Sony Grand Wega III Blue blob on center of screen?

Problem is in optics block. Can you see it on a non-used input with the brightness turned up?(shows clearer)

What color temp are you using ?

Try scrolling through them all and see if the blue spot changes color or has less color.

When I had the green blob on my 2020, it was worse on Warm1 and 2 and barely noticable on Neutral or Cool.

These pictures are hard to see. Except they look brightish near the center; unless that's your camera.
If you're saying a blue very softly defined blob, it's in optics block. It's something like a color diffractor that's used to separate light into red/green/blue, and it's maybe burned. Or possibly the first lense past lamp which diffuses light into a uniform brightness.

Try a Black and White show. I love Lucy,or Leave it to Beaver. I noticed mine while watching the Leave it to Beaver Pilot show that was on a couple of weeks ago.

I have a GWIII that is 4 years old this month. When my light engine needed to be replaced in January (IIRC), my yellow "etch-a-sketch" pattern was static; no change through all inputs or aspect ratio changes. As suggested before, take a look at the suspect area while viewing a B/W show.

YMMV

Here is what my VVEGA looks like, see the burn in on the left side very pronounced not as much on the right side.See the star pattern in the center , discoloration.With a color generator I can see the problem is ion the blue LCD ,The green and red appear fine.This Magenta color shows best with my camera... jo

I`ve read they are very good.Read somewhere they are one of the only ones authorized to rebuild the Sony optical blocks.

Today (12/11/07) Sony announced that they were extending their warranty on the "blue spot" issue for another set of previously uncovered models.

Mine was actually on the list this time around (KF-50WE610) and Sony even called me about a week before the announcement to let me know it was coming out. (I had already called them for troubleshooting so they had my number.)

Sony had definately made me a much happier customer than I was after I got off the phone with their support!

For all the details go to //esupport.sony.com/US/perl/news-item.pl?mdl=KF50WE610&news_id=237

Hey chiquito3, you sent me a PM but it says either you're not allowed to receive PMs or have PM's blocked:
'Yup,
Sounds like you'll be using it for what I used to use it for with my Denon 3801 which was sending HD audio over analog. This will do the trick.

I had a similar discolored area in my GWII that was most noticeable in B&W movies. They replaced the entire light engine (I think it was called). Fortunately my TV still had its extended warranty.

That warranty ended in March 2008 after 5 years. If I have any future problems with my TV, I'll likely just get another one. As good as it's been, putting several hundred dollars into a TV that has lousy black levels (though good color) doesn't make sense.

I have a 60wE610 that as a blue blob problem. Unfortunately I noticed it about two months after the 6/30/2008 extended warranty expired. And it seems to be getting worse.

Thanks to other threads on this topic I became aware this issue was not unique to me. I made a couple of phone calls to Sony Support and eventually wrote a letter to the Executive Review Committee per the Sony process. Sony made me a trade in offer on a new set. The offer amounts to a 20% discount and you keep the bad set. Unfortunately I really want a 60" screen and Sony only has a 70" for a ridiculous price of $20K, or a 55" for $7K before discount. No way am I giving Sony that much money after this bad experience. Even after the discount you can get the top of the line Samsung LN55A950 for less.

I could get a smaller set and save a couple hundred bucks, but I would also be sacrificing any future potential compensation should a class action law suit be filed. So I'm probably not going to do that either. And again I'd rather be done with Sony as this isn't my only bad experience concerning the reliability of their products.

It seems my choices are to fix the set or go with another brand. Does anyone know if replacing the optical block is a permanent fix, or will the problem reoccur in a few years? I am also tempted to write another letter voicing my displeasure, since there really is no viable 60" replacement right now.

For now I guess I'll study the threads on replacement of the optical block and see what the parts cost is and if I want to take this on myself.

The model you mentioned is covered till March 31, 2009 for warping to the lamp access door and any other damage that may have occured do to the excess heat. See http://esupport.sony.com/US/perl/new...10&news_id=261. You could check for door warping and claim the blue spots are caused by the same problem. Excess heat.

Maybe worth a try
