WG25k7000 - Verticaly squeezed in the middle / Streched on top and bottom

[ebo0763]

I have a WG k7000 25" with new cap kit. The image is squeezed in the middle but stretched on top and bottom. So a circle in the top or bottom will actually take the shape of an egg because of the distortion.

I replaced all capacitors (except the very huge one) and I don't know what could cause that.

Any idea?

BTW, the picture doesn't do it justice because the camera was too close and that kind of cancel out the distortion a bit. But it's still noticable.

I'm just thinking... is it possible that the yoke is a bit too close? It seems to me, if it would be further back it would fix it, at least a bit. But I'm very hesitant to play with the yoke. Hope it's something else.

if the yoke has always been in it's present position then I can't see any reason why that would affect the picture.

questions,is that the original tube/yoke combo for that chassis,did the picture display like that before you replaced the caps

It's a not the original chassis, but the chassis that was there before was still a k7000. I just received the monitor recently so I don't really know its full story unfortunatly... I don't know if the yoke and tube are the original combination.

And yes, even before I installed the new caps the image was like that.

its a yoke/chassis mismatch imo

    Well... is there anyway I could test that?

only if you had an original crt/yoke/chassis to compare with

I would suppose you could at least pull the yoke line and measure the resistance and then compare that with a known good one. I'm sure someone here would be able to tell you what the resistance should be.

it is the yoke
wg will confrim it
the part is nla
the yoke will yank out the vert ic in this state
what u want to do is call them and get the vert resistance
find a yoke to match it
is it single/dual freg ?
kv's came both way's
