Wg k7000? Bad focus, or dim picture (solved)
abispac:
Edited to make the topic ore reliable: So this monitor has been caped, inspected for bad traces, and after that it has an ok image, turning focus on flyback all the way up it almost make the image look clear , but turning the brightnes a bit more makes the image look out of focus again.Only way to make the image look good, is by turning brigtnes low and and focus all the way up, it looks good but to dim, or dark. So im getting a flyback to see if thats the problem. Will keep updating this topic. Pardon my bad english and grammar. Im just trying to fix this and hopefully help others that might have the same problem in the future.
So i found a beautiful monitor together with it's base and conections, the screen dont have any burnt in, and the pcb looks decent, a bit dusty but decent, it has like 2 blown caps and a badly burn resistor. I would attempt a cap replacement as the monitor turns on but i get a greenish twisted image, hope the caps would fix it. Ive been trying to id this monitor and it looks alot like a k7000 but it has some small diferences, i couldt find an id number as the only stickers are fade up. Hope someone would help identify this monitor and put it back to life. Thanks for your time and advice.

yep.
these are known for having a few variations as WG started farming out production to a few companies to keep up with demand at the time.
small differences and fixes and revisions and patches between boards here and there but for the most part they are true to schematic for the important bits that break down anyways.

Any advice on something that is a must do while I replace the caps?

Give it a bit of a clean maybe. However, you want to inspect closely for stuff like leaky caps first. You don't want to wash away the evidence before you've seen it.

OOooo... this is really good advice I hadn't heard previously.
