Electrohome EXTEL-25 monitor - chassis problems

[witchfinder]

I've got two cabs with these monitors in...

Does anyone know anything about them or have a manual? They have these huge metal casings around them and don't seem to use an isolation transformer...

At the moment only one is running. As you can see from the below pic, there is a bit of magnetization on the picture...

It does have a degauss switch which works, but isn't making any difference. The picture also flickers sometimes. Also the majority of the adjuster pots on the chassis don't seem to have any effect on the image. Is there anything I can do to fix these issues or is it not worth the hassle?

I think they ate actually just cased g02s. They are 25". I had one and sold it to smarty. Be may have more info.

It's a G19. I had a thread about it HERE

My monitor did have a toroidal transformer as you'll see in the photos.

Ah g19. Thanks dude.

Just bumping this thread as I finally did something with
this monitor yesterday. I swapped over the tube from the non-worker to the
chassis that sort of works, and am getting a much less magnetised image.

However, sometimes when I switch it on I get an image like
this:

And sometimes it’s like this – note the collapse/wrapping at the top and the large black blob
on the left hand side!

There is also some flickering at the top of the image.
I've had a bit of a play with some of the pots on the chassis but most of them
don’t seem to do a lot and it doesn't get much better than these two images.

So what’s wrong with it, and is it easy to fix? Bear in
mind I do have a spare chassis (albeit non-working) that I could potentially
pull parts from to try and fix this. If it’s something relatively simple that
can be identified then I may try that, but otherwise does anyone have any
expertise with these chassis that could attempt a repair?

I'd go with a cap kit. I had this similar artifact on a monitor...

...that was cleaned up with a cap kit. The off colour in the corners suggests a degauss issue - either coil is not connected or the degauss circuit may be faulty.
