Ok, I just want to know if I have unrelaistic expectations for this set. In
the top right corner, there is a *slight* blue hue, and the bottom left a
*slight* yellow hue, only really noticeable in pure white screens. They
extend inwards, diagonally, about 1 inch. While watching TV, you don't
notice it, but when a commercial with all white or something comes on, you
can see it.

My Front speakers are older, 1996 DCM's, probably not shielded, and are 4
feet away. Moving them had no effect. My center channel is 1 foot
underneath the TV, underneath 2 shelves of glass. My sub is 12 feet away. I
took the speakers out of the room, and had my wife watch the screen, no
change. I also waved the center directly in front of the screen, to see if
it was powerful enough to affect the screen, but no change..it didn't affect
it at all.. How much distortion is tolerable, expected? Can these TV's
produce a PERFECT 100% white screen? Am I being overly anal? It seems the
only reason I see this is because I LOOKED for it. It isn't some eye
grabbing problem. I got the TV brand new on sale at Good Guys for $999.00,
so am very happy with the deal, but don't know if I am expecting things
large tubes don't deliver.

I also ordered Avia, and will be tuning the TV as best I can with that. Any
tips, suggestions as far as purity?

To start with, your set is a very good model. In any of these large CRT type
sets, it is difficult to have perfect purity under many conditions. It is
possible that there is something magnetic in the area that is effecting the
set, that has nothing to do with the speakers near by.

Just for curiosity, see if you can try changing the direction that the set
is facing. These sets can be sensitive to something metal in the walls, such
as electrical wiring, and or pipes in the walls near by.

There is a tolerance for the convergence, pin cushioning, purity alignments,
colour tracking, and all the other set-ups. Something like the purity
specifications would be very difficult to verbally convey to someone,
without doing some very precise testing, using colour analysis equipment,
mapping out the screen, and then generating a colour layout map.

In these large screen sets, I have never been able to see a set that was
visually perfect. In theory, the purity should be very near to not having
easy to see visible errors.

Thanks for the reply Jerry. Unfortunately I cannot rotate the set :/ It was
hard enough for me to get it where it is, and there is no other wall for it!
I wish I could try that though. I am going to check for pipes tomorrow.

Mentally, my mind is screwing me over by forcing my eyes to look up there
and "check" for it constantly! I did get the 5 year service plan, so I
suppose if it gets worse, or if I've had enough of it, I can fall back on
that. I turned the color to zero, to force a black and white picture, and
the whole screen does black and white except up there in that corner you'll
see streaks of blue at times. Easy to spot when black and white.

Panasonic and Sony teles have seen quite a few problems in the degauss
control circuit inclusive of the thermistor and relay (control circuit).
First, have the set manually degaussed to see if the problem goes away. if
that works then wait a couple of days to see if the symptom returns, if it
does then you will probably need to have the set serviced.
BTW depending on the physical size of your speakers it may be necessary to
move them more than just a meter or so away for the set to totally eliminate
their magnetic effect. I have seen some of the older speakers cause
discolouration even when placed three meters away form some of the large
screen crt sets.

I've encountered odd problems like this before with big screen tubes which
are as Jerry says particularly sensitive to magnetic fields including the
earths own field, radiators which may have been spot welded and are now
effectively bar magnets and even, some yrs ago, my mothers Hyundai car which
when parked 8 feet away through the wall caused purity problems on their
TV- different depending which way round the car was pointing.!

It may be possible to place a compensating magnet somewhere around the set
(experiment to see if this works for your set) You will only need a small
magnet like the one from the speaker of a small radio. I've had sucess with
this in the past.

It is also worth a reminder that TV's only degauss themselves when powered
up from cold, not from standby soa few sessions of 5-10 mins unplugged then
powered up may help the set 'acclimatise' to its surroundings
