Damn.... how bad can I expect the problem to get over a period of what amount of time? Meaning, in your experience how bad do you think it'll be in 6 months, how bad in a year, etc. given a couple hours of use every day? Right now it really isn't that big of a concern as it can't really be noticed when watching images in motion, it takes a solid gray/light background for it to become somewhat noticeable; But it does bother the half of me that's so anal about picture quality just knowing it exists (even though it can't be seen much of the time) and could get worse is enough to get me to look for it constantly. I really didn't feel the need to get this thing ISF'ed before, but if it gets any worse I guess I'll have to look into it.

Sorry if I'm interrupting the thread. I was curious if any of you know how to remove the anti glare coating on the xbr960. I've searched the site and could only find one thread that said he removed it with a product called goof off at goof-off.com. He also said that he couldn't recommend his technique because it took him so long to remove it. I want to remove the glare coating for better picture. I also found out that the "960N" model has a plastic protective coating over the anti glare coating and that the regular 960 doesn't. I have the 960. It looks like I just need to find a chemical that will remove it without damaging the glass or plastic. I thought maybe that clear boxing tape you get at the post office. The reason I say from the post office tape is because thats quality tape with super sticky stuff on it and if youve ever notice that that clear tape doesn't leave a sticky residue if done right. I might practice on my windows before hand. I don't know if the coating is a film or a sprayed on substance. I've found theres different opinions on that. Im not bothered by several windows I live in an apartment thats like living in a cave. Any thoughts?
P.S. If you like the coating and want to keep it never use any tipe of liquid ever not even electronics cleaner to clean it get one of those special cloths used to clean televisions.

When it first turns on and degausses itself there sometimes appears to be a dark area of discoloration that remains on the lower left hand portion of the screen.... displaying on a screen of a solid light color it is barely noticeable (yet still noticeable,) hardly noticeable at all (or not noticeable most of the time) when watching moving imagery.

My speakers are magnetically shielded so I know my left front can't be causing this problem.

Anyone have any idea what the issue is? I just don't want it to get worse (it didn't do this at all when I first purchased the set.) The set isn't professionally calibrated or anything but it is still optimized as much as it can be using Avia (and suggestions from this thread.)

The TV is plugged directly into the wall and is never left on after I'm done viewing it (which amounts to only an hour or two each day on average.)

I have the same problem with my 960. I thought that maybe its from the speakers inside of the television. I don't know though. I'm not too worried about it becuase I'm going to have mine ISF'd soon and maybe he can reset the "landings " or whatever. I know that their are ways to go into the service menu and do something to the landings yourself. Supposedly its really easy. Maybe do a search with "landings" or "degaussing" or "spot" or something. Mine is most noticeable when my xbox 360 starts up on the screen and all you see is the green xbox logo and the white background. Its a bluish color for me. A person told me once that the magnetic poles of the earth could do this. Like if you have your television facing south or north or something. Not kidding. I know that I've seen on this forum somewhere someone talking about how if you move your television around to a different place in the house that it can affect the geometry of the set. Sorry that I don't have detailed info on this. I'm just an amateur with poor sentace structure and bad puncuation etc.

I'm having the same problem.

The authorized sony repair guy will be coming to take my XBR960 in the next day or two, to replace the tube on Sony's recommendation to theoretically solve the reoccuring color-blotch problem in the corners of the screen, because "they don't know what else to do".

Can you provide any hard evidence available on the web, or contact names and phone numbers whereby I can track down evidence that this major surgery is NOT the solution?

Any idea if when the tube is replaced, they re-use the old yoke?

I had my 960 repaired for the no picture and sound problem. The techs replaced a DZ and By board. It seemd as though the PQ wasn't as good after the repair but with D* I wasn't sure if it was an issue with them. Now I'm certain it's the tv. Color reproduction is fine but HD looks like SD, my sony 30hs510 has way more detail. I tested different HD receivers and both HDMI and Component cables. Can the blurry PQ be corrected with calibration. Can the techs test the resolution of the set? The tech said he reset the tv to factory settings but I've read factory settings are build settings which were before Sony's calibration of the set. I'm just curious if it's a hardware issue or a settings issue as I have an ISF appointment scheduled.

I'd ask Sony to recalibrate it if they reset you to the initial defaults...
post #4628 of 7880
I originally did home repair but it was too stressful, having to schedule around my days off and not being able to leave my home as they give you a 4 hour window, plus time of repair. I had 4 scheduled visits with them cancelling once, it wasn't a good experience. Hopefully they can pick the set up, do extensive testing to make sure it's correctly fixed, and then returne it. I will call them tomorrow.

Because of various issues, pickup of my 34XBR960 has been delayed. I'm still requesting pointers to or personal experiences with any credible evidence that the infamous 34XBR96 "color blotches in the corners" issue can be solved by any method other than replacing the tube.

If Sony cannot be persuaded that the issue lies with the deflection yoke (or something else), they are going to replace the tube.

