Re: Yellow spot on the screen
You have a bad optical block. Sony has extended the warranty on your TV so the block will be replaced for free. Go here for more information: http://ciscdb.sel.sony.com/perl/news-item.pl?news_id=185&mdl=KDSR50XBR1
Better call a repairman. Ours did that (and so did my sister's) and it turned out it was the optical block which SONY warranted. They must have had trouble with it because they kept extending the warranty on that particular part. Might want to check to see if they still honor it.

The set if projection which model here is, has arced and now each of the three picture tubes used has a tiny permanent burn mark on its screen.
That is what you are seeing, the set uses three picture tubes with screens like the old tv sets===the coating has been burnt in each, want to prove it, remove rear cover and cover any one of the three lens and that mark on one tube will go a way.
Can you still see the spot when the TV is off? In any event, the screen may have something on it or the mirror that reflects the image from the projector where the bulb is. Make sure the projector bulbs are clean. Good luck, thanks for using FixYa.
Hi , it seems you are experimenting a light engine problem.Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!
Yes, I do. It needs a new light engine. Very costly repair. However, Sony has extended the warranty on many of these LED projector sets. You need to call a local Sony authorized service center and see if your model is covered. Otherwise this repair could run over a thousand bucks.
Sorry, but there is no cheap method of repair for this unless it is in warranty.
This TV will require replacement of the LCD Prism unit.
This Prism blocks and allows colors so that the 3 LCD images may be mixed to produce the final image you see on the screen. When this becomes damaged or defective, it leaks colors (light). This Color Leakage apears as spots on the screens.
Where you see the spots is where the specific spot on the prism that is leaking light, the specific color that is leaking also.
This parts cost alone is normally $500 to $1000 dollars but is usually replaced under warranty.
I have no suggestions but I am having the exact problem, yellow haze in the top right corner of the screen with a yellow line running down to the bottom of the screen.
I guess we need to call tech support.
