Question Blue spot on sony 50" when screen is dark?

One thing i have noticed with my sony kdf50we655 is when scenes are very dark or black there is a dark blue area on screen, almost unnoticeble with lights on but at night with lights out it becomes much more evident especially bec its in the top middle portion of the screen abt 3" in diameter. The manual actually refers to something like this being normal but it doesnt seem possible, its not as bad as rainbows flashing at me or audio being out of sinc like with the sammy 5063w tht i exchanged but it seems it wouldnt bother me as much if it were off to left or right, but right in the middle is bothersome. Anyone else have this issue the manual says the color may be blue red or green?

I want to exchange tv but this would be the second tv ive exchanged first sammy now this one. Im also not sure if all LCDs have a similar issue like the manual suggests.

If you have an LCD and have seen this in the dark areas of a scene in any color please let me know (its more noticeble when lights off). I still have 3weeks left if i want to return it but i picked the last two tvs up myself (didnt want to pay delivery) and cant take much more hauling hd tvs around. LOL

Default Call Sony

Hello, I have a Sony KF60WE610 60 inch LCD TV and do not have the same issue you have but I am curious to know what is going on with your set. Do you have the problem with all video sources? Are all of your devices ran through your audio reciever? If so have you tried connecting them directly to your TV without going through the reciever? The light they refer to in the manual describes ambient light being reflected back off of the screen. But you say you turn all of your lights off so that should not be the case. Have you seen this issue with other sets on display? If you have a high end video store nearby, go look at another set to see if it has the same issue. If not call Sony and they will have a repair tech come to your house and check it out. If they come three times without fixing it they will bring you a new TV. I love my Sony LCD and would not trade it for any other set for the money. Good Luck!!!

This effect is the tv not the source since i can see it when on vid 1 sat, vid 5 xbox component, vid 6 dvd component and vid 7 dvd hdmi. i will prob call a tech first before exchanging it since i have the service plan for 2yrs and actuall paid less then new for the tv since it was a display and if i exchange i will have to pay full price.

Default What about the lamp?

I recently had a lamp put in my Sony LCD under warranty because my picture quality was getting bad. The picture seemed dark and colors that used to be bright and sharp seemed to bleed together. My TV was only 8 months old when it got it's first lamp. You said your set was a display, so there may be alot of hours on your set and your lamp could be to blame. I would go look at a new one and if the picture seems brighter and sharper, it could be the cause. I could'nt believe the difference after mine was fixed. Sony will replace it for up to a year free. (or your ext warranty should cover it). Hope that helps.

Thanks for the advice i will go look at some sets at the store but mine is still bright and sharp just when screen is dark or fades to black you can see a round blue area in the top middle area of the screen then when the scene is light again it seems to immediately go away
I was just hoping someone familair with this problem could tell me if it could be fixed by a tech since i have the service plan or if i have to dish out the cost for a new tv if it has to be exchanged since i paid less for my floor model. or if this issue is inherent in someway to all LCDs

Default No need to spend more

Although you purchased a floor model, you still get the full manufacturers warranty. At no cost to you, Sony will have a service tech come out and evaluate your issue. If they cannot fix the tv within 3 service calls, they will give you a new one. This may be a hassle, but the end result would be you with a brand new set possibly a newer model for what you origonally paid. I think it's worth it. I have a Sony LCD and do not have the same problem nor have I seen it with any other set. Call Sony at 1-800-222-7669 they will give you an event # and schedule a service call.

Are you sure this is not just the reflection of ambient light from your room? That reflection can be seen as a whitish patch in the middle top of screen when TV is off or between scenes.

Default "Blue Bleed" in the Black screen

I have begun to experience this problem recently. My Sony is several years old, now and I have yet to replace the Lamp. For some time I was getting a high whining noise, like that of a Fan about to fail, but the fan(s) have not failed and the squeal has gone away. This has happened a few times...it comes and remains for several weeks or months, then goes away, only to return again. As of this writing it has not returned. My only problem now is the "Blue bleeding" in the Blacks, in a specific area of the screen; in my case at the lower right corner, and a slin sliver along the entire width lower edge of the image area and a smeering withing the center area of the image area.
Before I call for service I will investigate all forums that might render a glimpse of a cure ro resolution to my problem.

Howdy, I recommend watching this website: http://www.howstuffworks.com/lcd.htm it will explain you how lcd works.What I am thinking is that maybe the blue chip is going bad or if what prevents the light in order to stay black is failing.Hopefully this will help you out.

HI,The light of the lamp is always on and in order to make the scene dark the tv uses like dark shades to cover the white brightness,maybe your lampis so bright and that's why you get the color blue.Or maybe one of the lcd chips is not working propertly.Good luck,God bless you house.

This is definitely valid, happened to me before & I was baffled for a long time

This sounds like the Blue Blob issue that Sony is extending the warranty on this issue. You should call Sony and escalate it to the higher ups there who know about this and do not forget to mention that this has been an issue for a while and you just heard about the extended warranty coverage on this just in case the period of extended coverage has ended.

Good luck!

This is a very common problem with Sony rear-projection LCD TVs. Pretty much all of Sony's rear-projection LCD TVs have been the subject of voluntary warranty extensions, class action lawsuits, or both due to inherent latent defects in the optical blocks, which contain the LCD panels. Unfortunately, most of the extended coverage has now ended, leaving thousands of customers out of luck, and the repair costs >$1,000. See my support web site for additional details:
