Hi,

I got a TV from somebody, a Sony KV-32WS3D (chassis AE-3)
The upper corners are very colored, see this picture from a teletext
page which should only contain the colors white and blue:

I checked the degauss coils: OK, PTC also OK, the degauss sound can be
heard when the unit is switched on
The deflection yoke was a little bit loose, when I moved it on the
neck of the CRT the colors on the screen are changing but I cannot
get the right colors in the upper corners, in every position of the
yoke, very strange....
There are no magnets from e.g. speakers in the neighbourhood.
The support rubbers for the yoke are still in place except one. But in
every position of the yoke there are colored upper corners....

There are more coils around the CRT: rotation coil. After
disconnecting this one, still bad colors
Another coil is connected to a small PCB at the right side of the
chassis.
Near the connector I read: CY+ and CY- Is this a convergence coil?

Convergence is still OK, only that colored corners...
(oh yes, sometimes several channels are not showing picture, only snow
or a snowy picture)
After a while the picture comes back. I think a bad contact inside the
tuner....)

I cannot believe there is something wrong with the CRT itself.....

Regards,

Arjan
