Problem with 35" Sony TV picture tube

A couple of months ago I noticed a problem with the picture tube. The
picture has a slightly brighter image in a circular pattern running
near the edge of the tube. (This is in a 4-1/2 year old KV-35S42.)

Fortunately I have an extended warranty (from Sears, where I bought the
set), and the service rep said the problem was with the picture tube.
He also said that he could replace the tube, but the replacement would
be a "remanufactured" tube, and because my tube is otherwise fine (good
color, contrast, and clarity) I might wind up with a worse picture tube
than the one I have!

Does this sound like a reasonable warning? The main time you see the
circle (and a slight graying out beyond it) is with bright, light
images, such as pictures of a light blue or gray sky or similar images.

So, I'd like to know what to expect from a remanufactured tube, and
whether the defect in my tube is likely to get worse over time. Other
comments also welcome.

TIA.

Fred

My Sony had "over-scan", usually at the top and bottom of the screen. Your
description looks like something different. Over-scan was on brand new tubes
and showed up on a black screen with bright white scrolling text.

Rebuilt tubes vary in quality. I had a rebuilt Zenith tube that I swear was
much brighter and overall better performing than a new tube. The rebuilder
had a lot of experience (around 30 years).

sci.electronics.repair would be a better place for this question.

I had a problem with the picture on my 9 year old Sony. I put some photos
up on the web and a very kind soul on the group identified the problem
immediately and told me how to fix it. TV works like new again.

Even if you don't feel up to doing anything yourself, at least you'll get
some constructive suggestions to what might be going on.

(I have included the sci.electronics.repair group on this reply).

Regards,

John.
