This is usually caused by dirt inside the light engine.  it needs to be sent in to sony or a rebuild company to be cleaned or replaced.  not user/operator repair....

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 you can find it here: http://www.discount-merchant.com/SONY-1-788-302-21-p/1175790.htm?Click=48173 . Have a blessed one!

Left half of picture has a green ghost like shade


The sounds like the light engine is bad. Sony is notorious for blobs because of the three LCD chip inside consisting of a red, green, and blue chip. The light from the lamp is reflected and then combined back together to form a brilliant picture. Unfortunately one of the chips is bad, or has melted due to extreme heat from the lamps. This can cause the color blobs on the screen. A lot of people experience blue or green blobs in the center or on the sides of their sets.

Please adjust TINT control of Video Settings in Menu that will adjust color tone of TV. I do not think this problem is related with Lamp because TV screen does not have any color blobs or spots.
Above solution is for Sony KDF-55WF655 model TV, if your model number is different, let me know.
Thanks.

Large blue blob in middle of screen on my 42" sony tv model # KDFE42A10


check to see if your green and red lamps are lighting. if they are not then go to your convergence board and check to see if you are getting the right voltages. the voltages are written on the circuit board on some tv's. i believe that you are having problems with your convergence.
