Default Sony TV KV-32XBR95S,horizontal light bands

Yes use the ESR meter...also look for swollen caps
in the power sections and around the flyback area.
Caps are cheap ....Go to it.

Any suggestions on which filter caps are suspect in this case? Can I test
them with a cap ESR meter that I have?

That Model is know for many bad filter caps
and a mulitude of bad solder joints .
A heavy weight set worth fixing.

James,
Thanks for your quick response. I should point out that the banding
seems to be a function of the horizontal scan lines being either widely
separated or closer together--you can actually see the difference in the
width between the scanning lines as opposed to normal where you can not
easily see the scan lines. That's why I thought it was associated with
vertical scan signal rather than a video problem.

My sony XBR is quite old (92 vintage) but still love the great
picture. Recently it developed the problem of horizontal bands of
light and dark across the entire screen which only appear in light
scenes. If the picture is dark, there are no bands and the intensity
or how visible the bands are is in direct proportion to how bright the
picture is. It appears that the bands are a distortion in the vertical
sync. Thought it could be a power supply related problem because of
the sensitivity to brightness level. I do have the service manual for
the TV. Any suggestions on where to start looking would be greatly
appreciated.

Thanks in advance,
Dan


Sounds like a classic case of jailbars, find the capacitor that filters
the B+ to the video amp, usually it's a 250v lytic on the neck board
but I haven't had that symptom on a Sony so it may be elsewhere.