In fact, I'll expand my search to requesting direct evidence that the problem CAN be solved by replacing the tube.

I just want my set to work properly ...
post #4630 of 7880
Ladd, I'm with you. I don't care what Sony does or does not replace, as long as the set works like it's supposed to. I just got off the phone with the techs and they're picking up my set this wednesday. If they tell me they need to replace the tube, as long as it's another SFP tube I couldn't care less. In fact I'd prefer having brand new parts as long as they're functioning properly. I think the other poster is saying even a tube replacement won't fix the green blob issue because it's not caused by the tube but rather something else. If that's the case hopefully they will discover that the problem was a "combination" of the crt tube and the yoke.

i work for a very big electronics store and exploring our system i found we still have 4 xbr960s in stock, i also found out we have used xbr960n's

does this anti-glare coating really have an effect? is it worth getting the 960N used so it doesnt have it? or should i go for the new 960
post #4632 of 7880
I would buy a 'new' xbr960 over a 'used' xbr960n any day of the week.
post #4633 of 7880
so it is said that they xbr960's coating will get dusty and screw up viewing, can anyone thats owned one for a while elaborate on exactly what the problem is and how bad it can get? and if its fixable at all

Yes by all means get the new 960. The anti glare coating shouldn't be a deal breaker either way. But "new in box" is a fine selling point. btw i have a 2year old 960 and actually prefer the anti glare coating.
post #4635 of 7880
Without the anti-glare, you run the risk of reflection, seeing yourself watching TV, lights, windows, very reflective with out it.
post #4636 of 7880
My 960 is just about 2 years old now, and no dust problems I can see with the coating. I like it because it cuts down on the reflections from lights in the room.

By all means, get the 960! You are amazingly lucky to still have one available new.

yeah not just 1 but 4

post #4641 of 7880

post #4642 of 7880
This is Not fair!!
I thought I had the last xbr960.
Now I will have to change my handle to almostlastxbr960.
hahaha
post #4643 of 7880
So far I'm very happy with my 960. I do notice that there are vertical dark bands at the left and right sides of the screen that appear even when the set is off. They don't bother me much, as when its on, I don't notice them unless I really look closely. Is this normal (the set, not me!)?

Easy Service Menu fix. Adjust the 'Landing.' Color purity problems will be basically eliminated. Trust me, it's worked on mine.

Once you're in SM, you just need to find the adjustments for the Landing. You have the option to adjust Right Top, Right Bottom, Left Top, Left Bottom. You can adjust the landing values by using numbers 3 and 6 on your remote. 3 brings 'em up, 6 takes them down. Have you been in the service menu yet, Stinky?
post #4647 of 7880
I tried removing the antiglare coating with goof-off and messed up. I applied it to the corner of my screen to try it out and it did work but decided not to do it to my whole screen because the screen is way way too reflective without the anti glare coating. I did mess up a little and took some of the coating off in the viewing area about 1/2 inch. It's noticible when there is a white image on the screen but only if your looking for it. I would not suggest taking the anti glare coating off of any screen for many reasons. The coating is a must have because the screen is so reflective. Also, I have found that the screen is NOT GLASS! It is very hard plastic. Don't ask how I know this. It too difficult an imbarrising to explain. It was a tolerable mistake though. Not in the viewing area from the front but it is from the far side viewing angle. There might be glass underneath the hard plastic though. Anyways just wanted to warn everyone. I'm sure everyone is smart enough not to put chemicals on their very expensive television though.

Thank you for taking the time to answer (and perhaps your solution, also proposed by others, works for some), but you must have missed all the postings in this discussion thread detailing how adjusting the Landing values is not always an effective solution.

As has happened with other community members, on my 34XBR960 adjusting the landing values works fine until the set is turned off for the night, but the color blotches are there again the next day.
post #4649 of 7880
Did you save the new landing values using the special key sequence? If not, they will be reset when you turn the set off and on.

Interesting. I've had to adjust the Landing values twice since I got the set. In my upper right hand corner there is a slight yellowing that I can't get rid of. But it only shows up in very very particular cases. 95% of the time I don't see it. I also forgot to mention that, when I got my set ISF calibrated, that I had it manually degaussed. That may have helped but I don't believe it did. I believe the Landing adjustment was enough. Folks who see the blotches persist after a shutdown should wait long enough for the set to degausse itself. When you turn the set on you'll hear a big "whooooom" sound - that's the set degaussing itself. Turning it off right after adjustments without letting it degauss could lead to further blotching. I guess I've just been one of the lucky ones.

I also have to mention that there's only a single magnet on my tube. Some tubes come with many magnets which could absolutely be creating the color blotches. Removing magnets will affect geometry but you can also make more adjustments after that. If the Landing hasn't been the solution than I recommend removing some of the magnets on the tube and see what happens. In many cases it's the magnets that are introducing the color blotches.
