To those of you with the wonderful Sony 40" XBR800 what speakers are you using and how far from the TV do they have to be?

We accepted delivery on Friday, I setup my JBL n26II front and N-center and noticed greenish corners. The center was right ontop of the set and the n26's were on the floor against it. After removing the speakers, and many on/off cycles, they went away. These speakers are supposed to be shielded. They are a little big to, but does anyone have a center speaker sitting on top of the set without any causing problems? Or how did you set things up so there were no problems?

Sorry if this sounds newbie'ish but it's hard to find salespeople willing or able to answer this question.

Thanks,
davidk

Well, those speakers clearly aren't shielded. A shielded center-channel speaker should work fine on top of the Sony, and not cause color distortions. Whatever you do, don't put those JBLs near the Sony again. Exposure to unshielded speakers can cause permanent chroma damage to the set. And the KV-40XBR800 isn't cheap.

Your right, I never thought I would be spending 2.5k on a TV.

The only thing is the JBL's were listed as being shielded. I'd like to sell the JBL's in favor of smaller speakers but if these WERE shielded and they caused problems, what hope do I have of finding a set that won't cause problems.
Anyone have any first person experience?
Maybe this should be moved to the speakers/subs forum?

Well, David, I've never had any trouble with shielded speakers not working as advertised. But I have ruined two previous Sonys by placing them too close to unshielded speakers (in one case, an old Polk LF-14 "subwoofer" system, and in the other near a set of old DCM Time Windows).

Quick Qestion... ive got a pair of titans and atoms in my living room... I'm building my first HT (center next week, svs following, etc.) i know the cc-170 is shielded, but are the titans?? its not too clear in the borchure, and my dealer is kind of a pain, (but he has paradigm) so i didnt ask him.can someone tell me quick?

For those of you who've been following Mike B's "Kill me" thread, mine isnt serious but i just picked up the atoms today from special order in cherry... the tweeters were loose in the speaker housing.. like i said its nothing compared to Mike's problem with spacial judgment.

thanks

From what I understand of the Titans - magnetic shielding is an option. So I would guess that if you didn't pay extra for it when you bought your speakers, you probably don't have it.

Sorry to bring this post up again, but I had to comment on the magnetic distortion.

I had my TV delivered on 12/17/02, purchased via Sony Employee discount.

Four months later, I started to notice an abnormal discoloration on the bottom left hand corner. My speakers are at least 5-6 feet away from the TV so they shouldn't have been a problem. I called Sony and they had one of their authorized repair personnel come and look at the TV. The technician played around with some magnets on the tube but could never correct the discoloration.

Two weeks go by. I got a call from the authorized Sony rep stating that the entire tube had to be replaced. Yes, the tube had to be replaced on a 5-month-old TV due to the discoloration. I was told that it was a fairly common problem with the 40-inch XBR. So the technician replaces the tube, problem solved right? Nope, tube goes in all fine and dandy, but the technician just can seen to get the picture calibrated. So now I have a brand new tube with no discoloration but the bottom of the screen is now distorted! The tech tries for an hour to calibrate it. No luck he says. Tough luck. That's the best he can do. Now I'm pissed. That's a whole other story.

Fast-forward another four or five months. Guess what? The SAME discoloration occurs AGAIN. I'm getting so fed up with this TV. Anybody else having the same problem with this TV?

Here’s a link to pictures of the TV being taken apart:

I was making decision on 36" or 40" Sony TV two months ago.
I had a chance to talk to 2 Sony authorized service depots. All three TV technicans have the same opinion and told me 75% of 40XBR800 TV and 50% of 40XBR700 TV have to be replaced the picture tubes because of purity problems. Sony has a bulletin on how to fix green spot on the left of screen by moving the yoke. But it may not work everytime.
Technically speaking, they don't recommend 40" TV because of huge sizes of picture tubes. It is very difficult or even impossible to make a good perfect alignment on all four corners, sometimes you have to live with it.

Anyway, I went for 36" Sony TV instead.

My 40XBR800 is crystal clear, with Paradigm Studio-100 standing at 1 & 1/2 feet from the set. I don,t have any problems, and this TV was one of the best buy I,ve made.

I have a Studio-CC 570 sitting directly on it, and there is no interference or any problems.

It,s an unbelievable TV, and I know what I,m talking about, because I have a Toshiba 65HDX82 in my other room to compare with.

I also have a 40XBR800, and I have a small color blotch in the bottom left corner of the screen. I've got a Sony repair guy coming with the magnets this week. The thing I wanted to mention is that this problem is not exclusive to Sony 40XBR800s, I've seen this thing crop up with other large screen sets (I've owned 2 non-Sony's where this thing cropped up). It happens with these big sets sometimes. I definately think you should, buy your XBR from a place that will replace the set with not hassles within the first 30 days. Then, pay a lot of attention to any color blotch problems during that time (especially the bottom left corner). The repair guy with magnets can't always fix the trouble if the blotch is too large, so the nightmare by the guy who posted earlier about having his tube replaced is a possibility (if a small one -- most repair guys will tell you that it happens, but it's the rare exception). I don't think this situation is a reason not to buy the wonderful 40XBR800, but it is a reason to be very careful.

i made a post a couple weeks ago, here is my story.

I have a 36" JVC HDTV and I have purity problems....................but my problems come and go.
I have noticed that i can go to bed at night, and at night time, the picture looks pretty well. But when i wake up in the morning, the corners are nto very good.

I have moved my speakers about 1.5 feet away and also moved my sub away.

Like this morning, i woke up to watch a football game and the corners were kinda bad.

But i am watching the game this evening right now, and the corners are nice!!!!

I am starting to believe it has something to do with the time of day.

Why else would it change like that??

Strange but true!!

You're right. I'm not sure if Sony is willing to replace another tube (replaced 3/2003) since my new tube is now also defective. I guess I must have been the exception huh? The repair guy did say that Sony would most likely not replace the tube, since the tube itself cost $1200.
I guess he talked Sony into replacing the tube since he could'nt fix it with magnets.
I'm definitely not trying to slam the 40XBR, but potential buyers need to be aware of the problems that my arise due to a defective tube.

i realized today that if i turn my tv off for like 8+ hours, and turn it on that the corners are bad purity. if i leave it on for a few minutes, then turn it off for a few minutes and turn it back on, it looks better?

anyone know what could cause this?

Is it maybe cause it is not warm?
