capabilities of anyone here at KLOV

ALSO DISCHARGE IT SAFELY! Sanyo's dont discharge themselves and pack a mean punch. Forgot that stay safe op :) also 112 is a little high, they're really supposed to be 110 max but 100 or lower is really better try and get it lower
 
Thanks all for the suggestions. I have done a cap kit before on another chassis so not worried about the technical aspect it was just I was trying to avoid it due to time constraints.

Anyway I will likely grab a kit and try it in the next week or so.

Cheers
