Question about Sony Grand WEGA KDF-50WE655 50" Rear Projection HDTV

1 Answer

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

I have been reading about other people that have the blue line problem with similar models. My TV is a 2004 and I realize that Sony will replace the Optical Block if this is the diagnosis. Is there anyone that has experienced this blue line problem that had it repaired? Did it turn out to be the optical block? I do not have the blue dot or haze issue...mine is a blue line that runs from the left to just over half way across the screen and it is getting worse. It develops after the TV has been on for a short period of time at the top edge of a wide screen movie lower bar or other stationary object at the bottom of the screen. Any time a scene or picture is stationary for an extended period of time, a blue witness line will appear around the stationary picture. If the TV is turned off for a period of time, the lines will disappear and reappear when another stationary picture appears.

Has anyone experienced this, attempted to repair it and found that it was in fact the Optical block? Sony believes it is probably the Optical block but I have not actually taken the TV in for diagnosis yet. They offered me the TV deal as well, but I have several reasons to stay with the current TV.

Any help with this topic would be appreciated.

Kind regards,
Chris Masterson

    The blue haze appears after the tv has been on for a short time in the left lower corner of the screenand extends about halfway actross the screen. If you examine the blueline close up it appears tp to a ghost pattern from a stationary display or tool bar type image that is bleeding through after it geats warmed up. For example, if I put the DirecTv menu up for a few minutes, it seems to remeber the pattern in the left hand corner of the screen that was there when the menu was up. If I change the screen to something else it remembers that image.

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.
