red/blue/green lines across top of screen...HUH?
 

Recently purchased a refurbed 34" widescreen CRT from phillips.com. Model is
34PW8402.

OK, so all of a sudden we are seeing three very thin, parallel lines running
horizontally across the screen, about an inch or two from the top. Three
lines, one each in red green and blue. So far we have ONLY noticed these
lines when we use the "Zoom 16:9" mode, which stretches/zooms 16:9 content
to fille the screen, eliminating the letterbox effect. THe lines run
horizontally on the screen, though they are not totally straight, and seem
to "flicker" on and off occassionally...maybe for a minute or two at a time,
then it stops for awhile. (Almost looks like three lines of sideways
lightning. Red, green and blue lightning that is.)

At first I though it was the cables and/or inputs on the TV, but this
happens on two different AV inputs when in the "Zoom 16:9" mode (both the
Playstation2 and the DirecTV box). Both are composite cables. (the cheap
ones, this is strictly a fancy SDTV box for now. No HDMI or Component yet.)

Any ideas on WHAT this may be? I'd like to be able to say I can live with it
and just not use the zoom feature, but that is not gonna happen. :)

Thanks in adavance for your helpful replies.

Sounds like another Sony tube problem..

Even if we correctly identify the problem, what are you going to do
about it?! Still requires service that you can't perform.
Call the dealer, or the nearest authorized repair station.

Why bother replying? I didn't ask what you DON'T know. Thanks though.

The OP was discussing a Philips set, not a Sony. Sony has not had problems
with CRTs in any recent direct view sets that I know of, and we sell a few
and service quite a lot of them.

Could it possibly be not overscanned and what he's seeing is a
calibration for automatic beam? I know commercial Sony units (PVM 14M4
and others) do this when underscanned.

I'd say that is a good guess, and if it was a Sony, it could also be a
service menu setting that moves the IK sample positions. I am not familiar
with the Philips set, however.

The Phillips set uses the Sony tube.

Which set is that? Which tube? Does it use similar AKB circuitry? The IK
sampling, if it is even used has nothing to do with the crt used. I have
also yet to see a Philips set with a Sony crt. Where did you get this info?

Also, most posters in this group prefer bottom posting. Regardless, mixing
it up in a post is really confusing. You might want to edit your posts to
be more clear.

This is great and all, but doesn't help me much.

Someone above referred to overscan? What's that all about? Something I can
adjust if needed?
