I have looked and looked and looked and still can't find anywhere that tells me how to fix the width problem on my Sanyo EZ20 - running DK and/or DK Jr.

I have about 1.5" missing from top and bottom, seriously losing a lot of screen.

I've re-capped, checked b+ and tried adjusting the width coil - to no avail.

Someone must have screwed this problem down?
 
some Sanyo's are like that from the factory.

they were common in the VS and Playchoice machines.

C470 is the width cap as far as i know.

decrease the uf value to widen the width.

Buffett before I tear this Sanyo apart for a 7th time, can you tell me the exact value of C470? Can you sell me one of those pillow caps or link me to who sells them? I'm going to take a look at it and see if it is labeled.
Missing about an inch on either side of Warlords cocktail. 14" and can't adjust it out any further.

as i recall c470 is .47uf 200v and i have the complete kits with way more caps and variations and much better caps then BR kits. here is the link to it.

So this is what throws me, this numbering system on these (chicklet/pillow) type caps. The numbering system. Im not comprehending it.

I'm also taking it, that just C470 is responsible for the width alone other than the coil (Meaning it's the only one I need to replace).

bob's kit doesn't have the .39uf 200v cap that you have on that chassis. my kit BTW has the .39uf and many others that BR kit doesn't have.
 
try the f334k cap in that spot.

that will make it wider.
will it be enough?
you will not know until you power up the monitor and see.
you may need to adjust the width coil to fine tune it.

if it is still not wide enough you will have to try another cap and power it up again to see.

changing width caps is a pain on those monitors since they are so confined in the cage.

post pics of your results with the f334k cap.

i have a wide range of width caps i use in my repairs to change the width when i do tube swaps.

All I would say is watch the too much width issue with DK (vertical width when monitor is rotated). DK is meant to have some black around the boarders to allow for that nice "floating" effect. I've seen a few DKs where people go overboard and it just doesn't look right.

The Vs. kit manual talks about switching a DK to a Vs. and the manual clearly says to adjust the width coil (after rotating the monitor) to add width because the vs. games have colored backgrounds that require more width. This indicates that DK and DK Jr. were supposed to have less width.
 
I am going to attempt replacing it with the same only new. I am trusting there is a problem with this width cap. I am thinking a cocktail Warlords should go all the way to the edge of the tube and not have a 1" gap on either side. Although I have seen a few pics of this very problem when googling warlords image.

replacing it with the same value will not make a difference.

if the cap was bad it would be shorted and you would have other issues.

try the value i suggested.

Ok, so I removed the previous cap. Soldered in the F334k in it's place. Powered up. Nothing seems to have changed. I adjusted the HWC until it bottomed out.
I then checked the original cap with the multimeter. .394 right on the nose.

Pretty much out of ideas.

taking the slug OUT or almost out of the width coil will give you the widest pic you can have using the width coil.

screwing it in shrinks the image.

Well now that's odd because I backed it all the way out and it seemed to shink the image. However when I turned to the right, running the slug downward it made it a hair larger. Adjusting the width coil did NOT dramatically change anything.

Now you've got me wondering if I pulled the slug completely out..

This happened on my 4900 WG

At some point it was almost all the way out , the image began to shrink again... I thought I was crazy but it happened.. As I turned back it it began to stretch, but not a lot maybe 1/4 on each side or top to bottom if it's mounted vertically.
 
the width coil has a threshold where the core has an impact on the image one way or the other.

not all are the same.

the K7000 is the way i described, you pull out the core the image is as wide as it will get.

from what i remember the G07 is the same way.

there is also a possibility that on your chassis they the width coil will not have much of an affect at all.

some chassis have a wide adjustment range form the width coil and some do not.

check to see if you have a core in it or not and how long it is if you pull it all the way out.

yes most width coils i have seen if you were to start them all the way in against the pcb and then start backing them out (towards the top) they will hit a narrow to wide twice. in other words if you start unscrewing the ferrite slug you will get narrow and then to its widest point and if you keep unscrewing it goes narrow to wide again or vica versa.
 
Son of a Bitch. I think I see what's going on here. I pulled the core completely out. Got the very same image. Nothing is changing AT ALL. And I think I see why.
