I have exact problem. Is anybody know how to fix it? tv is 4 years old

You may need a pixel fixer, that can be found at Wal-Mart!

It sounds like you have a bad Blue Polarizer in the light path. I'm sorry but that is something you will have to contact a service center for. It's not something you'll be able to do yourself, I'm sorry, but that's the best advice I can give you.

i am having the same issue............any solutions??

I would suggest to try to get this TV fix while still under warranty. Normally the manufacturers give one year.
In regards to the discoloration, there is not much you do but to let the Sony authorized repair center knows about it so they can fix it. Ask them if their work is guarantee as well for how long.
Good Luck.

Yellow is the lack of blue. It can happen when you are running your contrast - which is your overall light level - too high.

Try turning down your contrast. On CRT tech, contrast should always be run at half what the factory allows as full, on the user controls. Full up is what calibrators call Torch Mode, and is NOT the way to get performance to be in the linear operating range of CRT tech.

If your sides are more yellow than your middle, your set may need lenstriping. Mild yellow on the sides is not uncommon, and usually not noticed. But heavy yellow on the sides would indicate that the blue image needs work on white field uniformity.

Yellow is the lack of blue, in CRT tech.
