    Check your manual and menu for an alignment adjustment. Sounds like Blue is slightly off. Take a close look at White Text on black for the blue edge. Good luck

This is a failure of the optical block of your TV. This was an inherent problem for your model. The only way to fix it is to replace the optical block. It is very expensive (over $700) and time consuming (takes over a hour for an experienced technician).

Sony extended the optical block warranty for your model that covered parts and labor but it expired on June 30, 2008. Contact Sony, they might be able to pay for at least part of the repair.

Here is a link to the Sony response to the issue with pictures: http://7402519399385937065-a-1802744773732722657-s-sites.googlegroups.com/site/sonylcdrptvproblems/sonyrearprojectionlcdtv-opticalblock/2003GrandWEGABlueHazeAdditionalCoverage.pdf?attachauth=ANoY7cqH-wG8F6xCLp07es9MJWf0B9tr36oyw8conVtRyMlYrQTo-iZ-dba8Nq2VTMzjXKhDY_FEX-ho-9o2iYDqTkzqtsoHY1URYyWt2tAuoQZN7XMvcCPOiA4bgQupIqffnXIuB0ldeVn8bbMwfxVB7Y9cTbRXUxV_eVqVk1YuV-m_ElE7jhtlxfQ5eG6zRY6dCmnVl-_e-eGOFdgcddmrc_Vz2iRgCGkPBL3wZAK3-KFHw2kRV-w7AHaV6-A-OqHnbU8hCU0CkFwDL-6kvxWwhg-Vn4fwsDFHLeOXn3xNgvjoxPt6i6E%3D&attredirects=0

Blue cloud on the bottom center of the screen Sony xbr 70


If this is a KDSR50XBR1 or a KDSR60XBR1,
It is a bad Optical Block and you need to call Sony at 1-800-222-SONY asap to get a exstended warrenty repair. If it is not, and it is out of warrenty I would still call to see what they will do. In either case, it is a Optical Block causing the problem.
Hope this Helps,

Blue line problem with Sony Grand WEGA KDF-55WF655 Rear Projection TV.


We had the free repair from SONY for the blue dots and splotches. It works great now but you need to hurry and contact them as the offer expires I believe in December.

FAINT PURPLE/RED PATCHES APPEAR ON SCREEN


http://esupport.sony.com/US/perl/news-item.pl?news_id=206
thought I would let you all know of the recall.

For models:
Models: KF-42WE610, KF-50WE610, KF-60WE610, KDF-70XBR950, KDF-60XBR950, KDF-42WE655, KDF-50WE655, KDF-55WF655, KDF-60WF655, KDF-55XS955, KDF-60XS955, KF-42WE620, and KF-50WE620.



/This is a free repair on the optical block/engine. For specifically a road mapping issue. (Where there is sparactic grouped lines on the screen of the TV)

Otherwise there is a full recall on all 50XBR1's and 60XBR1's for ANY video issue.
But the bullentin I do have on that is Confidential due to the amount of claims SONY could recieve. But here is a sample of the bulletin.

Models: KDSR50XBR1, KDSR60XBR1

Subject: Optical Block: Warranty Policy and Part matrix by serial number.

Resolution: As part of Sony’s commitment to quality, Sony is announcing that it is extending the limited warranty (parts and labor) for optical block replacements on the models listed above until October 31, 2008, regardless of purchase date. Authorized servicers should follow the normal process for warranty claims for this issue.

You have a bad light engine or in Sony TV sets, it is called an Optic Unit Block Assembly. This is a very expensive part and should not be attempted to be replaced by a novice. Call an authorized Sony repair place to have this repaired. Good Luck
